5.2 Electrical Wiring
- Access Terminal Head: Unscrew the cap of the sensor's terminal head to expose the wiring terminals.
- Connect Wires: Connect the sensor wires to your temperature controller or data acquisition system according to its specific wiring diagram. PT100 sensors typically use 2-wire, 3-wire, or 4-wire configurations. Ensure correct polarity and connection points as specified by your controller.
- Secure Connections: Ensure all wire connections are tight and secure to prevent intermittent readings or electrical issues.
- Close Terminal Head: Replace and securely tighten the terminal head cap to protect the wiring from environmental elements.

6. Operating Instructions
Once the Hilitand PT100 RTD Temperature Sensor Probe is correctly installed and wired, it will begin providing temperature readings to the connected temperature controller or data acquisition system. The sensor operates passively, changing its electrical resistance in proportion to temperature.
- System Power-Up: Power on your temperature controller or data acquisition system.
- Monitoring Readings: Observe the temperature readings displayed on your connected device.
- Controller Configuration: Refer to the instruction manual of your specific temperature controller for details on setting parameters, calibration, alarm limits, and control logic. The PT100 sensor provides a standard resistance output that is widely compatible.
7. Maintenance
- Regular Inspection: Periodically inspect the sensor for any signs of physical damage, corrosion, or wear, especially in harsh environments.
- Connection Integrity: Ensure all electrical connections within the terminal head remain tight and free from moisture or contaminants.
- Probe Cleaning: If the probe tip accumulates buildup from the process media, carefully clean it using appropriate methods that do not scratch or damage the stainless steel. Avoid abrasive materials.
- Storage: If the sensor is removed from service, store it in a clean, dry environment to prevent damage and corrosion.
