P&F Ultra Sonic Sensors

Pepperl and Fuchs manufactures Ultra Sonic switches and sensors.

Pepperl and Fuchs Ultrasonic sensors present the ideal solution for non-contact position and distance measurement in all industrial areas where environmental conditions such as dust, smoke or steam may affect the sensors. Objects consisting of a variety of materials can be detected to within millimeters regardless of color or shape.
The ultrasonic sensor produces a data carrier utilizing very high frequencies that are outside the human’s audible range. The time it takes for that ultrasonic wave to pass between the sensor and the object is the value for the distance or the position. Ultrasonic sensors have proven their reliability and precision in many industries, including lumber and furniture, construction materials and equipment, farming equipment and in level control applications.
Pepperl+Fuchs’ ultrasonic sensors currently encompass twelve series of mechanical designs for through-beam, direct detection and retro-reflective operation. Customer and application specific custom solutions underscore our technological competence in this area of sensors.
Product features:
Devices with TEACH-IN functionality for fast and simple installation
ULTRA 3000 software for improved adaptation of sensors to applications
Adjustable sensitivity to the sound beam width for optimized adjustment of the sensor characteristics according to the application
Temperature compensation - compensates for sound velocity due to varying air temperatures
Synchronization input to prevent cross-talk interference when sensors are mounted within close proximity of each other
Sensors with digital and/ or analog outputs

A Pepperl and Fuchs ultrasonic through-beam sensor consists of a transmitter and a receiver that are installed so they are facing each other.
The working principle of ultrasonic through-beam sensors is based on the transmission of a sound wave from the transmitter to the receiver being interrupted by the object that is being detected. The transmitter generates an ultrasonic signal that is evaluated by the receiver. When the ultrasonic beam is damped or interrupted by the object being detected, the receiver output switches states.
No electrical connections are required between transmitter and receiver and the functionality of the ultrasonic through-beam sensors is also independent of the installation location. To prevent dirt particles from accumulating, however, we recommend placing the transmitter facing up when components are mounted vertically.
Product Features:
Long detection ranges since the ultrasonic beam only travels in one direction
Short response times
Less subject to faults and thus very suitable for applications in difficult conditions
Additional installation expense since both units have to be wired.

In the direct detection system,

The transmitter and receiver are in the same housing in this type of ultrasonic sensor. A single ultrasonic transducer is switched cyclically between transmit and receive mode. The object itself acts as the sound reflector.
Product features:
The sensing range depends on the reflectivity of the object, including the surface properties and the angle of incidence. These effects can be compensated for (within limits) by a sensitivity adjustment
Low installation expense, since the sensor consists of just one unit
Sensitive to changes in the reflective properties of the target
Dual transducer system
Placing separate transducers for transmitting and receiving next to each other in the same housing significantly reduces the blind range since there is no need to wait for the transmitter signal to decay.
Ultrasonic sensors with discrete outputs and analog outputs are available as direct detection sensors. All direct detection sensors that support the "Window mode" output function can also be used as retro-reflective sensors (see retro-reflective sensors).

Ultrasonic Switches and Sensors

Sords Electric sells Ultrasonic Sensors and switches. Ultrasonic sensors use sound waves for sensing.

