Temperature instrument selection, for example (1) temperature control. Temperature control range of 300 ℃ ~ 1000 ℃, 380V three-phase resistance wire heating, power of 50kW, requirements volatility around 5 ℃. K even suggested the use of two digital display measurement and control instruments, the range is 0 ℃ ~ 1200 ℃, resolution 1 ℃, relay hysteresis 1 ℃ ~ 2 ℃. Range of motion control contact is ± (1 ~ 2) ℃, plus the furnace temperature measurement lag, basically furnace temperature fluctuation can be controlled within the desired range. (2) oven temperature. Requirements for temperature measuring range of 100 ℃ ~ 400 ℃, 220 V single-phase resistance wire heating supply temperature controller, power of 3kW, temperature stability required to achieve ± 0.5 ℃. By temperature stability index temperature table, use digital control thermostat can not meet the requirements. Optional TMC300 Temperature Monitor (Shenyang Academy of Instrumentation Science production) or other similar products. Instrument molybdenum resistance as the temperature sensing element, and control temperature range -50.0 ℃ ~ 600.0 ℃, resolution 0.1 ℃, the measurement accuracy of 0.2%, continuously adjustable duty cycle control mode. According to the temperature change of the working environment, a physical deformation occurs inside the switch, resulting in some of the special effects, produce a series of automatic control element is turned on or off operation, called temperature control switch, also called a temperature controller or temperature protection, referred to the thermostat. Or through the temperature reached the temperature protection thermostat temperature controller import table, temperature controller sends the switching commands to control the operation of the equipment in order to achieve the desired temperature and energy savings. In air conditioning, the temperature controller is a temperature of air-conditioned room controlled electrical switching apparatus. Temperature controller controlled air conditioning in the room temperature range is generally 18 ℃ ~ 28 ℃. Window air-conditioning temperature controller is based on common principles of pressure to push through and break contacts. Its structure consists of a bellows, thermal package (test tube), eccentric, micro-switches and other components in a sealed sensor system and a signal power transfer system.
