991-06-70-01-CN | Bently | Vibration Transmitter NEW FedEx or DHL or UPS

Bently Nevada is a global leader in industrial asset condition monitoring and protection, specializing in vibration, pressure, and speed measurement solutions for critical machinery. Founded in 1956 by Don E. Bently, the company pioneered eddy-current proximity probes, revolutionizing rotor dynamics monitoring. Acquired by GE in 2002, Bently Nevada operates in over 50 countries, serving industries such as oil & gas, power generation, and mining. Its product portfolio includes sensors, monitoring systems like the 3500 Series, diagnostic instruments, and predictive maintenance software such as System 1. With over 25,000 customers worldwide, the company combines more than 60 years of expertise with cloud-connected solutions to enhance asset reliability and operational safety.

The Bently 991-06-70-01-CN is a thrust/axial displacement transmitter designed for monitoring axial movement in rotating machinery, particularly in centrifugal air compressors, small pumps, motors, and fans. It provides a 4-20 mA proportional output signal corresponding to the relative thrust displacement, making it suitable for integration into control systems for machine protection and logic operations. This model is part of Bently Nevada's 991 series, featuring two-wire loop-powered operation and compatibility with 3300 NSv proximity probes and matched extension cables (available in 5m and 7m lengths). Key functionalities include dynamic vibration and gap voltage outputs for diagnostics, non-interactive zero/span adjustments, and built-in fault detection to prevent false alarms due to probe failures or loose connection.

The 991-06-70-01-CN variant is optimized for 0.6 mm (±0.3 mm) axial displacement measurement and includes a 7-meter (23 ft) cable system. It supports DIN rail or panel mounting, making installation flexible for industrial environments. The transmitter is designed for high-humidity conditions (up to 100% condensation) and features a rugged, potted construction. It is commonly used in OEM applications where a simple, reliable axial position signal is required for machine control systems. Additional features include test input pins for loop verification and compliance with CSA, ATEX, and ABS marine certifications for hazardous area installation.
