Talking about salt spray test chambers and its several temperature control devices

The key effect of the salt spray chamber temperature controller is to cause physical deformation in the power switch according to the temperature change of the office environment, and then produce some du te effects, and will cause a series of automatic hydraulic control systems that are on or off the posture, so it is also called a temperature control switch, temperature protection device, temperature controller
。 In the sales market of the environmental trial manufacturing industry, there are five kinds of sudden temperature controllers, liquid rising temperature controllers, working pressure temperature controllers, electronic temperature controllers and their digital explicit temperature controllers, which have different advantages and integration characteristics
。 、1.
Sudden jump temperature controller salt spray test chamber bimetallic sheet sudden jump temperature controller is this kind of bimetal sheet after constant temperature as a more sensitive reflection of heat, and when the temperature of the main part of the commodity rises the heat required to be transmitted to the bimetallic disc, exceeding the posture temperature setting when the rapid posture, according to the tissue efficacy is the contact point is broken or closed; When the temperature is reduced to the calibration temperature setting, the bimetal quickly responds to the original appearance, closing or breaking the contact point, beyond the purpose of connecting or breaking the power circuit, and then controlling the loop
.
2.
Liquid rising temperature controller is when the temperature of the other half of the manipulation changes greatly, so that the chemical substances (usually liquid) in the temperature sensor part of the temperature controller cause a relative thermal expansion and contraction of the physical phenomenon (volume transition), and the membrane box connected to the temperature sensor part causes swelling or convergence, this temperature controller is suitable for home appliances, electric heating equipment, refrigeration manufacturing industry and other temperature control places
。 3.
Working pressure type temperature controller The temperature controller according to the closed type of temperature sensor steam parameters of the bulb and capillary, the transformation of the controlled temperature into the indoor space working pressure or capacity change, when the temperature preset value, according to the elastic element and rapid instantaneous organization, fully automatic shutdown of the circuit breaker, in order to exceed the automatic control system temperature of the purpose, suitable for cooling equipment and heaters and other places
。 4.
Electronic temperature controller is the choice of resistor temperature sensor way to clearly measure, usually use white gold wire, copper wire, filament and its thermistor as temperature measurement resistor, this resistor has its advantages, usually central air conditioning most of the application thermistor type, it has the advantages
of stability, light weight.
5.
Number explicit temperature controller Salt spray test chamber number explicit temperature controller is this kind of temperature measurement control board, which can carry out large numerical quantitative analysis and manipulation
of temperature.
Its principle is to conceive the NTC thermistor controller or thermal resistance design into the relative power circuit, NTC thermistor controller or thermal resistance changes with the temperature change, it will cause the relative current and voltage to change, and then according to the microprocessor for the changed current and voltage to carry out inspection, quantitative analysis to display the information out, and do relative manipulation, it has the characteristics
of improved degree, good sensitivity, visualization, and convenient practical operation.
