Product Description
PC50 Piezoresistive Silicon Pressure Sensor is the core component for producing pressure sensors and pressure transmitters; as a kind of pressure sensitive elements with high performance, it can be conveniently processed through amplifying, and assembled into the transmitter with the standard signal output.
PC50 sensor packages piezoresistive silicon sensitive pressure die into 316L stainless steel housing, the external pressure is transmitted to the sensitive die through the stainless steel diaphragm and internally sealed silicon oil; the sensitive die does not directly contact with the measured medium, so as to form all solid structure of pressure measurement, so this product can be applied to a variety of occasions, including harsh corrosive medium environment.
PC50 sensor adopts O-ring for pressure sealing, easy to install. Our company can also undertake the special customization according to the requirements of the customers, for example, all-welded structure, wide temperature compensation, highly reliable, anti-strong shock and anti-vibration pressure sensors, especially for supporting the national defense weaponry.

Note:
- Calculate according to BFSL least square method.
- Under the excitation of 1.5mA, for different pressure ranges, the outputs are different; the outputs for smaller pressure ranges are smaller, and the outputs for large pressure ranges are larger; if the customers need detailed range information, please ask for the information from our company before placing the order.
- Within the compensation temperature scope, for 0ºC~60ºC and -10ºC~70ºC, the midpoint reference can be 30ºC.
- After passing high and low temperature, return to the reference temperature.

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, PC50 uses absolute pressure die for gauge pressure product based on the atmospheric pressure of production site. For pressure range above 4MPa, 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 this option with priority.
5 The material and process for manufacturing negative pressure sensors are not all the same with those of positive pressure sensors. So gauge pressure sensors cannot be used as substitute of negative pressure sensors.
