Functional Description
The 991-25-50-02-00 thrust transmitter delivers accurate thrust position measurements with integrated diagnostics. Its power‑up inhibit circuit prevents transient signal errors, while the Not OK/Signal Defeat circuit eliminates false alarms from faulty probes or loose connections. Potted construction ensures durability in high‑humidity environments, and compatibility with 3300 NSv probes allows installation in tight spaces with minimal clearance.
Applications and Compatibility
Compatible with Bently Nevada 3300 NSv proximity probes.
Ideal for centrifugal air compressors and machinery with limited clearance.
Provides thrust position monitoring in both normal and counter directions.
Suitable for predictive maintenance and machinery protection programs.
Designed for harsh industrial environments with condensing humidity conditions.
