Industry Applications
The AI-TEK 70085-1010-428 excels in applications where temperature extremes cause other sensors to fail. Common uses include turbine speed monitoring, conveyor belt tachometry, and motor RPM sensing in steel mills or power plants. Its 24 V P-P output provides a strong signal even over long cable runs, reducing noise issues.
Installation & Setup
Installation is straightforward with the 3/8-24 threaded body. The white lead is positive; connect to your monitoring system's input. Ensure the sensor length of 1.94 in and thread length of 1.5 in match your mounting hole depth. Use the supplied wires for termination—no special connectors required.
Maintenance & Reliability
With a wide temperature rating and robust construction, the AI-TEK 70085-1010-428 requires minimal maintenance. The 125 ohm DC resistance ensures low power dissipation, while the 21 mH inductance provides consistent signal generation. Regular visual inspection of the lead wires for damage is recommended in high-vibration environments.
Troubleshooting & Common Issues
Signal dropout often stems from incorrect gap adjustment. Ensure the sensor face is within 0.5 mm of the target gear tooth. If no output is present, verify the white lead connection and measure DC resistance—if above 125 ohms, the coil may be damaged. The AI-TEK 70085-1010-428's 2.0 V guaranteed output at low speeds helps detect issues early.
