Temperature Measurement


Resistance thermometer for harsh conditions

September 2018 Temperature Measurement

Due to their extreme insensitivity to vibration, impact and shock load, Kobold’s TNK resistance thermometers are particularly suitable for monitoring the temperature of diesel engines. The extremely robust measuring devices are best suited for use in shipbuilding and mechanical engineering and meet all the technical requirements set by leading shipbuilders like Germinsche Lloyd and Deutsche Bahn. Available solutions for the process connection include threaded nipples or screw connections.

Different sensor types, such as Pt 100, Pt 1000 or Ni 100, Classes A and B, and also different sensor lengths and materials make it possible to design the measuring device to best suit the application in question. The measuring resistances can be replaced without having to remove the fitting. These instruments, available as 2, 3 or 4-lead versions, cover measuring ranges from -80 to 150°C. Maximum operating pressures are 16 or 50 bar, depending on the type of the connection.

The saltwater-resistant, protection type IP65 aluminium connection casing provides secure protection. Besides the standard industry solutions for engines, cable connections can be chosen that conform to DIN 89280 or VG 88812 for use in ships or for military purposes. Materials used are brass, saltwater resistant bronze or stainless steel.

TNK finds application in shipbuilding, diesel engines, engine building, mechanical engineering and power unit construction.
