Bently Nevada 991-06-70-01-00 Thrust Transmitter

Description

The Bently Nevada 991-06-70-01-00 Thrust Transmitter is designed primarily for original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, or fans. It provides a simple 4 to 20 mA proportional axial displacement (thrust) signal as input to machinery control systems. The transmitter accepts input from the 3300 NSv proximity probe and its matching extension cable. It conditions the signal into appropriate engineering units proportional to the shaft’s axial position and provides it as a standard 4 to 20 mA signal for machinery protection and logic.

Notable Features

• Integrated Proximitor Sensor (requires no external unit)
• Non-isolated “PROX OUT” and “COM” terminals with a coaxial connector for dynamic vibration and gap voltage signal output (for diagnostics)
• Non-interacting zero and span potentiometers for loop adjustment
• Test Input pin for quick verification of loop signal output
• Power-up Inhibit circuit to prevent signal errors due to line voltage transients
• Not OK/Signal Defeat circuit to prevent false alarms due to faulty proximity probes or loose connections
• Choice of DIN-rail clips or bulkhead mounting screws for easy installation
• Potted construction suitable for high humidity environments (up to 100% condensing)
• Compatible with 3300 NSv proximity probes, allowing installation in small areas with minimal clearance
