Temperature controller, as the name suggests, is a kind of magical machine that controls the temperature according to the changes in external temperature. Generally, changes in the temperature of the outside world will be perceived by its internal structure.Of course, there is also a temperature controller that can change the external temperature by changing the internal structure. Among many electrical machines, the use of temperature controller is actually used.
Temperature controller manufacturer
The establishment time of the manufacturer of Shanhua Refrigeration temperature controller in Lubu Town, Yuyao City was on May 14, 2001. Its main device, the cold storage micro computer temperature controller, air -conditioning temperature sensor, and so on.This manufacturers equipment is very complete, and it also has a scientific quality management system. The integrity of the manufacturer and the quality of the product have been recognized by the industry.The establishment time of the manufacturer of the famous temperature controller manufacturer of Zhongshan City is March 16, 2009, and the registered capital is RMB 500,000.No. 7 first.It mainly operates production products including temperature controllers, self -control equipment, low -voltage electrical appliances, instruments, pressure numbers, temperature and humidity meters, resistor tester, voltage meter current, close to switches, transmitters, etc.This manufacturers products are relatively complete, and the quality of the product is relatively stable and reliable. The purpose of this manufacturer is "production of famous products, production products" continuously developing and innovating products with more reliable quality.
Temperature controller working principle
1. (Frequency air conditioning) to reach the set value, the outdoor machine stops working, the indoor machine is maintained to ensure the air circulation. When the indoor temperature gradually increases, when the setting value is 2-3 ° C, the outdoor machine is restarted to the refrigeration. The indoor indoor isThe temperature will begin to decline again, and repeat this process.The indoor temperature can be maintained in the set temperature value of about 1 ° C.2. (Inverter air conditioning) is close to the set value. The frequency of output of the inverter board of the outdoor unit starts to decrease, the speed of the compressor decreases, and the refrigeration capacity is decreased accordingly. The indoor temperature is kept under the same value as the set value.With the change of indoor thermal source, the indoor temperature sensor detects the changes in temperature in real time, and the control signal output of the main control board outputs the inverter follows the changes to adjust the working frequency of the compressor, thereby changing the instantaneous refrigeration volume and ensuring that the indoor temperature is stable.
Temperature controller price
Due to the different requirements for temperature controllers in different places, the price of temperature controller is also very large.The simple temperature controller used in ordinary families is generally about 30 yuan, such as Chen Yuan Computer Smart Temperature controller; a slightly better number display micro -computer intelligent temperature controller, generally 60 RMBA better thing is the number display+humidification and dehumidification temperature controller, generally 130 RMB, such as Beilong high -precision temperature and humidity control instrument;These general users large factories or power stations and other places.
Temperature controller wiring method
There are many types of temperature controllers. There are many temperature controllers produced by different models produced by different businesses. Their wiring methods are a little different. You must not copy a mode to wiring them.The probe of the thermostat is actually the resistance of the resistance. There are generally three types of wiring methods, that is, the thermocouple wiring, the output wiring (control wiring), the temperature compensation resistance cable, the different temperature wiring, the use of the wiring method may be possible.It is one of them. The specific instructions are generally described in the manual. Everyone can find it in the manual carefully.
Temperature controller instructions
Mechanical and electronic: Mechanical uses two layers of thermal expansion coefficients and different metals. When the temperature changes, his curvature will change.The circuit makes the cooling (or heating) equipment work.The electronic format changes the temperature signal into an electrical signal through the temperature sensing device such as thermocouple and platinum resistance, and controls the heating (or refrigeration) equipment (or stop) through the single -chip microcomputer and PLC and other circuits.There is also a mercury thermometer type, and there will be contact and mercury to connect with the temperature.
