Strut & Tube Type Thermostat is comprised of two basic parts - [1] the outer shell made of high expanding metal and [2] the strut assembly made of low expanding metal. A pair of electrical contacts is mounted on the strut assembly and installed in the shell under tension or compression. Shabari Heaters & Control manufactures Strut & Tube Type Thermostat.
Shabari Heaters & Control is the manufacturers of Thermostats, Fire Detectors, heating Elements, Thermocouples, RTD Sensors, PT-100 & Spare Parts for Strip / Blister Pack Machines. The adaptation of the differential expansion principle gives several important control advantages to the Strut & Tube Type Thermostat. Because each end of the strut assembly is mechanically connected to the ends of the shell, a net change in force is produced on the low-expansion strut assembly as the high expanding shell expands or contracts with changing temperature. The temperature at which the contacts “make” or “break” can be regulated. The accuracy is considerably better than that obtainable from other types of Thermostat, such as the snap acting type. Low load switching differentials of less than 0.1 degree C are achieved.
