Product Overview

• PN: 24765-02-01
• Brand: Bently Nevada (Baker Hughes)
• Series: Magnetic Pickup Transducer
• Type: Passive Gear Tooth Speed Sensor

• Function: Inductive passive sensor that generates alternating voltage pulse signals when the gear tooth passes the probe tip. No extra excitation power is required. The pulse signal is sent to tachometer modules to calculate real-time rotating speed, overspeed alarm, zero-speed interlock and rotation direction judgment, serving as key speed signal source for turbomachinery safety protection system.
