Bently Nevada 991-06-70-03-00 Vibration Transmitter Sale

Product Introduction

The Bently Nevada 991-06-70-03-00 is a dedicated Thrust Transmitter for axial position monitoring in rotating machinery. This device accepts input from a single non-contacting 3300 NSv Proximity Probe and extension cable. It then translates that measurement into a standard 4-20 mA output signal. This output directly represents the target's axial position. Therefore, it is critical for predictive maintenance and machine protection systems. Specifically, this model features a full-scale option of 0.6-0-0.6 mm. It also includes a 7.0-meter (23.0 feet) system length option. Furthermore, the unit incorporates non-interacting zero and span adjustments. These adjustments simplify field calibration significantly.

Key Technical Specifications

The 991-06-70-03-00 operates within a linear range of 0.25 to 1.65 mm for Prox Out. This range makes it ideally suited for 0.6-0-0.6 mm current loop linear ranges. For the output stage, the device provides 4-20 mAdc over the specified full-scale range. It uses a standard 2-wire configuration for easy integration. In terms of performance, the loop accuracy typically stays within ±1.5% over the full scale range. This accuracy is rated from the TEST signal input to the voltage measured across a 250 Ω loop resistance. Additionally, the unit limits current at 23 mA typical. Meanwhile, the maximum loop resistance reaches 1,000 Ω including cable at 35 Vdc.

Power and Environmental Limits

This transmitter requires a +12 to +35 Vdc input at its terminal. For operating environments, the temperature range extends from -35°C to +85°C (-31°F to +185°F). In contrast, the storage temperature tolerances are broader, from -51°C to +100°C (-60°F to +212°F). Consequently, these wide limits ensure reliable performance even in harsh industrial conditions.

Mounting and Installation

The Bently Nevada 991 transmitter features a DIN rail mount for straightforward cabinet installation. Specifically, this model carries mounting option "03," which includes DIN clips and screws. This hardware makes attachment quick and secure. Furthermore, the unit includes a Not OK/Signal Defeat safety feature. For example, the signal output drops below 3.6 mA within 100 µs of a Not OK condition. Likewise, the output restores within 0.1 seconds after the condition clears. Therefore, this rapid response protects downstream monitoring systems effectively.

Dimensional Data and Weight

This transmitter is both compact and lightweight in design. Its total weight is just 0.43 kg (0.9 lbm). As a result, this low weight minimizes stress on the DIN rail. It also simplifies handling during installation or routine maintenance.
