Description of Equipment or Protective System
The Model TXA Non-Contact Position Transmitter is designed to provide a 4-20mA loop output signal proportional to the
distance between a target and the tip of a certified proximity probe which is transmitted to the non-hazardous area.
The Model TXR Non-Contact Vibration Transmitter is designed to provide a 4-20mA loop output signal proportional to
the radial vibration of a shaft or other machine part in relation to the location of the tip of a certified proximity probe.
The electronics are contained on three printed circuit boards (PCBs) housed in a plastic enclosure.
Power and signal connections are made at the terminals marked "POWER", at one end of the apparatus, and the remote
proximity probe is connected to the RF connector marked “PROBE” at the other end of the apparatus. An additional BNC
connector marked "DYNAMIC OUTPUT" also exists on the face of the apparatus but this is not to be used in the
hazardous area.
Additional connectors, not accessible to the customer are located behind the bottom cover. These are for the calibration of
the transmitter and are not to be used in the hazardous area.
