• Cold storage facilities

It ensures reliable RTD signal acquisition for automated logic control, process safety, and high-accuracy data logging.

Technical FAQ

Q: Can the ATR8D-00 be used with thermocouples?
A: No. This module is specifically designed for RTD resistance measurements. Thermocouples require specialized blocks with cold-junction compensation, such as the ATS series.

Q: What is the advantage of pressure clamps over traditional screw terminals?
A: Pressure clamps maintain constant wire tension, compensating for thermal expansion and contraction. This ensures reliable connections in high-vibration environments, unlike screws that may loosen over time.
