What is ksd301 thermostat? Temperature and humidity transmitter controller is used to measure the temperature and humidity of the equipment. It calculates and analyzes the data collected by the sensor to the computer. Temperature and humidity transmitter controller is composed of microprocessor, LCD screen, key switch and so on. If the total high temperature is connected to the cooling system, the system can cool the system below the set value for continuous heating.

According to the production principle of temperature controller, temperature controller can be divided into the following five categories:

Relay, a., relay, various types of general KSD, common such as KSD301 KSD302, such as the thermostat is bimetallic thermostat a new generation of products, the thermostat generally used together with electric heater, when the temperature reached set value, on or off circuit, reached the | purpose of temperature control.

Two, liquid temperature controller: when the temperature of the controlled target is changed, the physical phenomenon (volume change) of the substance (usually liquid) in the temperature controller temperature sensing part of the corresponding thermal expansion and contraction (volume change), and the membrane box connected with the temperature sensing part of the expansion or contraction. The lever principle drives the on-off action of the switch to achieve the purpose of automatic temperature regulation. The liquid expansion temperature controller has the features of accurate temperature control, stable and reliable, small temperature difference between opening and stopping, large temperature control and conditioning range, large overload current and so on.

Three, pressure temperature controller, pressure temperature controller through the temperature envelope and capillary filled temperature medium, the controlled temperature change into space pressure or volume change, reach the temperature set value, through the elastic element and quick instantaneous mechanism, automatically connected or disconnected contact, in order to achieve the purpose of automatic control of temperature. It is composed of three parts: temperature sensing part, temperature setting body part, micro switch or automatic damper for opening and closing

Four, electronic temperature controller, electronic ksd301 temperature controller (resistance type) is the selection of resistance temperature sensing method to measure, generally choose gold wire, copper wire, tungsten wire and thermistor as temperature resistance, these resistors have their own characteristics. General household air conditioning mostly uses thermistor type. Electronic ksd301 temperature controller has the advantages of stable and small size, and it is used more and more widely in many fields.

Five, digital temperature controller, digital electronic ksd301 temperature controller is a kind of accurate temperature detection controller, can carry out digital quantitative control of temperature. Temperature controller generally selects NTC thermal sensor or thermocouple as the temperature detection element, its principle is: the NTC thermal sensor or thermocouple is planned into the corresponding circuit, NTC thermal sensor or thermocouple with temperature changes, will produce the corresponding voltage and current changes, Then through the micro controller to change the voltage and current detection, quantization display, and do the corresponding control. Digital ksd301 temperature controller has the characteristics of high accuracy, good sensitivity, intuitive, easy to operate and so on.
