Product Description

 

Product Description

Product Overview
PC40  piezoresistive silicon pressure sensor is the core
component for the manufacture of pressure sensors and
pressure transmitters. As high-performance pressure sensitive
component, PC40 can be easily amplified and assembled into
the pressure transmitters with standard signal output.
PC40 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.
PC40 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.

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, PC40 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 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.
