The plug-in resistance thermometer enables temperature measurement in gaseous and liquid media due to the temperature dependence of the electrical resistance of its built-in platinum sensor. The tried-and-tested plug-in shape ensures reliable tightness under negative and positive pressure. The resistance thermometer is therefore ideal for use in air conditioning and refrigeration technology as well as in heating, furnace and apparatus construction. The resistance thermometer according to DIN EN 60751 (class B) is designed as a 1 x Pt100 in a two-wire circuit and is designed for temperatures from -50 to +200 °C. The offset protective tube made of stainless steel 1.4571, which is designed for air measurement, protects the measuring insert against chemical influences and mechanical damage. The dimensions are 6 x 290 mm, with the tip offset to 3.3 mm. The connection head in form J is made of die-cast aluminum, has a cable gland M16 x 1.5 and can withstand temperatures from -40 to +100 °C.
