Thermal resistance for heat meters is particularly suitable for temperature measurement in closed piping systems. Install it in a close-contact protective sleeve. When the warranty period is reached, you can replace it without venting the system. The sensor usually uses an EN 60 751, Class B, two-wire PT100 thermal resistance. PT500 and PT1000 are also available. Products with junction box can choose two-wire, three-wire and four-wire circuit connection. In the temperature range of 20-150°C, this kind of thermal resistance can be tested, paired and certified in the UST thermal test laboratory KF2.
The thermal resistance measurement and certification department complies with Article 28 of the German Federal Law of August 1, 2001.
