Product overview
PC10 piezoresistive silicon pressure sensor is the core component for the manufacture of pressure sensors and pressure transmitters. As high-performance pressure sensitive component, PC10 can be easily amplified and assembled into the pressure transmitters with standard signal output.
PC10 packages diffused silicon pressure sensitive die to 316L stainless steel housing. External pressure is transmitted to pressure sensitive die through stainless steel diaphragm and internally sealed silicon oil. Pressure sensitive die does not directly contact with measured medium, forming all solid structure of pressure measurement. So the product can be applied to a variety of occasions, including harsh corrosive medium environment.
PC10 uses O-ring for pressure seal, which is easy to install.
The company can also undertake special customization based on the needs of users, such as pressure sensors of all welded structure, wide temperature compensation, high reliability, anti-shock and anti-vibration sensors, especially for national defense weapons and equipment.

Example: PC10-10kG4wI1CPC10 pressure sensor, pressure range 10kPa, gauge pressure, 4 wire, 1.5mA excitation, current compensation.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 to select 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.6 For special requirements on performance parameters and functions of the product, please contact us.
