Overview Manuals Specifications

Features:

  • Bently Nevada 990 series shaft riding probe assembly for direct measurement of shaft vibration and position
  • Spring-loaded mechanism maintains continuous contact with rotating shaft surface for accurate monitoring
  • Designed for applications where non-contact proximity probes cannot be installed or are impractical
The 990-05-70-02-00 provides essential mechanical sensing functions critical to the entire monitoring path, serving as the primary interface between the rotating shaft and the monitoring system, directly affecting the proper, normal operation of the overall protection system. One 990-05-70-02-00 assembly is required per measurement point, mounted on the machine casing with the roller or pad contacting the shaft surface.

For applications requiring reliable measurement on low-speed shafts or in high-temperature areas, the 990-05-70-02-00 incorporates sealed bearings and wear-resistant contact surfaces for extended service life. In addition to standard vibration measurement, the mechanical design of the 990-05-70-02-00 allows operation in environments where electrical interference or physical constraints preclude the use of eddy current probes.

The 990-05-70-02-00's mechanical design ensures reliable operation in demanding industrial environments. Using precision bearings and robust housing construction, the assembly maintains accurate shaft tracking over extended periods. The spring-loaded mechanism of the 990-05-70-02-00 compensates for shaft runout and thermal growth while maintaining continuous contact.

The 990-05-70-02-00 Bently Nevada Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Bently Nevada 990-05-70-02-00 Vibration Transmitter is designed for industrial machinery monitoring, providing precise vibration measurement for compressors, pumps, fans, and motors. It accepts input from a single 3300 NSv non-contacting proximity probe with extension cable and outputs a proportional 4–20 mA signal for machinery control systems, supporting alarm and logic functions.

This transmitter features an integrated Proximitor sensor, eliminating the need for external signal conditioning units. Its non-isolated PROX OUT and COM terminals and coaxial connector allow simultaneous dynamic vibration and gap voltage diagnostics. Non-interacting zero and span potentiometers under the transmitter label simplify loop calibration without affecting other settings.

Additional features include a Test Input pin for quick loop signal verification, a Not OK/Signal Defeat circuit to prevent false alarms from faulty probes or loose connections, and potted construction for high-humidity environments, including up to 100% condensing conditions. The transmitter’s compact design ensures compatibility with 3300 NSv probes, allowing installation in tight spaces typical of centrifugal air compressors.
