Proximity Probe Transmitter
This new Trendsetter transmitter is a 2-wire loop-
powered 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.
Features
• Cost effective alternative to
dedicated rack mount monitors
• Loop-powered
driver/transmitter
• Compatible with 4 major probe systems
• Easily factory calibrated to non-standard
shaft
material
• DIN Rail mounting (fl at mounting base
available) (P/N 9647)
• BNC for access to dynamic output and
probe
gap
• PBT plastic material
Machines using Shaft Monitoring
• Oil lubricated fl uid fi lm bearing machines:
-Centrifugal Pumps
-Turbo Compressors
-Steam and Gas Turbines
-Large Fans and Blowers
-Gear Box Shafts
-Generators
-Large Electric Motors
Specifi cations
Unless otherwise noted, all specifi cations are
specifi ed 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
Power Requirements:
•
17 to 30 VDC with a maximum start
up current of 23 mA (-40°C to 85°C)
• Maximum loop resistance is
determined by R
L
= 50 (V
s
-17) ohms
Frequency Response:
•
5 Hz to 5 kHz +0, -3 dB pk-pk
vibration
• 0 Hz to 20 Hz +0, -3 dB position
Linear Range:
•
0.5 to 2.0 mm (20 to 80 mils);
(8 mm probe)
• 0.5 to 4.0 mm (20 to 160 mils);
(11 mm probe)
Buffered Output:
• 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
• 3.94 V/mm (100 mV/mil) +/- 5% for
11 mm probes when calibrated as a
system, +/- 12% including
interchangeability error when measured
in 0.25 mm (10 mils) increments over the
linear range
• 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:
• 4 mA +/- .1 mA with no input
vibration
•
4 mA +/- .2 mA @ -40°C to 85°C
with no input vibration
• 20 mA +/- .5 mA @ -40°C to 85°C
with full scale input vibration
• < 3.6 mA indicates “Not OK”
condition
