Descripción del producto

Bently Nevada 991-01-XX-01-CN/MOD: 284318-01 Vibration Transmitter

Product Overview

The 991 Thrust Transmitter is designed primarily for original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, or fans who require a simple 4 to 20 mA proportional axial displacement (thrust) signal as input to their machinery control system.

This 2-wire, loop-powered device accepts input from our 3300 NSv proximity probe and matching extension cable (available in 5 m and 7 m system length options). The transmitter conditions the signal into appropriate engineering units proportional to the shaft's axial position and provides it as a 4 to 20 mA industry-standard signal for input to control systems where machinery protection alarming and logic occurs.

Key Features

Integrated Proximitor Sensor requires no external unit
Non-isolated PROX OUT and COM terminals plus coaxial connector provide dynamic vibration and gap voltage signal output for diagnostics
Non-interacting zero and span potentiometers under transmitter label support loop adjustment
Test Input pin allows quick verification of loop signal output using a variable DC voltage source
Power-up Inhibit circuit eliminates signal errors due to line voltage transients
Not OK/Signal Defeat circuit prevents high outputs or false alarms due to faulty proximity probes or loose connections
Choice of DIN-rail clips or bulkhead mounting screws as standard mounting options
Potted construction for high humidity environments (up to 100% condensing)
Compatibility with 3300 NSv proximity probe allows transducer installation in small areas with minimal clearance

Technical Specifications

Parameter	Specification
Input	Accepts one non-contacting 3300 NSv Proximity Probe and extension cable
Power	Requires +12 to +35 Vdc input at transmitter terminal
Signal Output	4 to 20 mAdc over specified full-scale range in 2-wire configuration
Loop Accuracy	Within ±1.5% over specified full scale range (typical). Accuracy rated from TEST signal input to voltage measured across 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
Not OK/Signal Defeat	Signal output goes to less than 3.6 mA within 100 µs after Not OK condition. Signal output restored within 0.1 seconds after Not OK condition removed
Proximitor Sensor Output	Compatible with ungrounded, portable test equipment. Use 122115-01 Test Adapter for signal isolation with grounded, ac-powered test equipment

Important Notes

Probe Adjustment Critical

Probe adjustment and range are critical in thrust position measurements. Incorrect probe gap settings may prevent the transmitter from reaching full-scale in either normal or counter directions. For proper adjustment, follow instructions in the manual.

Application Limitations

Thrust transmitters have limitations compared to continuous monitoring systems. While capable of alarming on thrust position and non-OK checking, monitor functions such as Timed OK channel defeat, Danger Bypass, and Trip Multiply cannot be used. PLCs attached to thrust transmitters are not suitable for plant-wide diagnostic systems.

Signal Isolation Recommendation

The 991 Vibration Transmitter's PROX OUT coaxial connector provides a non-isolated dynamic transducer signal. While you can connect this signal directly to battery-powered or isolated test equipment, we strongly recommend using the 990/991 Test Adapter for signal isolation when using ac-powered test equipment to maintain machinery protection integrity.
