By understanding the application field and working principle of the P51-15-G-Z-I12-20MA-000-000 pressure sensors, engineers and technicians can take advantage of this new and powerful technology.

Application Field

The P51 family of pressure sensors and transducers offer a host of applications for a variety of industries. The sensors are used in industrial processes such as fluid and air pressure monitoring, hydraulic valve control, boiler level measurement, etc. They are also used in medical applications such as respiratory monitoring, blood pressure monitoring, and infusion therapy control. The sensors are reliable and able to withstand a wide operating temperature range (from -10 to +80 °C). They also come with an IP65 rating, making them suitable for a variety of harsh and hazardous environments. In addition, the P51 family of sensors is RoHS compliant, making them an attractive solution for industries that need to adhere to environmental regulations.

Working Principle

The P51 family of pressure sensors and transducers is based on a piezoresistive silicon sensing element. This technology is able to measure pressure over a range of 0-20 mbar to 0-20 bar (gauged pressure). This range makes the pressure sensor ideal for applications that require both small and large pressure measurements. The piezoresistive element consists of a layer of doped silicon which is protected from external elements by a protective film. When a pressure is applied, the film is deformed and a strain is introduced in the material. This results in a change in the electrical resistance of the material, which is measured to determine the pressure.

The sensors use a 4-wire Wheatstone bridge output circuit, which is connected to a signal conditioning IC. This provides an amplified output signal of 0.5 to 4.5V. The signal can be tailored to suit specific applications through the presence of programmable features such as offset, full scale, hysteresis, etc. The P51 family of sensors also includes features such as temperature compensation, which improves accuracy and repeatability of the sensors. The whole system is powered by a 3.0V-3.3V supply voltage.

Conclusion

The P51 family of pressure sensors and transducers offer reliable and accurate pressure measurements for a variety of industrial and medical applications. The piezoresistive silicon sensor technology and the 4-wire Wheatstone bridge output circuit allow the sensors to measure pressure over a range of 0-20 mbar to 0-20 bar (gauged pressure). The signal can be tailored to suit specific applications through the presence of programmable features such as offset, full scale, and hysteresis, and the sensors can also feature temperature compensation technology for improved accuracy and repeatability. The P51 family of sensors is RoHS compliant and rated IP65, making them a reliable and attractive solution for a variety of industries.
