  • Buffered Transducer Output

  • Filter Option

Approved


Description:
 The CMCP-530 Vibration Velocity transmitters are compatible with piezo, voltage output accelerometer and velocity transducer inputs, they provide a 4-20 mA output proportional to the overall measurement. Each unit provides power for the associated transducer, processes the vibration signal to determine overall amplitude, and outputs a 4-20 mA dc current that is proportional to a user specified range such as 1.0 in/sec RMS. Combining transmitters with an existing PLC or DCS system results in a high density, low cost vibration monitoring system. When specified with the alarm feature (CMCP-530A), the unit functions as a complete single channel monitor that includes alert and danger alarms, and output relays.

 

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 like SKF-CM's MicrologTM 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 red LED on the front of the unit is turned on to provide a local indication of the fault.

 

Filters:
 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.

 

Displays And Assemblies:
Various display options, NEMA and explosion-proof enclosures, and assembled multi-channel systems are available. Consult your sales representative.

Ordering Example:

To order a standard velocity transmitter that accepts input from a 100 mV/g Accelerometer, such as the SKF-CM CMSS786, with a Full Scale of 1.0 in/sec with Peak Detection, specify Part Number: CMCP-530-100A-02P.

NOTES:

1.To order factory installed 4-pole filter modules, add the appropriate suffix to the basic part number:

Example: adding suffix -L500 specifies a 4-pole low-pass filter with a corner frequency of 500 Hz (30,000 cpm). Adding suffix - H40 specifies a 4-pole High-Pass filter with a corner frequency of 40 Hz (2400 cpm). Up to two filter modules may be specified. Filter modules can be field installed. If you are unsure about your filter needs, need higher order filters or a band-pass response, consult the factory or your regional sales office for assistance in specifying the correct option numbers.

2.The Full Scale option specified at order entry is used by the factory for initial calibration. However, several other ranges can be jumper selected in the field.

3.Transducer and Full Scale options not listed in the above table are available. Contact your sales representative.
