Proximity Transmitters PROXIMITY PRODUCTS TXR5521 RPM Transmitter Combined Probe Driver & Signal Conditioner for RPM or Phase Reference Features • • • • 4-20 mA proportional to shaft RPM Sensing to 177°C with PP Series Probe Dynamic output for vibration phase reference used in analysis Full scale range from 5 RPM to 300,000 RPM The Model TXR5521 is a 2-wire transmitter operating on a nominal power of +24 Vdc. The unit operates with an eddy current proximity probe to sense a keyway or gear teeth on a rotating shaft and provides a 4-20 mA output proportional to shaft RPM. The transmitter is factory preset by complete model number. The full scale RPM can be set from 5 to 300,000 RPM and pulses/revolution set from 1 to 99. The minimum RPM resolution is a function of the number of pulses/revolution: the number of pulses per revolution times the maximum RPM desired must be less than or equal to 300,000. Specifications Function: Loop powered transmitter operates with a non-contact proximity probe/cable to convert shaft rotation in revolutions per minute (RPM) to a proportional 4-20 mA output signal. Probe Gap: 1.25 mm [50 mils]. Temperature Limits: -40° to 85°C Isolation: 500 Vrms, circuit to case Proximity Probe/Cable: Available for any standard probe cable combination, Can be factory-calibrated for any probe and/or cable. Pulses/Revolution: 1 to 99 pulses/ revolution (300,000 pulses/minute maximum). See How To Select for factory preset options. RPM Range (4-20 mA output): From 5 to 300,000 RPM. See How To Select for factory preset options. Loop Supply Voltage (Vs): 17 volts to 30 Vdc Standard Target Material: 4140 steel shaft keyway or gear teeth. Custom calibration available for other materials, please consult factory. Test Output (AC & DC): Access: Via terminals and BNC Isolation: 10K ohm from 4-20 mA loop Sensitivity: 7.87 mV/micron (200mV/mil) Maximum Load Resistance (RL): RL=50 x (Vs -17.0) Ohms Housing: Polymer internally coated for RFI/EMI protection.
