The Robertshaw vibration switch is designed to protect rotating and reciprocating equipment against serious damage in the event malfunctions occur which maybe detected as an increase in vibration.  Both amplitude and frequency of vibrations as so that an increase over normal in either will actuate the vibration switch.  When the vibration level of a machine protected by a vibration switch exceeds normal by a preselected amount, an internal switch is actuated providing a shut down circuit before costly damage occurs.  An audible or visual warning system may also be wired into the switch to signal when the malfunction has occurred. Falling bearings, broken blades and similar malfunctions cause increased imbalance or high frequency vibrations, detachable with the Robertshaw vibration switch. The Robertshaw vibrations switch is designed for maintenance free service in permanent locations.

Two types of the vibration switch are available. The Robertshaw/Uniline 366 and 365/365A series.

The 366/6000-00 series are enclosed in a general purpose housing which meets weather resistant NEMA 4 specifications.
The Uni-Line/Robertshaw 365A/6000-10 vibrations switch conforms to specifications for use in hazardous locations with a NEMA 7 housing the meets Class 1, Groups C and D and Class 2, Groups E, F and G hazardous area classifications.

The difference in the switch part numbers are the RESET coil voltage and either SPDT OR DPDT switches. Note: All switches can be manually reset after a fault.

Installed 365A Switch

The Model 365A and #365A Vibraswitches empty a magnetic circuit opposed by inertial and adjustable spring forces in the actuation mechanism. Operation of the Vibraswitches is as follows:
The armature is constrained so as to respond to only one direction of movement by frictionless flexure pivot compost of two overlapping blocks and a leaf spring leaded in one direction to hold the blocks together.  The armature totals on the pivot being forced in one direction by the adjusting spring force and the other direction by the magnetic force.
Then the entire assembly is subjected to vibration perpendicular to the base, the peak acceleration times the effective mass of the rmatureproduces an inertial force, aided be the adjustable spring tending to pull the armature away from the stop pin and the restraining force of the magnet.  When the peak acceleration exceeds the set point level the armature leaves the stop pin, increasing the gap and decreasing the force with the armature continuing to move up until it reaches the latch magnet, actuating the switch during its upward travel.
RESET is done by depressing the RESET button or applying power to the electrical reset coil.

Robertshaw Selection Guide for Vibration Switches

Industrial Vibration Switches from Robertshaw ~ Selection Guide

Buy Robertshaw Vibration Products HERE!

Robertshaw Vibration Instruments can be used on rotating or reciprocating machines. To select the proper instrument for your machine, follow the steps below.

1. Select the unit that meets the environmental conditions that your machine is located in [hazardous area (explosion-proof or I.S.) or non-hazardous; temperature range].
2. Select the power supply and/or remote reset voltage required.
3. Select the unit that provides you with the required measurement type, range and frequency for your machine. The type would be acceleration (G's) or velocity (IPS). The range would be the G range or IPS range. The frequency would be in Hertz (RPM of machine ÷ 60).
4. If you require time delays (Start, Monitor or Start & Monitor delays – see note below), select the instrument that offers that feature. Models 375A/376A series offer fixed time delays; Model 566 offers adjustable Monitor Delay; Model 563A MUST BE used with Vibraswitch Model 366 or 365, and provides adjustable time delay for the units that are connected to the 563A Monitor. If time delay is not required proceed to step 5 below.
5. Select the function that you desire:
   1. Alarm or shut down only by:
      1. Electrical SPDT or DPDT Switch Operation (Models 365/366, Models 375A/376A with Start Delay Only).
      2. Solid State Triac Switch Operation (Models 375A/376A except for Start Delay ONLY Model which has SPDT Switch Contacts).
      3. Pneumatic Operation (Model 368).
   2. 4-20 mADC output only (Models 570B/571A).
   3. 4-20 mADC output with alarm and/or shut down contacts, triac outputs (Model 566).
6. Check to see if the Model selected above has a mounting configuration suitable for your application. All units are surface mount except for the following:
   1. Models 570B/571A are stud mount.
   2. Model 563A Monitor is used with the surface mount 365/366 Vibraswitches to provide adjustable start and monitor time delays.
7. After you have made your selection, review the complete Product Specification Sheet to verify your selection is correct.
   
   
   NOTE:
   Start, Monitor, or Start & Monitor Delays are used to prevent unwanted shut down or alarm during start-up or normal operation of your machine.
1. Start Delay: Prevents unwanted shut down when excessive vibration exists (which exceeds the set-point of the vibration switch or monitor) during the start-up of the machine.
2. Monitor Delay: Prevents unwanted shut down when short excessive vibration spikes occur (which exceed the set-point of the vibration switch or monitor) during normal operation of the machine. Spikes are typically caused by detonation, cavitation, other machinery in the immediate area, etc.
