How to test KSD thermostats?
KSD thermostat is a bimetallic disc instantaneous temperature controller with fixed temperature. It is connected to the grounding metal parts of the equipment through the metal cover of the thermostat. Wounds, cracks, deformations, burrs, stains and other defects of value.
The KSD thermostat is an automatic reset type, and the temperature characteristics are as follows:
1. Disconnection temperature OFF: 125±5℃.
2. Reset temperature ON: automatic reset.
KSD thermostat test method:
1. Clamp the thermostat in the test area, wait for the temperature in the temperature measurement area to balance, and then start the test.
2. Air is used as the heating medium in the test furnace, and a thermometer or temperature sensor is placed in the temperature measurement area.
3. Start from 2K before the temperature enters the operating temperature tolerance range, and conduct heating or cooling at a temperature change rate of less than 1K/min.
During this period, stirring must be performed to make the temperature distribution fully uniform.The uniformity of temperature distribution in the temperature measurement area is within ±0.4K .
