PT100 temperature sensor has become the necessary accessories in the life

Microwave oven in our daily life gradually become each family essential kitchen utensils and appliances, and how to determine the microwave food hot enough and won't burn out?

it's need to use PT100 temperature sensor. And the requirement is high performance, stable structure, magnetic interference PT100 temperature sensor.

microwave PT100 temperature sensor structure, including: sensor probe and sensor shell and sensor hole, shell under the cover of the internal set up multiple columns used to support the sensor probe, part of the support column set the bulge at the top of the dowel pin, positioning pin asymmetric distribution, and the sensor probe on the fixed plate number, location and positioning pin corresponding to the positioning hole, when the sensor probe into the sensor shell, positioning pins and locating holes corresponding to cooperate with each other; Under the shell cover at the bottom of the internal space of the prominent positioning plate Settings; Shell cover set pressure column. Sensor probe requires accurate fixed position, the position of the probe and the shell cover at the bottom of the probe hole accurately correspond to each other, and avoid deviation, also can simplify the production and installation process, further to save cost and improve production efficiency.

with the rapid development of science and technology progress of optical fiber temperature sensor, now in the microwave oven has been extensive use of optical fiber temperature sensor, because the optical fiber temperature sensor in the microwave environment is applicable. The temperature sensing system has the advantage that can eliminate the optical crosstalk between adjacent sensing head, reduce the measuring error, so as to achieve high resolution and accuracy. Insufficient place is cost is higher. This greatly limits its application in microwave oven. So now, usually only more upscale microwave optical fiber temperature sensor is used.
