Precautions:
1. When using contact temperature sensing installation, the product should be close to the installation surface of the controller.
2. Do not crush or deform the plastic or metal shell during installation, so as not to affect the performance
3. Metal shell products with an insulating cover should not be removed or crushed during the installation process to avoid leakage and ensure safe use
Normally closed: The temperature control switch is in the working state (passage), and it will trip (disconnect) when the temperature exceeds the temperature control temperature, and it will not work.
Normally open: It is open circuit (not working) if the temperature is not exceeded, and it starts to work when the temperature is exceeded

Temperature detection method: connect the two leads of the sample to the fixture of the test equipment, pass a current of about 10mA (not more than 100mA), use a light-emitting diode to indicate the on and off of the current, and then put the sample into the special temperature measuring device Inside, (the temperature in the test equipment should be uniform, and the heating rate can be controlled) The thermometer probe should be close to the sample, and the temperature of the testing equipment should be controlled to increase at a rate of 0.5 to 1 ?/min. When the light-emitting diode is on, write down the thermometer reading. The operating temperature of the sample.
Working principle: KSD9700 uses a square bimetal as a temperature sensing body. When the temperature rises to a certain value, the square jumps, the transmission contact moves quickly to disconnect the circuit, and when the temperature drops to a certain value, the bimetal resets , The contact also restores to its original state, achieving the purpose of making and breaking the circuit. Its light volume and compact design maintain the lightness and compactness of the entire device
The sealed shell is resistant to baking and maintains the accuracy of disconnection and reset during the entire life span, ensuring a high degree of reliability.
