Category: temperature switch

产品描述标题.jpg

      This temperature measurement and control product which integrates temperature measurement, display, 

      output and control.The product is a full electronic structure. The front end adopts a piezoresistive temperature 

      sensor or ceramic piezoresistive sensor with isolation film. The output signal is amplified by a high-precision, 

      low-temperature drift amplifier and fed into a high-precision A / D converter. It is converted into digital signal 

      which can be processed by microprocessor. The signal processed by operation controls two switches to 

      measure and control the temperature of the control system.
