China Flush Diaphragm Pressure Sensor with Clamp Film Pressure Transducer PC112K, Find details about China Pressure Sensor, Transducer from Flush Diaphragm Pressure Sensor with Clamp Film Pressure Transducer PC112K
PC112K Flush Diaphragm Pressure Sensor with Clamp
Product overview
PC112K pressure sensor adopts a single time silicon oil filling technology. The perceived pressure is transmitted to the pressure chip through the silicone oil to generate an electrical signal, and the compensation circuit corrects the pressure signal to a linear pressure signal. The clamp face diaphragm is exposed to direct pressure, which can prevent scaling, unsanitary and viscous pressure blockage. It is especially suitable for viscous fluid pressure and liquid level measurement in the medical and food industries. It is widely used in food, pharmaceutical, winemaking and other sanitary industries.
The company can customize products for customers, to make products of special structure and size. We have mature batch production lines, which can ensure production tasks be finished perfectly.
