The 133442-01 is a 2-channel Tachometer Input/Output (I/O) Module with internal terminations. It is used with the 3500/50M Tachometer Module.
Speed Monitoring, Setpoint Alarming and Speed Band Alarming
Speed Monitoring, Setpoint Alarming and Zero Speed Notification
Speed Monitoring, Setpoint Alarming and Rotor Acceleration Alarming
The module accepts input from proximity probes or magnetic pickups to determine shaft rotative speed, rotor acceleration, or rotor direction. The module compares these measurements against user-programmable alarm setpoints and generates alarms when the setpoints are violated. The module can be configured to supply conditioned Keyphasor signals to the backplane of the 3500 rack for use by other monitors, eliminating the need for a separate, dedicated Keyphasor module in the rack. Bently Nevada 133442-01 stores critical operational history, including the highest speed, highest reverse speed, or the number of reverse rotations reached by the machinery (values can be manually reset).

Power Generation Industry
Monitors steam and gas turbine speeds to prevent catastrophic generator overspeed conditions.
Oil & Gas Upstream
Monitors shaft speed and reverse rotation of large compressors and water injection pumps on offshore platforms.
Petrochemical & Refining
Monitors speed status of critical flue gas expanders and blowers in Fluid Catalytic Cracking Units (FCCU).
Pipeline Transportation
Monitors real-time speed of gas turbine-driven compressor units along long-distance natural gas pipelines.
Steel & Metallurgy
Monitors startup acceleration and rotation direction of blast furnace blowers and large rolling mill motors.
Mining & Mineral Processing
Monitors low-speed and zero-speed status of massive ball mills, conveyor drives, and crushers.
Ensure compliance with sensor explosion-proof and grounding standards during wiring, and never route sensor cables alongside power lines to prevent interference. Although the module supports live hot-swapping, verify that the rear rack pins are not bent before insertion, and insert or remove the module smoothly and vertically to avoid damaging the backplane interface from lateral force.
