Pressure Sensors, Transducers

A P51-2000-S-H-D-20MA-000-000 is a pressure transducer utilized in a wide range of applications. It is a pressure-to-electrical signal transducer that converts a pressure input to an electrical output signal.

Application Fields

The P51-2000-S-H-D-20MA-000-000 can be used for many different applications. It is widely employed for measuring several process parameters in industrial process control applications, such as in oils and gas production, aerospace and automotive, and HVAC applications. Moreover, the sensing element in this transducer makes it well suited for measuring static and dynamic pressures in the vacuum, pressure and temperature ranges.

In addition, this transducer can be used in multiple environment settings, such as hazardous areas, as well as in harsh environments with temperatures as low as -40°C. It is also suitable for applications that require reliable performance in aggressive media, such as seawater.

Working Principle

The working principle of the P51-2000-S-H-D-20MA-000-000 is based on the piezoresistive effect. This effect states that when pressure is applied to a semiconductor, the electrical resistance of the semiconductor changes. The sensor of the transducer contains a diaphragm, which is connected to a Wheatstone bridge circuit, which in turn is connected to a reference pressure. This bridge is used to convert mechanical movement to an electrical signal.

When pressure is applied on the diaphragm, its resistance changes, resulting in a change in the output voltage of the transducer. This change in voltage is proportional to the amount of pressure being applied. The signal is then amplified and converted to a standard signal, using internal circuits.

Finally, the signal is transmitted to a receiving device to be compared against known thresholds and to be monitored over time. Depending on the application, the transducer may also be designed to be portable or installed in a fixed location in the process or production machinery.

CONCLUSION

The P51-2000-S-H-D-20MA-000-00 is a pressure transducer with a wide array of applications. This pressure transducer consists of a diaphragm and Wheatstone bridge circuit, which converts mechanical motion to electrical signals. This signal is then amplified and transmitted to receivers in order to be monitored and measured over time, and to compare it against certain thresholds. This transducer is also suitable for a wide range of environments, and is highly reliable in aggressive mediums such as seawater.
