Product Description

Bently Nevada 990-05-70-02-01 2-Wire Vibration Transmitter

The Bently Nevada 990-05-70-02-01 2-Wire Vibration Transmitter is a high-performance solution designed for continuous vibration monitoring of rotating machinery in industrial environments. Engineered to meet the demands of power generation, oil & gas, chemical processing, and manufacturing sectors, this transmitter ensures operational safety and reliability by providing real-time insights into equipment health. Its loop-powered 4–20 mA output with HART® 7 protocol enables seamless integration with control systems, allowing for remote diagnostics, configuration, and predictive maintenance via platforms like Emerson System 1™ Software.

The 990-05-70-02-01 delivers exceptional accuracy with a ±1% full-scale measurement range of 0–70 mm/s RMS (0–2.8 in/s) and a frequency response of 5–1000 Hz, making it ideal for detecting early signs of imbalance, misalignment, bearing wear, or mechanical looseness in turbines, compressors, pumps, and generators. The device operates flawlessly across extreme conditions, with an ambient temperature range of -40°C to +85°C (-40°F to 185°F) and IP67/NEMA 4X environmental rating, ensuring resilience against dust, moisture, and thermal stress. Its stainless steel (SS 316L) housing and vibration-tested design (surviving up to 20G acceleration) guarantee long-term durability in demanding environments, including offshore platforms and chemical plants.

A key advantage of the 990-05-70-02-01 is its intrinsic safety certification (ATEX/IECEx Zone 1/2, FM/CSA), enabling safe deployment in hazardous locations where explosive gases or vapors are present. The transmitter supports adjustable damping to filter noise from transient vibrations and includes continuous self-diagnostics for signal quality, sensor health, and calibration drift, reducing unplanned downtime. Configuration is simplified via HART communication, allowing technicians to adjust settings, update firmware, or analyze vibration data without process interruptions.

Installation flexibility is achieved through radial or axial mounting on machinery casings using a 1/2"-20 UNC threaded probe, ensuring direct contact for precise vibration capture.
