Bently 991‑10‑70‑01‑00

Product Introduction: 991‑10‑70‑01‑00 is 991‑series integrated thrust‑position transmitter with built‑in proximitor conditioning‑circuit. It is factory‑calibrated for NSv transducer‑system total electrical‑length 7 meters. Full‑scale axial‑thrust‑displacement measuring‑range is ‑0.25 mm ~ +0.25 mm. It cooperates with 3300 NSv proximity‑probe plus matched extension‑cable of total 7‑meter electrical‑length. It converts shaft axial‑thrust‑collar gap‑variation signal into 4‑20 mA two‑wire loop‑output‑signal for DCS‑PLC‑system acquisition. It targets rotating‑machinery equipment which possesses small‑magnitude allowable axial‑thrust‑travel, realizes thrust‑position‑monitoring without rack‑mount separate proximitor hardware.

  • Mounting Method: 35 mm DIN‑rail clip‑mount or panel screw‑mount installation
  • Operating Temperature: ‑40 °C ~ +85 °C
  • Relative Humidity: 0‑95% RH non‑condensing
  • Startup‑Inhibition Function: Output maintains NOT‑OK fault‑status within 2‑3 seconds after power‑on Functional Features:
  1. Integrates complete proximitor‑signal‑conditioning‑circuit; NSv proximity‑probe system directly connects transmitter input terminals without external proximitor‑hardware.
  2. Two‑wire loop‑power architecture, single‑pair cable accomplishes power‑supply feeding and thrust‑position‑signal transmission, reduces field‑instrument‑wiring‑workload.
  3. Accessible zero‑point and span potentiometers support convenient on‑site field‑calibration‑adjustment.
  4. Dedicated test‑input pin enables loop‑function verification without physical NSv‑sensor‑hardware‑connection.
  5. Built‑in sensor‑loop fault‑detection function; upon probe open‑circuit, short‑circuit fault‑event, output locks to defined NOT‑OK fault‑current‑level to prevent control‑‑system receiving false axial‑thrust‑position‑readings.