Ultrasonic sensors are commonly used for a wide variety of noncontact presence, proximity, or distance measuring applications. These devices typically transmit a short burst of ultrasonic sound toward a target, which reflects the sound back to the sensor. The system then measures the time for the echo to return to the sensor and computes the distance to the target using the speed of sound in the medium [1,2,3].
The wide variety of sensors currently on the market differ from one another in their mounting configurations, environmental sealing, and electronic features. Acoustically, they operate at different frequencies and have different radiation patterns. It is usually not difficult to select a sensor that best meets the environmental and mechanical requirements for a particular application, or to evaluate the electronic features available with different models. Still, many users may not be aware of the acoustic subtleties that can have major effects on ultrasonic sensor operation and the measurements being made with them.
The overall intent of this article is to help the user select an ultrasonic sensor with the best acoustical properties, such as frequency and beam pattern, for a particular application, and how to obtain an optimum measurement from the sensor. The first step in this process is to gain a better understanding of how variations in the acoustical parameters of both the environment and the target affect the operation of the sensor. Specifically, the following variables will be discussed:
• Variation in the speed of sound as a function of both temperature and the composition of the transmission medium, usually air, and how these variations affect sensor measurement accuracy and resolution • Variation in the wavelength of sound as a function of both sound speed and frequency, and how this affects the resolution, accuracy, minimum target size, and the minimum and maximum target distances of an ultrasonic sensor • Variation in the attenuation of sound as a function of both frequency and humidity, and how this affects the maximum target distance for an ultrasonic sensor in air • Variation of the amplitude of background noise as a function of frequency, and how this affects the maximum target distance and minimum target size for an ultrasonic sensor • Variation in the sound radiation pattern (beam angle) of both the ultrasonic transducer and the complete sensor system, and how this affects the maximum target distance and helps eliminate extraneous targets • Variation in the amplitude of the return echo as a function of the target distance, geometry, surface, and size, and how this affects the maximum target distance attainable with an ultrasonic sensor
Fundamental Ultrasonic PropertiesUltrasonic sound is a vibration at a frequency above the range of human hearing, usually >20 kHz. The microphones and loudspeakers used to receive and transmit the ultrasonic sound are called transducers. Most ultrasonic sensors use a single transducer to both transmit the sound pulse and receive the reflected echo, typically operating at frequencies between 40 kHz and 250 kHz. A variety of different types of transducers are used in these systems [4]. The following sections provide an overview of how the sound pulse is affected by some of the fundamental ultrasonic properties of the medium in which the sound travels.
Speed of Sound in Air As a Function of Temperature In an echo ranging system, the elapsed time between the emission of the ultrasonic pulse and its return to the receiver is measured. The range distance to the target is then computed using the speed of sound in the transmission medium, which is usually air. The accuracy of the target distance measurement is directly proportional to the accuracy of the speed of sound used in the calculation. The actual speed of sound is a function of both the composition and temperature of the medium through which the sound travels (see Figure 1).

Carlo Gavazzi’s UA Series ultrasonic sensors are designed for both distance measurement and object detection in tough environments. The range consists of both M18 and M30 housings. Discrete output types are available for presence and absence detection, and are ideally suited for detecting objects,such as transparent objects, that cannot be reliably detected by other sensors.Analogue output types are available on our sensors for applications requiring a measurement of the target object, such as detecting the level of fluid in a tank. The analogue models have your choice of 0-10 VDC or 4-20 mA outputs. Our more advanced ultrasonic sensor models incorporate teach functions, which allow the set-points to be configured with the push of a button, and via Windows-based software for applications where greater control of sensor parameters and variables is required. The Windows version also allows for settings to be saved and downloaded to multiple devices.

Proximity Sensor and Switches

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagneticor electrostatic field, or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensormight be suitable for a plastic target; an inductive proximity sensor requires a metal target.

Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object.

Inductance is the property in an electrical circuit where a change in the electric current through that circuit induces an electromotive force (EMF) that opposes the change in current (See Induced EMF).

In electrical circuits, any electric current, i, produces a magnetic field and hence generates a totalmagnetic flux, Φ, acting on the circuit. This magnetic flux, due to Lenz's law, tends to act to oppose changes in the flux by generating a voltage (a back EMF) in the circuit that counters or tends to reduce the rate of change in the current. The ratio of the magnetic flux to the current is called the self-inductance, which is usually simply referred to as the inductance of the circuit. To add inductance to a circuit,electronic components called inductors are used, which consist of coils of wire to concentrate the magnetic field.

A capacitor or condenser is a passive electronic component consisting of a pair of conductors separated by adielectric (insulator). When a potential difference (voltage) exists across the conductors, an electric field is present in the dielectric. This field stores energy and produces a mechanical force between the conductors. The effect is greatest when there is a narrow separation between large areas of conductor, hence capacitor conductors are often called plates.

An ideal capacitor is characterized by a single constant value, capacitance, which is measured in farads. This is the ratio of the electric charge on each conductor to the potential difference between them. In practice, the dielectric between the plates passes a small amount of leakage current. The conductors and leads introduce anequivalent series resistance and the dielectric has an electric field strength limit resulting in a breakdown voltage.

Inductive switches can be used for counting of metal objects and detection of metal objects with any contact.

Capacitive Switches can be used for level control of water, plastics, foam products or food products.

Both Inductive and Capacitive switches can be made with NAMUR outputs so that the switches can be put in hazardous areas. The connections do need to go through a intrinsic safety barrier.

Most proximity switches are barrel shaped in the 5mm, 12mm, 18, and 30mm diameters. Also very common is the limit style proximity switch. Barrel materials are crastin, plastic, stainless steel, and nickel plated brass.
