China Flush Diaphragm Piezoresistive Silicon Sanitary Pressure Transducer PC12K

Product overview
PC12K clamp type pressure sensor adopts one-time silicon oil filling technology. The pressure felt by the diaphragm is transmitted to the pressure chip through the silicon oil, and the compensation circuit corrects the pressure signal into a linear electric signal. The clamp face diaphragm is exposed to direct pressure, which can prevent scaling, unhygienic and sticky pressure blockage and other problems. It is widely used in food, pharmaceutical, wine-making and other sanitary industries as well as occasions where the measuring medium may be fouled.
Customization is available for special structure and size of the product. The company has a mature batch production line that can complete production tasks in time with quality.

How to order

Example: PC12K-35kGI1K1H1T0
Refer to product model PC12K, with pressure range 35kPa, gauge pressure, 1.5mA constant current excitation, 1.5" clamp, no cooling fan, and rear thread M25x1.
Ordering tips:
1 Pressure range can be selected higher or lower than actual conditions but should be within ±30%FS.
2 Pressure reference consists of gauge pressure, absolute pressure and sealed gauge pressure.Gauge pressure is based on the current atmospheric pressure. Generally, it refers to the measurement of pressure which is greater than the current atmospheric pressure. Negative pressure is a special case of gauge pressure. It refers that there is such working condition that the pressure of work site is lower than the current atmospheric pressure.Absolute pressure is based on vacuum.As for sealed gauge pressure, PC10 uses absolute pressure die for gauge pressure product based on the atmospheric pressure of production site. For pressure range above 6MPa, gauge pressure cannot be selected, but only sealed gauge pressure.3 Confirm the maximum overload of the applied system, which should be less than the overload protection limit of the sensor, otherwise it will affect the product life or even damage the product.
4 The commonly used compensation of the product is 1.5mA constant current compensation. Suggest selecting the option with priority.
5 The material and process for manufacturing negative pressure sensors are different from those of positive pressure sensors. So gauge pressure sensors cannot be used as substitute of negative pressure sensors.
