The CMCP540 Displacement Transmitter is compatible with all manufactures Eddy Probe or Proximity Probe Systems with a voltage output of 200 mv/mil and is available in English or Metric scaling. The CMCP540 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 0 to 5, 10, 15, 20 or 25 mils (0 to 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.

Custom Input and Output Calibrations are Available on Request.

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.

For applications that require monitoring specific frequency bands, optional high-pass and low-pass filters can be specified. These filters are modular and can be installed by the factory or in the field. Each module attenuates out-of-band signals at a rate of approximately 24 dB/octave. Corner frequencies from 2 Hz to 20 kHz may be specified. Filter modules may be cascaded to form higher order filters or to create a band-pass response. Filtering does not effect the buffered transducer output.

Alarms relays and trip multiply areavailable with the Monitor version

The CMCP500A Series Monitors havetwo 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 Relaycontacts are rated 5 Amps @ 30 Vdc or 250 Vac for resistive loads.

Relay contacts can be independentlyconfigured by the user for either Normally Open (NO) (Standard) or NormallyClosed (NC) operation. Relays are normally de-energized and can be configuredfor latching or non-latching (standard) operation. Latched alarms may be resetlocally or by remote contact closure.

Trip Multiply:
The monitorshave set point multiplication of 3X via contact closure (2X available). Toavoid tripping the alarms during machine start-up.
