    0 °C). The nominal values are normally 100 Ω (Pt100), 500 Ω (Pt500), and 1000 Ω (Pt1000). The RTD temperature probes in the type series 902454/10 and 902454/11 for direct mounting, and 902464/10 for installation in thermowells have national type approval for cold meters. When it comes to use on combined cold/heat meters, these temperature probes also have an EC type examination in ac- cordance with EC Directive 2014/32/EU (MID) including Appendices I and MI-004.

    Installation 4 Installation If the pair of temperature probes is connected to a computer unit, make sure that the probe's nominal value matches that of the processing computer unit. Furthermore, make sure that the installation location is deep enough to prevent damage to the tip of the probe or thermowell when screwing in.

    4 Installation Installation notes The cold barrier serves the thermal decoupling of the terminal head. This prevents condensation forming in the terminal head. Condensation forms on surfaces with a temperature below the dew point tempera- ture of the surrounding ambient air. In a normal room environment of 20 °C and 50 % relative humidity, the dew point temperature is approx.

  • Page 17: Maintenance

    Maintenance 5 Maintenance In order to maintain measurement stability, a metrological inspection must be carried out when the cali- bration period/the metrological identification marking has elapsed to check that the maximum permissi- ble error (MPE) is observed. At the same time, to maintain leak-tightness, at least every 5 years the seal on the cable entry and the terminal head lid must be replaced.
