Proximity Probe Transmitter

Trendsetter Model TXR (Radial) and TXA (Axial)
Specifications
Unless otherwise noted, all specifications are
specified at 21°C (70°F), +24 Vdc power
supply, gap set to 1.27 mm (50 mils) and
using Metrix AISI 4140 steel target.
Operating Temperature Range:
-40°C to 85°C (-40°F to 185°F)
Operating Humidity Range:
95% non-condensing, external environmental protection is required

This new Trendsetter transmitter is a 2-wire looppowered transmitter combining an eddy current
probe driver and a signal conditioner in a single
package. It provides a 4-20 mA output proportional
to overall peak to peak displacement and operates
with Metrix probes and extension cables as well as
4 major probe systems. A DC voltage output and
dynamic signal is available at the BNC connector.
The TXR Transmitter is designed for radial
vibration while the TXA Transmitter is designed for
axial position vibration.

Power Requirements:
•t 17 to 30 VDC with a maximum start up current of
23 mA (-40°C to 85°C)
•t Maximum loop resistance is determined by RL =
50 (Vs-17) ohms
Frequency Response:
•t 5 Hz to 5 kHz +0, -3 dB pk-pk vibration
•t 0 Hz to 20 Hz +0, -3 dB position
Linear Range:
•t 0.5 to 2.0 mm (20 to 80 mils); (8 mm probe)
•t 0.5 to 4.0 mm (20 to 160 mils); (11 mm probe)
Buffered Output:
•t 7.87 V/mm (200 mV/mil) +/- 5% when calibrated
as a system, +/- 12% including interchangeability
error when measured in 0.25 mm (10 mils) increments over linear range
•t 3.94 V/mm (100 mV/mil) +/- 5% for 11 mm probes
when calibrated as a system, +/- 12% including interchangeability error when measuredin 0.25 mm
(10 mils) increments over the linear range
•t 0 Hz to 3 kHz +0, -3 dB
Note: The buffered output is intended for local
diagnostics only and will not support loads that are
less than 100k ohms.
4-20 mA Output:
•t 4 mA +/- .1 mA with no input vibration
•t 4 mA +/- .2 mA @ -40°C to 85°C with no input
vibration
•t 20 mA +/- .5 mA @ -40°C to 85°C with full scale
input vibration
•t < 3.6 mA indicates “Not OK” condition
