The CMCP535 Displacement Transmitter is compatible with both 100mV/In/Sec Piezo Electronic (Accelerometer w/Velocity Output) and 500mV/In/Sec Electro Mechanical Velocity Transducers and is available in English or Metric scaling. The CMCP535 provides constant current power (if required), checks for faults, processes the vibration signal to determine overall amplitude, and outputs a 4-20 mA dc current that is proportional to a user selected range of 5, 10, 15, 20 or 25 mils (metric equivalent of 127, 254, 381 508 or 635 microns). Combining transmitters with an existing PLC or DCS system results in a high density, low cost vibration monitoring system.

The Optional Alarm Module provides ok, alert and danger relays, selectable time delay, trip multiply, bypass and 0 to 5 VDC outputs for displays. The relay outputs can be used to trigger machine shut-down or other alarms. Combining transmitters with an existing PLC or DCS system results in a high density, low cost vibration monitoring system.

Alarms relays and trip multiply are available with the Monitor version.

Alarms - The CMCP500A Series Monitors have two independent set points, with LED alarm indicators and output relay contacts (Alert and Danger). Set points are adjustable via potentiometer, from 0 to 110% of full scale. Each has an adjustable delay of 1 to 10 seconds. SPST Relay contacts are rated 5 Amps @ 30 Vdc or 250 Vac for resistive loads.

Relay contacts can be independently configured by the user for either Normally Open (NO) (Standard) or Normally Closed (NC) operation. Relays are normally de-energized and can be configured for latching or non-latching (standard) operation. Latched alarms may be reset locally or by remote contact closure.

Trip Multiply - The monitors have set point multiplication of 3X via contact closure (2X available). To avoid tripping the alarms during machine start-up.

Buffered Output:

A BNC connector mounted on the front of the unit provides access to the buffered transducer output signal. This includes both the unfiltered vibration signal, and the DC bias voltage. Portable test equipment or analyzers can be connected to this output without disturbing other system outputs.

Fault Detection:

On board fault detection circuitry continuously monitors the transducer for normal operation. If a fault occurs, the output current is reduced to <2 mA to indicate the fault to the readout system. A green LED on the front of the unit is turned off to provide a local indication of the fault.
