Transmitter Sheet in PDF Format
Description:
The CMCP545 Position Transmitters are compatible with
any proximity probe input, and they provide a 4-20 mA output proportional to the
overall measurement. Each unit processes the signal to determine position,
and outputs a 4-20 mA dc current that is proportional to a user specified
range such as +/- 20 mils. Combining transmitters with an
existing PLC or DCS system results in a high density, low cost monitoring system.
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.
Alarms:
The CMCP545 Position Transmitters do
not have any alarm features. For alarms we have the CMCP545A
Position Monitors
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
position transmiter that accepts input from a 100 mV/mil proximity probe, with a Full Scale of
+/- 20 mils,
specify Part Number: CMCP545-100-01.
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.
