RTD temperature probes for process technology (chemical and petrochemical plants, pressure
vessels, etc.) are preferentially used for measuring temperatures in liquids and gases. These
RTD temperature probes consist of a protection fitting per DIN 43763 with various process
connection options, a terminal head and a replaceable measuring insert. The protection fitting
is made of material 1.4571 as standard. Other materials are available for special applications.
All fittings are manufactured in accordance with the pressure vessel regulations and are
subjected to a pressure and leakage test. The measuring insert is normally fitted with a Pt100
temperature sensor as per DIN EN 60751, Class B in 2-wire circuit; versions with two Pt100
measuring circuits are also available as well as 3- and 4-wire circuits. An analog or
programmable transmitter can be integrated for measurement transmission with a 4 to 20 mA
or via the HART ® interface. Versions with flameproof enclosure or intrinsic safety are available
for temperature measurement in areas with an explosion hazard. For documentation purposes,
the device parameters (measurement tolerance, material, etc.) can be certified with a works test
certificate.
Push-in and screw-in RTD temperature probes with connecting cable and ATEX approval can
be provided on request.
