TR 151
diametr 6 mm, -20 °C to 105 °C

Description and application

TR 151
diametr 6 mm, -20 °C to 105 °C

Temperature sensors TR 151 in the plastic case are intended for temperature measurements of gaseous, eventually liquid materials. For long-lasting temperature measurements (especially at the temperatures over 90 °c) there is better to use the sensor with thermowell-combination. The sensors have always plastic polyamid case in which the temperature sensing element is located.

The case diameter of  TR 151 is 6 mm. All types of resistence sensing elements used by company SENSIT s.r.o. can be used. The wiring of the sensors is always 2-wire.

Material of the case has medium resistivity to atmospheric aging, it resists oils, fuels, hydraulic liquids, alifatic and aromatic hydrocarbons, esters, ketons and slight alcalis. Material is not resistant to acids, strong alcalis and chlorinated hydrocarbons.
