SCHNEIDER ELECTRIC ROBERTSHAW VIBRATION PRODUCTS

Robertshaw vibration switches and monitors minimize production shut down time and repair costs by measuring the total accelerated force (shock) present on a machine. Individual acceleration measurements are summed to yield the total destructive force acting on a machine. This information enables you to proactively and stategically maintain equipment. Our vibration models range from the standard traditional to new technologically enhanced models. All provide unsurpassed dependability

Robertshaw Vibration Switches and Monitors protect machinery against unnecessary shut down and repair costs, so businesses can maximize their productivity. Our wide variety of models can meet any protection need.

Typical Applications include:

Robertshaw Vibration Instruments can be used on rotating or reciprocating machines. To select the proper instrument for your machine, follow the link to Selection Guide Matrix and/or 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.

The 365A and 366 Vibraswitch malfunction detectors provide maximum protection for large motors, pumps, compressors and other rotating or reciprocating equipment by responding to mechanical malfunctions the instant they occur. The 365A is UL and c-UL certified Explosion-proof, and Type 4/4X & IP66 Weatherproof, E365A is ATEX certified,. The 366 is NEMA 4 and CSA certified.

The 375A and 376A Vibraswitches are identical to the 365/366 models, except that they incorporate built-in electronic starting, monitoring or combination starting and monitoring time delay circuits. The 375A is FM approved. The 376A has a NEMA 4 enclosure. Both require 120 VAC power.

The EURO366G Vibraswitch malfunction detector provides maximum protection from rotating and reciprocating of large motors, pumps or compressors. It is intended for indoor or outdoor use in hazardous or non-hazardous areas with ATEX and CE certifications.

The 368 pneumatically operated Vibraswitch constitutes the most effective known method of avoiding costly damage due to mechanical malfunction of rotating and reciprocating machinery where air is the operating control medium.

The 566 velocity acceleration vibration monitor employs totally solid state circuitry. Sensing mode, whether velocity or acceleration, is field selectable without loss of accuracy.

The 570B loop-powered, stud mount, vibration transmitter provides a 4-20 mADC output proportionate to vibration. This unit, known for its compact size, has a two-pin connector that mates with a splash-proof connector/cable assembly.

The 571A loop-powered, stud mount, vibration transmitter provides a 4-20 mADC output proportionate to vibration. This unit measures acceleration or velocity in three different ranges and is reverse polarity protected. It is compact in size and a 1/4-28 tapped hole and stud are provided for mounting. The two-pin connector mates with a standard MIL-C-5015 two-socket connector with a boot that provides weatherproof and splash-proof connection.
