What kind of temperature sensor and humidity sensor are used in constant temperature and humidity chambers?
The information of sensor for constant constant temperature and humidity chambers is the calculation time and the lowest level information of the electronic control unit. It is also a very important sensor in the electronically controlled heating and cooling system. The failure of this sensor will cause the equipment to fail to operate normally or even start. Most of the old-fashioned sensors use magnetic induction crankshaft position sensors. Most of the magnetic induction crankshaft position sensors in domestic cars have problems frequently.
So, what kind of temperature and humidity sensor do we usually use in our constant temperature and humidity chamber? Most temperature sensors use platinum resistors and thermocouples(Yuanyao uses PT100 platinum resistor for temp. sensor of climate chamber). Humidity measurement methods are mainly divided into the following two types: wet and dry bulb thermometer measurement method and solid-state electronic sensor direct measurement method(depend on customer test requirement choose different type humi. sensor, normally use former). Since the measurement accuracy of the former is not high, it will be gradually replaced by solid-state sensors as the test chamber is gradually upgraded.
Once there is a problem with the sensor of the test chamber, the main fault symptoms are:
a. The temperature does not meet the requirements;
