Product Introduction
The Bently Nevada 3500/50M (Part Number: 286566-02) is an advanced two-channel tachometer module designed for deployment within the industry-standard 3500 Machinery Protection System. Engineered to monitor critical rotational parameters such as shaft speed, rotor acceleration, and zero speed, this module compares measured values against programmable alarm setpoints to protect high-speed turbomachinery like steam turbines, gas turbines, and large compressors. Utilizing high-resolution digital signal processing, the 3500/50M accepts inputs from proximity probes or magnetic pickups, providing reliable speed indication, phase reference data for balancing, and critical shutdown interlocks to prevent catastrophic mechanical failures.
Frequently Asked Questions
⚡ What is the primary function of the 3500/50M tachometer module?
It continuously monitors rotational speed, acceleration, and reverse rotation, comparing them against user-defined alarm setpoints to trigger machinery protection actions.
🔌 What types of sensors can be connected to this module?
It accepts input signals from standard eddy-current proximity transducers (proximitors) or magnetic speed pick-up sensors.
⚙️ How does the module integrate with plant control and monitoring software?
It communicates system data via the 3500 rack backplane to relay modules, gateway communication modules, and the 3500 Rack Configuration software for remote diagnostics.
