Function:Non-contact detect rotating gear teeth. Convert mechanical rotation into digital pulse signal.Provide real-time rotating speed and key phase reference signal for overspeed protection and vibration spectrum analysis.

Installation:Thread mounted on bearing housing,adjust air gap between probe and gear tooth within 1.5mm.Connect shielded cable to MMS6823 monitor terminal.

Interface:

‑Stainless steel threaded probe body

‑10m integrated shielded signal cable

‑Terminal wiring port for TSI speed module

Circuit feature:Built-in high performance hall chip,double shielded cable design,resist oil,high temperature and electromagnetic interference,stable pulse output at low rotating speed.

Feature:EPRO PR9373 hall effect speed & keyphase probe,10m cable version. Long cable design for long-distance wiring. Common faults:cable breakage,hall element damage,incorrect installation gap. Confirm full model before replacement.

Diagnostic:Sensor fault leads to missing pulse signal,losing speed or keyphase signal,trigger TSI overspeed alarm.

Built‑in function

PR9373/010-011 captures shaft speed and keyphase pulse signal for rotating machinery protection,widely used for power plant TSI spare replacement.

Product Brief

PR9373/010-011 belongs to EPRO hall effect speed sensor family,10m cable hall probe for speed and keyphase measurement. Verify compatibility with MMS speed monitor before ordering. Check cable continuity and pulse output during commissioning. Widely applied for steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
