Performance Parameters:
- High measurement accuracy repeatability
- Low power dissipation to prevent self-heating
- Durable construction for long service life
Material and Structural Characteristics:
- Flame-retardant housing material
- Tin-plated copper terminals for low contact resistance
- Molded strain reliefs for incoming cables
Working Principle:
The assembly connects the RTD sensor to the input module’s bridge circuit. By providing a stable connection path, it ensures that the resistance variations caused by temperature changes are accurately transmitted to the measurement electronics without interference from external noise or connection resistance.
Installation Requirements:
- Verify the sensor type and wiring configuration before installation
- Use torque drivers to ensure consistent terminal pressure
- Label all sensor connections clearly
Usage Notes:
- Keep terminals clean and free of debris
- Perform calibration checks against a reference sensor periodically
- Avoid mechanical stress on the terminal assembly during wiring
