Product overview
PC13 piezoresistive silicon pressure sensor is the core
component for the manufacture of pressure sensors and pressure
transmitters.As high-performance pressure sensitive component,
PC13 can be easily amplified and assembled into the pressure
transmitters with standard signal output.
PC13 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.
PC13 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.

How to order
PC13 I - 10M S 4w I1 C
Example: PC13I -10MS4wI1C
PC13I pressure sensor, pressure range 10MPa, sealed 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.
⑴Gauge 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.
⑵Absolute pressure is based on vacuum.
⑶As 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 1.5mAconstant 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.
