Quick Detail

Description

The 990-05-70-01-00 is a high-performance, loop-powered Vibration Transmitter from Bently Nevada, engineered to provide reliable, continuous monitoring of machinery health. This robust transmitter converts raw vibration signals from compatible proximity probes into a standardized 4-20 mA output signal, which is directly proportional to the measured vibration level. This seamless signal conversion enables easy integration with Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), and other plant-wide monitoring networks, facilitating real-time equipment protection and predictive maintenance strategies. Designed for simplicity and durability, this industrial vibration transmitter is an ideal solution for monitoring critical assets such as pumps, motors, fans, and compressors where continuous vibration data is essential for operational safety and efficiency.

This Bently Nevada vibration transmitter is distinguished by its exceptional ease of installation and configuration. It features a compact design with dimensions of 10x7.4x6cm and a lightweight of 0.5kg, allowing for flexible mounting in control panels or near machinery using its standard 35 mm DIN rail clips. The device requires no external power supply, operating as a 2-wire loop-powered transmitter, which drastically simplifies wiring and reduces installation costs. It is preset to monitor a standard vibration measurement range of 0-5 mils peak-to-peak (0-125 µm pp), corresponding to a velocity range of 0-25.4 mm/s (0-1.0 in/s) peak, making it suitable for a wide array of general-purpose industrial rotating equipment. Its robust construction ensures reliable performance across a broad operating temperature range from -40°C to +85°C.

Applications

This Vibration Transmitter is primarily deployed for continuous protection monitoring of mid-range industrial rotating equipment such as centrifugal pumps, electric motors, industrial fans, and blowers. Its preset 0-5 mils pp (0-125 µm pp) vibration range and 4-20 mA output make it ideal for integration into basic PLC or DCS-based machinery protection systems, providing a simple, reliable signal to trigger alarms or automatic shutdowns before excessive vibration leads to mechanical failure, thus safeguarding critical process equipment in water treatment plants, commercial HVAC systems, and general manufacturing facilities.

Thanks to its compact, DIN-rail mountable design and 2-wire loop-powered operation, the transmitter is perfectly suited for retrofitting into existing control panels and cabinets with limited space and wiring complexity. Its broad operating temperature range of -40°C to +85°C allows it to function reliably in non-climate-controlled environments like pump houses, compressor stations, and outdoor industrial enclosures, providing robust condition monitoring without the need for additional signal conditioners or power supplies, thereby reducing system cost and complexity for facility-wide monitoring networks.

The device serves as a fundamental building block for cost-effective predictive maintenance programs. By delivering a stable, linear 4-20 mA signal proportional to overall machine vibration, it enables plant personnel and maintenance systems to track equipment health trends over time. Its high supply sensitivity (less than 0.05% per Volt) ensures data accuracy is not compromised by electrical noise or voltage variations commonly found in industrial settings. This reliable performance makes it a trusted solution for monitoring auxiliary and balance-of-plant equipment in power generation, oil & gas, and chemical processing industries, where preventing unplanned downtime is crucial.

Specifications

Competitive Advantage

1.Simplified Installation and Seamless System Integration

The 990-05-70-01-00 Vibration Transmitter offers unparalleled installation ease with its 2-wire loop-powered design and standard 35 mm DIN rail clips. This eliminates the need for separate power wiring and complex mounting hardware, cutting installation time and labor costs by over 50% compared to traditional four-wire transmitters. Its direct 4-20 mA output provides plug-and-play compatibility with virtually all industrial control systems (DCS, PLC), enabling rapid deployment and integration into both new and existing machinery protection systems without requiring additional signal converters.

2.Exceptional Operational Stability and Measurement Accuracy

Engineered for reliability, this transmitter delivers outstanding signal integrity in challenging electrical environments. Its extremely low supply sensitivity of less than 0.05% per Volt ensures that the output vibration signal remains accurate and unaffected by common power supply fluctuations. Combined with a calibrated linear range of 0-25.4 mm/s, it provides consistent, repeatable measurement data essential for effective trend analysis and predictive maintenance, giving users confidence in the reliability of their condition monitoring data for making critical operational decisions.

3.Robust Design for Broad Environmental Compatibility

Built to withstand demanding industrial conditions, the transmitter operates reliably across a wide temperature range of -40°C to +85°C, making it suitable for both indoor and outdoor applications without requiring protective enclosures. Its compact, rugged housing (10x7.4x6cm, 0.5kg) ensures durability in high-vibration areas. The inclusion of a long system length cable (7.0 meters) and a standard 3/4-14 NPT plug provides a complete, ready-to-use package that simplifies procurement and ensures a secure, professional installation in diverse industrial settings.
