PR9376/010-011 | EPRO Hall Effect Speed & Keyphasor Sensor

Product Overview

PR9376/010-011 is a differential Hall-effect speed and keyphasor sensor from EPRO (Meggitt / Vibro-Meter family), built for non-contact rotational speed measurement and key phase reference signal generation on critical turbomachinery. It pairs perfectly with EPRO MMS6000 monitoring racks such as MMS6810, MMS6820 overspeed and vibration protection systems.

Adopting dual Hall-element half-bridge design with built-in DSP signal processing, this sensor outputs clean push-pull square pulses for speed monitoring, direction detection, standstill alarm and phase reference for balancing and spectrum analysis. It supports both ultra-low speed and high-speed measurement with sharp pulse edges and stable signal, widely used in steam turbines, gas turbines, generators, centrifugal compressors, pumps and blowers in power, oil & gas and petrochemical plants.

Key Benefits

• Differential Hall architecture, strong anti-interference, excellent EMI suppression
• Wide frequency bandwidth, reliable measurement from near zero speed up to high RPM
• Stainless steel probe body + PTFE insulated armored cable, resistant to oil, moisture and vibration
• IP67 ingress protection, suitable for bearing housing and harsh machine-side installation
• Short rise/fall time, low phase deviation, ideal for keyphasor and dynamic balancing
• Simple M18×1.5 threaded mounting, comes with lock nut and mounting accessories
• Compatible with standard ferromagnetic spur gears (module ≥1, ST37 soft steel target)
• Stable long-term operation for machinery protection and condition monitoring
