Description and application

JS 130B thermowell
inside diameter 7.0 mm

JS 130B thermowells are component parts that are usually screwed in or welded in a pipe line. They protect the measuring part of the sensors against the influence of the liquid being measured. Thermowells enable the replacement of the temperature sensors while the technological equipment is in operation.

All of the thermowell types manufactured by SENSIT s.r.o. are made of high-quality stainless steel 1.4301. They are standardly provided with G1/2" thread, but is also possible to deliver them with the G 3/8", M 20 x 1.5, M 27 x 2 threads or even others if necessary.

JS 130B thermowell are designed for temperature sensor with stem and plastic connection head (immersion temperature sensors), temperature sensors MINI series, temperature sensor with stem and metal connection head (immersion temperature sensors), temperature sensor with stem and stainless steel connection head, PTS 580P, PTS580K.

In addition to the standard lenghts listed in catalogues, thermowhells can also be manufactured in non-standard lenghts.

Temperature sensors are locked in the thermowhell with a M4 x 10 screw.

Thermowhells are manufactured for the nominal pressure PN 63.
