Requirements for installation sites for high and low temperature test chambers In order to facilitate heat dissipation and maintenance of the cabinet, the installation of high and low temperature test chambers must meet the following conditions:
1. Distance between adjacent walls or objects is 300mm
2. In order to stably play the function and performance of the test box, the place where the annual temperature is 15~35°C and the relative humidity is more than 85% should be selected.
3. The ambient temperature of the installation site should not be changed drastically.
4. It should be installed on the horizontal surface (the level is confirmed on the ground when installing the level).
5, should be installed in places without direct sunlight.
6, should be installed in a well-ventilated place.
7. It should be installed away from combustibles, explosives and high temperature heat sources.
8, should be installed in places with less dust.
9. Install as close as possible to the power supply.
According to the temperature change of the working environment, the thermostat will have some physical deformations within the switch, resulting in some special effect. The thermostat will cause a series of automatic control element of turning off and turning on, which is also called temperature control switch, temperature controller, temperature protector, referred to the thermostat. Through thermal protector, the temperature protector will send the temperature to the thermostat and the thermostat will send the commands to control the operation of the device in order to achieve the desired temperature and the energy saving effect. Now the thermostat are widely used in thermostat application appliances, motors, cooling, heating and many other products.
The working principle of the thermostat is
automatically sampling, real-time monitoring through the temperature sensor.
The control circuit starts when the ambient temperature is higher than the
control set point. If the temperature still rise, when the temperature rose to
over-limit alarm set point, the thermostat start limit alarm function. When
temperature control can not be effectively controlled in order to prevent
destruction of the device also can be stopped by the trip device features
continue to run.
According to the function of the working,the thermostat have different types:intelligent thermostat,remote controlled thermostat,programmable thermostat,wireless room thermostat.
