RLC thermostat - temperature controller control method classification and working principle

The first output method is relay output, which is output for temperature control through the switching signal of the relay on/off, which is used to directly control the load less than 5A, or directly control the contactor and the intermediate relay, and control the high-power load externally through the contactor. The second ...

1. What is the principle of the sudden jump thermostat? The sudden jump thermostat is a kind of thermostat, which is a series of automatic control elements that are physically deformed inside the switch according to the temperature change of the working environment, resulting in some special effects and on-off action. Sudden jump ...

The temperature controller is an electrical switchgear that controls the temperature of an air-conditioned room. The temperature range in the air-conditioned room controlled by the temperature controller is generally 18°C--28°C. The temperature controller commonly used in window air conditioners uses the principle of pressure to push the contacts on and off. Its structure consists of bellows ...

The reasons why the temperature control table shows HHH are as follows: 1. The thermocouple signal line is reversed, or short. 2. If the temperature control meter is in normal use before, it is recommended to check whether the signal line of the thermocouple is broken. 3. The wire inside the thermocouple is broken. 4 ...

1. Lower limit deviation alarm setting: Press the SET key to select and display "SLP", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter. This parameter indicates the difference between the alarm point and the master setpoint. 2. The upper limit deviation alarm is set ...

The correct selection of the level gauge can ensure the better use of the level gauge. What kind of level gauge should be selected according to the physical and chemical properties of the fluid medium to be measured? What is the diameter of the level gauge, the flow range, the lining material, the electrode material, and the output current? can adapt to the ...

　　Analog-to-digital converters The analog-to-digital converter comprises a first transmission circuit, which receives an input voltage and an output clock signal, which is phase-shifted, depending on the input voltage, and a second transmission circuit receives a reference voltage and an input clock signal, and outputs a reference clock signal, which ...

1. Sudden jump thermostat The type of various sudden thermostats is collectively called KSD, such as KSD301, KSD302, etc., the thermostat is a new type of bimetal thermostat, mainly as a variety of electric heating products with overheat protection, generally connected with the thermal fuse in series, sudden temperature ...

1. Mechanical The sensitive gas diaphragm box or thermal bimetal sheet is used as the temperature sensing element to form the temperature control switch of the mechanical contact. This kind of thermostat is more in the European and American markets, and only a few domestic manufacturers promote such products.
