Product Details
The Bently Nevada 3500/53-03-01 Electronic Overspeed Detection System is a high-speed tachometer and protection module engineered for critical rotating machinery. Designed to comply with API 670 and 612 standards, this three-channel system configuration monitors turbine and compressor rotational speeds, processing proximity or magnetic pickup inputs to execute rapid shutdown logic during overspeed events.
Input Processing and Speed Measurement
The module accepts transducer input signals spanning a voltage range of +10.0 V to -24.0 V, supporting input frequencies up to 20 kHz with a maximum full-scale range of 99,999 rpm. It features selectable manual or automatic signal triggering thresholds and user-adjustable hysteresis to eliminate false speed counts caused by electrical noise or shaft runout.

Redundancy and Voting Configuration
The -03 suffix configuration provides a three-channel setup designed to operate in a 2-out-of-3 voting architecture, which ensures that single-fault conditions will neither cause missed protection trips nor spurious machine shutdowns. Front-panel LEDs provide immediate visual verification of channel status, OK conditions, test modes, and communication links with the 3500 rack framework.
Frequently Asked Questions
