The temperature relay T21K1 is designed to control and regulate the temperature of gaseous and liquid media, the control limit is from -20 to +10 degrees. The device has a waterproof design. Т21К1 serves for use in refrigeration units, as well as in other systems for monitoring and regulating the temperature of gaseous and liquid media (air, freons, oils, etc.), non-aggressive to copper and copper alloys, tin-lead, silver solders, steels. T21K1-1-02-2 (-20 ... + 10 ° С) technical data The device switches: - 30 W of direct current with voltage 24, 27, 110 and 175-320 V; - 150 VA alternating current with a voltage of 380 V with a frequency of 50 or 400 Hz at cos y> 0.7; - 300 VA of alternating current with voltage of 127 and 220 V with frequency of 50 or 400 Hz at cos y> 0.7; - the minimum value of the switched current is 0.05 A. The temperature relay T21K1 is manufactured in the following modifications, each of which has its own temperature measurement range: T21K1-1-01-1 -35 ... + 5 ° С T21K1-1-02 -20 ... + 10 ° С Т21К1-1-03 + 5 ... + 35 ° С Т21К1-2-03 + 5 ... + 35 ° С Т21К1-1-04 + 30 ... + 60 ° С Т21К1-2-08 + 55 ... + 100 ° C Devices with a protective cover: T21K1-1-03-1-1, T21K1-1-03-2-1, T21K1-2-03-1-1, T21K1-2-03-2-1 are intended for monitoring, regulation temperature of sea water and brines. Temperature relay T21K1 operating conditions ambient air temperature (25 ± 10) С; relative humidity from 40 to 80%, and at an ambient temperature above 30 ° C, relative humidity is not more than 70%; atmospheric pressure from 0.086 MPa (645 mm Hg) to 0.106 MPa (795 mm Hg). The principle of operation of the device is based on the use of the dependence of the pressure of the thermosystem filler on the temperature of the controlled environment and balancing the force created by the pressure on the sensitive element - the bellows by the elastic deformations of the bellows and the spring. During the operation of the device, the temperature of the environment surrounding the thermal bulb corresponds to a certain pressure of the accumulator inside the thermal system.
