Industry Applications
In high-vibration environments such as gas turbine monitoring, the AI-TEK 70085-1010-018 maintains accurate speed measurement despite mechanical stress. For example, in a petrochemical plant where ambient temperatures exceed 100°C, this sensor’s 107°C rating ensures continuous operation without degradation. The high output voltage (40 V P-P) prevents signal loss over distances exceeding 50 meters, reducing the need for signal conditioners and lowering total installation cost.
Installation & Setup Guidance
Mount the AI-TEK 70085-1010-018 using the 5/8-18 thread into a properly tapped hole. Ensure the sensor tip is positioned within 0.020–0.050 inches of the target gear or shaft teeth for optimal signal strength. Use the integral connector for wiring: connect Pin ‘B’ as the positive output and the housing as ground. Avoid running the sensor cable alongside high-voltage power lines to prevent electromagnetic interference. Apply thread-locking compound to resist vibration loosening.
Maintenance & Reliability
The 70085-1010-018 requires minimal routine maintenance. Periodically inspect the connector for corrosion and verify that the mounting clearance has not changed due to thermal expansion or mechanical wear. The sensor’s design includes no moving parts, reducing failure points. Its rugged construction and wide temperature tolerance contribute to an extended service life, minimizing replacement costs and unplanned downtime over the equipment’s lifecycle.
Selection Guide & Purchasing Advice
Before purchasing, verify that the thread size (5/8-18) matches your mounting point and that the target tooth or gear material is ferromagnetic for proper signal generation. The AI-TEK 70085-1010-018 is a direct replacement for many existing passive magnetic pickups with the same thread and output characteristics.
