The screw-in RTD temperature probe with connection head is specially designed for use in various industries such as air conditioning and refrigeration technology and heating, furnace and apparatus engineering. It offers precise temperature measurement in both liquid and gaseous media, with a temperature range of -50 to +400 °C.
The installation design of this thermometer ensures reliable tightness, even under extreme conditions of negative and positive pressure.
The measuring insert is fitted as standard with a Pt100 temperature sensor in accordance with the DIN EN 60751:2009 / IEC 60751:2008 standards. This sensor has a temperature coefficient α of 3.850 × 10-3 °C-1 and is installed in a two-wire circuit. Versions with Pt500 or Pt1000 are also available as an option. For more precise measurement results, the connection can be made either in a three-wire or four-wire circuit, and it is also possible to integrate a transmitter into the connection head.
Depending on the measurement requirements, a single or dual resistance thermometer can also be selected.
