Quick Detail

Description

The 990-05-50-01-05 Vibration Transmitter is a high-precision, loop-powered industrial solution engineered by Bently Nevada for continuous machinery protection. This advanced vibration transmitter is specifically designed to interface with proximity probe systems, converting raw vibration data into a standardized 4-20 mA signal. As a critical component in industrial monitoring, the 990-05-50-01-05 model allows for the seamless integration of vibration levels into Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC). By utilizing this vibration transmitter, plant operators can achieve real-time insights into the mechanical health of rotating assets, ensuring that any deviation from normal operating parameters is detected immediately.

The 990-05-50-01-05 model is characterized by its preset full-scale range of 0-5 mils pp (0-125 μm pp), making this vibration transmitter ideal for monitoring displacement on fluid-film bearing machines. This specific Bently Nevada vibration transmitter configuration features a 5.0-meter system length, providing the necessary flexibility for sensor-to-transmitter connectivity in complex layouts. Furthermore, the 990-05-50-01-05 is built to withstand harsh industrial environments, featuring a robust housing and 35 mm DIN rail clips for secure mounting. The integrated 4-20 mA loop-powered design of this vibration transmitter eliminates the need for external power supplies at the mounting location, significantly reducing wiring costs and installation complexity.

Applications

The 990-05-50-01-05 Vibration Transmitter is primarily utilized for the continuous condition monitoring of medium-sized rotating machinery, such as centrifugal pumps, industrial fans, and small compressors. Its calibrated 0-5 mils peak-to-peak measurement range is specifically optimized for tracking shaft displacement in fluid-film bearings. By providing a direct 4-20 mA output to a PLC or DCS, it serves as a frontline defense system, allowing for automated alarms or emergency shutdowns when vibration levels exceed safe operational limits, thereby protecting high-value assets from mechanical damage.

In the power generation and wastewater treatment sectors, this vibration transmitter is frequently applied to auxiliary equipment and balance-of-plant machinery. The compact 35 mm DIN rail mounting and 2-wire loop-powered architecture make the 990-05-50-01-05 an excellent choice for retrofitting existing control cabinets where space is at a premium. Its ability to operate reliably across a wide temperature range—from -40°C to +85°C—allows it to be installed in non-climate-controlled environments like outdoor pump stations or remote industrial enclosures without compromising data integrity.

The maritime and hazardous area certifications (ATEX/CSA/ABS) expand the application of the 990-05-50-01-05 to offshore platforms, tankers, and chemical processing plants. It is used to monitor critical propulsion components and large motors in environments where explosive gases or corrosive salt air may be present. By delivering a stable, linear signal proportional to vibration, this transmitter enables maintenance teams to implement data-driven predictive maintenance strategies, identifying trend shifts early to schedule repairs during planned outages rather than reacting to unplanned failures.

Competitive Advantage

1. Superior Integration and Installation Efficiency

The 990-05-50-01-05 stands out with its 2-wire, loop-powered design, which simplifies the electrical architecture by combining power and signal into a single pair of wires. This significantly reduces the cost of copper and labor during installation. Equipped with standard 35 mm DIN rail clips, the transmitter can be mounted instantly in industrial panels, offering a much faster deployment cycle compared to traditional transmitters that require specialized brackets or bulky enclosures.

2. High-Precision Measurement in Harsh Environments

With a supply sensitivity of less than 0.05% per Volt, this vibration transmitter ensures that electrical noise and voltage ripples from the plant power grid do not affect the accuracy of the vibration readings. Its linear range is finely tuned for 0-5 mils pp, providing high-resolution data for critical shaft vibration. The device’s resilience is further proven by its wide operating temperature tolerance and various hazardous area approvals (ATEX/CSA), ensuring long-term stability where lesser transmitters might drift or fail.

3. Industry-Standard Reliability and Certification

As a Bently Nevada product, the 990-05-50-01-05 benefits from decades of expertise in machinery protection. The inclusion of ABS maritime approval and ATEX Zone 0/2 ratings makes it a "universal" solution for global industrial applications. The "Original New Factory Sealed" packaging ensures that every unit arrives with the highest quality standards, providing users with a trusted, maintenance-free solution for monitoring essential rotating equipment in the most demanding industries.
