Product Description
991-06-XX-01-00 / MOD 169955-01 Dual-Direction Axial Displacement Thrust Transmitter for Centrifugal Compressor Shaft Protection
The Bently Nevada 991-06-XX-01-00 (MOD 169955-01) is a 2-wire thrust transmitter that converts 3300XL 8mm probe signals into a 4-20 mA loop for reliable axial displacement monitoring.
0.6-0-0.6 mm Range: High-precision bidirectional tracking to trigger DCS alarms before rotor collision.
3 Vdc @ 20 mils Elec Zero: Fast probe gap calibration via a standard multimeter.
MOD 169955-01 / 5m System: Exact OEM tuning for AISI 4140 steel, ensuring seamless drop-in replacement.
Tech Tip: Use a battery-powered meter on the PROX OUT port; unisolated AC instruments will cause false DCS trips.
Case: Successfully field-proven in centrifugal compressors with zero signal dropout.

Technical FAQs
What does the Bently Nevada 991-06-XX-01-00 169955-01 do?
The Bently Nevada 991-06-XX-01-00 169955-01 is built to watch axial shaft movement and pass the value to a PLC or DCS through a 4-20 mA signal. Its measuring range is 0.6 - 0 - 0.6 mm. You'll see this model on compressors, pumps, and plenty of other rotating machines where thrust monitoring matters.
Why order the MOD 169955-01 version instead of another 991?
The MOD 169955-01 code points to a particular factory build. Although another Bently Nevada 991 Thrust Transmitter may look almost the same, that doesn't always mean it behaves the same in service. Sticking with the identical modification is usually the easiest way to avoid replacement headaches.
What probe setup goes with 991-06-XX-01-00 169955-01 transmitter?
For this version, the intended match is a Bently Nevada 3300XL 8mm probe plus a 3300XL extension cable with a total 5 meters system length. Calibration is referenced to AISI 4140 steel.
How is 991-06-XX-01-00 169955-01 normally installed?
Nothing complicated here. The transmitter mounts on a 35 mm DIN-rail and accepts +12 to +35 VDC. After checking the reference value and adjusting the probe gap, the unit is generally ready to go.
Anything to remember when using the PROX OUT port on the 991-06-XX-01-00 169955-01?
Yes. The PROX OUT connection shares a non-isolated ground, so plugging in a regular AC-powered oscilloscope isn't a good habit. Most engineers simply use a battery-powered tester or the Bently Nevada 122115-01 test adapter when checking the signal.
