Plug-in thermocouples are used to measure or regulate temperatures in ranges up to 400°C, for example, in polymer processing machines, injection moulding machines, cylinder heads and oil tubes of motors, bearings, pipelines and containers, generators and transformers. They are usually plugged into a hole in the machine and are easy to replace. Plug-in thermocouples have a spring-loaded mounting and a bayonet cap. The receiving joint (screw-in bayonet nipple or sheath) is available as an accessory.
EPHY-MESS plug-in thermocouples, which have short response times, absorb heat via the highly heat conductive base of the protective pipe (stainless steel). The shape of the bottom (flat, spherical, drill angle 120°) can be adapted to the geometry of the hole for better heat transfer. The thermometers are also manufactured with a compression spring and a bayonet cap, whereby the sensor is firmly pressed against the bottom of the screw-in or the drilling hole and a better thermal coupling is achievable depending on the application.
The standard thermocouples are of type J (Fe-CuNi) and type K (NiCr-Ni). Custom made units with other thermoelectric wires (types L, S and R) are possible. Sensors can be assembled with either one sensor or two thermocouples, which use strengthened isolated thermal wire, or a directly attached compensation wire on the cable outlet side.
