Pressure Sensors, Transducers

The P51-1000-S-P-MD-5V-000-000 is a type of pressure sensor which results in a tangible output voltage when pressure is applied. It is designed to measure the pressure of gases or liquids in a variety of applications; ideal for high bulk-modulus gas environments and pressurized cavities. It features a linear operating range from 0-1000 mbar with exceptional repeatability and accuracy. Low power draw and a wide operating temperature range makes this pressure transducer a practical solution in a variety of industrial, medical, and automotive projects.

What is a Pressure Sensor?

A pressure sensor is a device that detects and converts changes in pressure into a measurable voltage or current. A pressure sensor measures pressure, typically within a given medium such as liquid, gas, or air. Pressure range and accuracy are determined by the design and model of the sensor. Pressure sensors typically come in three distinct categories: absolute pressure sensors, differential pressure sensors, and submersible pressure sensors.

Absolute Pressure Sensors

Absolute pressure sensors measure the pressure difference between two points and transduce this pressure into an electrical signal. These pressure sensors rely on a sealed port to measure the atmospheric pressure along with a reference pressure source. The absolute pressure range of absolute pressure sensors is typically from 0-1000 mbar, and accuracy improvements can be attained with additional temperature compensation.

Differential Pressure Sensors

Differential pressure sensors measure the pressure differential between two points and transduce it into an electrical signal. These sensors operate on the same principle as absolute pressure sensors, but they are less sensitive to changes in temperature. These sensors are commonly used in applications where pressure differentials need to be monitored, such as in the calibration of water and air tightness systems. Differential pressure sensors have a pressure range of typically 0-1000 mbar.

Submersible Pressure Sensors

Submersible pressure sensors are mostly used for hostile or wet environments that require the pressure sensor to be fully immersed in the liquid or gas. These sensors are designed to withstand high pressure and are usually hermetically sealed. Submersible sensors are generally used in applications where water or oil level needs to be monitored and controlled. They are also used in medical equipment, such as in heart rate monitors.

P51-1000-S-P-MD-5V-000-000 Application Field and Working Principle

The P51-1000-S-P-MD-5V-000-000 is a absolute pressure sensor that is designed for use in high-modulus, pressurized gas environments. It is based on a transduction principle whereby the pressure applied directly affects the output voltage of the device. Its linear operating range is from 0-1000 mbar and its accuracy and repeatability are further enhanced by temperature compensation.

The P51-1000-S-P-MD-5V-000-000 is suitable for a variety of applications where it can accurately measure the pressure of gases or liquids, including industrial, medical, and automotive-related projects. It is particularly well-suited for applications where long-term stability and accuracy over a wide operating temperature range is required, such as in corrosion-resistant assemblies and liquid-filled cavities.

Conclusion

The P51-1000-S-P-MD-5V-000-000 pressure sensor is designed for use in hostile environments that require a linear operating range of 0-1000 mbar with exceptional accuracy and repeatability over a wide temperature range. It is an ideal solution for industrial, medical, and automotive applications, allowing for accurate pressure measurement of gases and liquids in a variety of applications.
