The KOBOLD resistance thermometers comprise a rugged installation
fi tting made of stainless steel with thread, fl ange or
weld-on connection, a connection head out of aluminium casting
and a removable measuring element. The measuring insert
can be replaced without emptying the installation, since the
customised thermowell remains in the installation and seals the
process. The instruments are supplied with the ignition protection
Exd as a standard and therefore can be installed in relevant
A Pt100 temperature sensor according to IEC 751, category A
or B is fi tted in the measuring insert as standard. Depending on
customer request the temperature sensor can be carried out as
2-, 3- or 4-wire circuit.
Alternatively these sensors can be designed as single or double
resistance thermometers. Exceptional the 4-wire version, which
can only be build with one Pt100 due to lack of space.
As an option the resistance thermometers can be supplied with
a head transmitter. Transmitter with a standard 4-20 mA signal,
with HART® protocol or with PROFIBUS®/Fieldbus are there to
Beside the available resistance thermometers according to DINstandard,
there are customised versions relating to the immersion
length, the connection head, the materials, the process
connection or the tolerance classes deliverable on request.
