Description

Overview

The Bently Nevada 991-01-XX-01-00 Thrust Vibration Transmitter is designed to provide a 4 to 20 mA proportional signal for axial displacement (thrust) in machinery control systems. This device is ideal for OEMs of centrifugal air compressors, small pumps, motors, and fans. It converts the input from a 3300 NSv Proximity Probe into a standard 4-20 mA signal, which can be used for machinery protection and alarming. The transmitter is a 2-wire, loop-powered device, offering ease of integration into industrial automation systems.

Technical Specifications

Electrical

  • Input: Accepts 1 non-contacting 3300 NSv Proximity Probe and extension cable.
  • Power Requirements: +12 to +35 Vdc input at the transmitter terminal.
  • Signal Output: 4 to 20 mA DC over the specified full-scale range in a 2-wire configuration.
  • Accuracy: ±1.5% over the full-scale range (typical). Accuracy is rated from the TEST signal input to the voltage measured across a 250 Ω loop resistance.
  • Maximum Loop Resistance: 1,000 Ω, including cable, at 35 Vdc.
  • Current Limiting: 23 mA (typical).
  • Zero and Span: Non-interacting external adjustments for fine-tuning.

Signal Features

  • Not OK/Signal Defeat: Signal output drops below 3.6 mA within 100 µs after a Not OK condition occurs. It restores within 0.1 seconds after the issue is resolved.
  • Proximitor Sensor Output: Compatible with ungrounded, portable test equipment. For grounded, AC-powered test equipment, use the 122115-01 Test Adapter for isolation.
  • Output Impedance: 10 kΩ for a 10 MΩ load.
  • Linear Range: 0.25 to 1.65 mm (10 to 65 mils) for Prox Out. Suitable for 0.6-0.6 mm or 25-0-25 mils current loop linear ranges.
  • Incremental Scale Factor: 7.87 mV/µm (200 mV/mil) with ±6.5% typical interchangeability errors.
  • Temperature Stability: Incremental scale factor remains within ±10% from 0°C to +70°C (+32°F to +158°F).

Environmental

  • Transmitter Operating Temperature: -35°C to +85°C (-31°F to +185°F).
  • Storage Temperature: -51°C to +100°C (-60°F to +212°F).
  • Probe Operating Temperature: -52°C to +177°C (-62°F to +351°F).
  • Minimum Target Size: 9.5 mm (0.375 in) diameter.
