        Features:

        • Integrated Proximitor Sensor conditions signals directly without requiring an external driver unit.
        • Non-interacting zero and span potentiometers enable simplified external loop calibration.
        • Potted enclosure design provides protection in environments up to 100% condensing humidity.
        The Bently Nevada 991-01-XX-01-CN MOD 284318-01 is configured as a 2-wire, loop-powered axial displacement transmitter with a 4 to 20 mA signal output and 35 mm DIN-rail or bulkhead mounting options.

        Engineered to operate with 3300 NSv proximity probes, this unit converts shaft axial movement into standard industrial current loop signals for direct input into machinery control systems.

        Proper probe gap setup is critical for thrust measurements, and dynamic diagnosis via the PROX OUT terminal requires an isolated interface when using AC-powered test tools.

        The 991-01-XX-01-CN MOD 284318-01 is an active stock item supplied by Apter Power, with worldwide delivery and technical support available directly or through the original manufacturer (OEM).

        Description
        Bently Nevada 991-01-XX-01-CN MOD 284318-01 Thrust Transmitter provides direct axial position signal conditioning for machinery control systems without requiring external Proximitor units. By accepting inputs from a 3300 NSv proximity probe, it converts shaft displacement metrics into a proportional 4 to 20 mA loop-powered signal for continuous trend monitoring and alarm logic execution.

        Designed for original equipment manufacturers and industrial facilities, this transmitter simplifies installation on centrifugal air compressors, fans, and high-speed pumps. The module incorporates non-isolated PROX OUT terminals and a coaxial connector, allowing field technicians to access dynamic vibration and gap voltage signals for advanced diagnostic troubleshooting without disrupting the primary control loop.

        Built with a fully potted housing, the 991-01-XX-01-CN MOD 284318-01 delivers high resistance against 100% condensing humidity environments. It incorporates built-in Power-up Inhibit circuitry to eliminate voltage transient errors, non-interacting zero/span potentiometers for field calibration, and a Not OK/Signal Defeat circuit to prevent false machinery alarms.
