Applications
The AI-TEK 70085-1010-174 Speed Sensor is ideal for monitoring rotational speed in kilns, conveyors, and turbine systems where ambient temperatures are extreme. Its robust design also suits engine testing and material processing equipment. In such scenarios, the sensor's high output voltage (55 V P-P) allows reliable signal transmission even with long cables, reducing noise issues.
Installation Guide
Install the sensor by threading it into a 3/8-24 threaded hole. Ensure the sensor tip is positioned close to the target gear or rotating element for optimal signal. The white lead is positive; connect carefully. Cable length of 60 inches provides flexibility for mounting. Avoid over-tightening to prevent thread damage.
Maintenance & Reliability
Although the AI-TEK 70085-1010-174 is built for rugged use, periodic inspection is recommended. Check the cable for abrasion, especially in high-vibration areas. Verify the sensor tip clearance ensures consistent signal. The wide temperature rating means less thermal stress, extending service life. Clean the sensor tip occasionally if exposed to debris.
Selection Guide
When selecting the AI-TEK 70085-1010-174, verify that your application's temperature range and thread size match. For assistance, contact PLC Source PRO (formerly ubest101) for technical support and ordering.
