Capillary thermometer TCS 48

TThe TCS 48 is a capillary pressure thermometer intended for temperature measurements in applications where the measurement readout is remote from the sensing location. The thermometer comprises a capillary system and a dial head. The dial head comprises a housing and a plastic cover, which protects the dial face and pointer, and a flexible pickup. The thermometer sensing element is an Archimedes spiral tube. The internal pressure from the thermal expansion of the liquid medium in the sensing element causes the spiral to unwind. The unwinding motion is rotary and proportional to the pressure, which the flexible pickup translates to the pointer to provide the reading on the scale. The sensing element and the spiral are connected by a capillary tube.
