Product Overview

The EPRO Emerson PR9376/010-011 is a non-contact Hall effect speed and proximity sensor designed for critical turbomachinery applications. Engineered for high-reliability pulse detection, speed monitoring, and zero-speed sensing, it is widely utilized across steam turbines, gas turbines, hydro turbines, compressors, industrial pumps, and large fans.

Operating on a 10 to 30 V DC power supply at a maximum current consumption of 25 mA, the PR9376/010-011 detects magnetic soft iron or steel spur wheels and involute gearing to generate 1 AC cycle per revolution or gear tooth. Featuring a stainless steel sensor body, PTFE cable assembly, IP67 ingress sealing, and a lightweight net sensor weight of 210 grams (7.4 oz), this sensor supports high-frequency rotational speed monitoring up to 12 kHz (720,000 cpm) across demanding operating environments.

Core Technical Advantages

  • High-Speed Signal Acquisition: Delivers continuous speed sensing up to 12 kHz (720,000 cpm) with ultra-fast signal rise/fall times of 1 µs.
  • Rugged Environmental Sealing: Constructed with a stainless steel body, PTFE cabling, and IP67 ingress protection to withstand wet or harsh plant conditions.
  • Flexible Field Wiring & Powering: Operates on a wide 10–30 V DC input range with a high output signal (>10 V high / <1 V low at 12 V DC into a 100 kΩ load).
  • International CE Compliance: Fully compliant with European Directives 2014/30/EU (EN 60947-5-2), 2014/35/EU, and 2011/65/EU (EN 63000 RoHS).

Installation & Gap Calibration Guide

  • Target Alignment & Setup: Position the sensor tip perpendicular to the spur wheel or involute gear trigger mark. Ensure target material is magnetic soft iron or steel (non-stainless).
  • Air Gap Calibration: Set the installation clearance gap precisely according to gear module size—1.0 mm for Module 1 targets or 1.5 mm for Module ≥2 targets.
  • Wiring & Power Connections: Connect the 10–30 V DC supply observing correct polarity, and ensure total load resistance remains below 400 ohms for optimal pulse generation.
