Bently Nevada 990-05-70-02-00 Vibration Transmitter for Machinery Protection

The 990-05-70-02-00 operates as a vibration transmitter within Bently Nevada machinery protection systems. This unit converts probe signals into a standardized current output for control systems. Consequently, reliability engineers gain continuous vibration data without dedicated monitoring racks.

Technical Specifications Overview

This transmitter combines a sealed housing with rugged industrial construction. Moreover, its parameter set helps engineers plan mounting positions and loop wiring accurately.

Interface and Signal Connection Details

This unit connects through a two-wire loop output cable. Therefore, technicians achieve simple wiring inside crowded junction boxes. The transmitter converts vibration signals into a standardized 4–20 mA output. In addition, it draws 24 V DC directly from the loop supply.

Physical Characteristics and Mounting

The device measures roughly 100 mm wide and 75 mm high. Furthermore, its 60 mm depth suits compact machine-side enclosures. It weighs about 0.6 kg. Consequently, it adds minimal load to bracket assemblies. Installation uses a bracket or panel mount, then technicians tighten the retaining hardware.

Operational Role and Maintenance

Engineers apply this transmitter for continuous vibration trending and alarm generation tasks. Meanwhile, front-panel indicators show live signal status during troubleshooting. The unit holds no battery or capacitor for energy storage. Thus, it avoids periodic cell replacement work. Instead, it relies entirely on the loop supply for power.
