Industry Applications
The AI-TEK 70085-1010-007 Speed Sensor is ideal for monitoring rotating machinery in oil and gas, power generation, and heavy manufacturing. For example, in a gas turbine application, the sensor's high output voltage (21 V P-P) ensures accurate speed feedback even with long cable distances to the control room. The wide temperature range (-55 to +107°C) allows placement near hot engine compartments without signal degradation. In steel mills, the 3/8-24 thread mounting simplifies retrofit into existing bearing housings.
Installation & Setup Guidance
Proper installation of the AI-TEK 70085-1010-007 maximizes its lifespan and accuracy. Mount the sensor so that the sensing face is perpendicular to the target gear tooth or magnetic pickup. Maintain an air gap consistent with the guarantee point specifications. The pre-attached wires (white positive, black negative) simplify electrical connections; ensure shield termination per your control system grounding plan. Avoid overtightening the 3/8-24 threads to prevent housing stress. The sensor length (1.252 in) and thread length (0.812 in) provide a compact footprint suitable for tight spaces.
Maintenance & Reliability
The AI-TEK 70085-1010-007 is a passive device with no active electronics, meaning no scheduled maintenance for internal components. However, periodic inspection of the sensing face for debris or metal particle buildup is recommended in dusty environments. Check the lead wires for cracks or abrasion at the termination point every 6 months. The robust construction ensures long service life even in high-vibration applications, reducing unplanned downtime and replacement costs.
Selection Guide & Purchasing Advice
Before purchasing the AI-TEK 70085-1010-007, verify that your target gear material and tooth geometry are compatible with magnetic speed sensors. Confirm the required output voltage level for your controller input; the standard 21 V P-P output is suitable for most PLC and DCS input modules. If your application involves extreme temperatures above +107°C, consider a high-temperature variant.
