The TR01 Acceleration In/Acceleration Out Transmitter is available in either "Peak" or "True RMS" signal detection versions. The TR01 is compatible with all voltage output accelerometers, and provides a 4-20 mA output proportional to the overall measurement. Each unit provides constant current power for the accelerometer, 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 g's with a 100 mv/g Input. CSA and UL Class 1, Div 2, B-D Approved.
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.
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 are available with the Monitor version
Alarms - The TR01-M 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.
