Product Overview

Brand: AI-Tek Instruments (Airpax). Condition: New & Original. Factory Warranty: 12 Months.

Key Specifications & Data

Thread Length: 3.000 in (76.20 mm). Sensor Length: 4.125 in (104.77 mm). Standard Output: 63 V (P-P). Guaranteed Output: 4.9 V (P-P). DC Resistance: 250 ohms max. Operating Temperature: -55 to +107°C.

Installation & Setup

This passive sensor requires no external power. Install using the standard M18 mount. Ensure the target gear has clean teeth for a strong signal. The sensor generates its own AC voltage when near a rotating gear.

Compatibility Notes

Works with most turbine and gearbox systems. Ideal for monitoring RPM on large diesel engines. Compatible with legacy monitoring systems from General Electric and Westinghouse. Perfect for high-temperature environments.

Packaging Contents

One Passive Speed Sensor. One lock washer and one mounting nut. No certification paperwork is included in the box.

Shipping & Warranty

We ship globally via Fedex UPS and DHL. Your order is protected by a 12-month manufacturer warranty against defects.

Industrial Applications

Monitor turbine overspeed in power generation plants. Track engine RPM on marine propulsion systems. Provide critical speed data on railroad traction motors. Use in high-vibration environments on compressor stations.

Solving Industry Problems

Provides reliable data in extreme heat where other sensors fail. Its passive design means it works in remote locations without power. Durable construction resists corrosion in offshore oil and gas applications. Delivers a strong signal even with minor gear imperfections.
