Pressure Sensors, Transducers

A P51-15-S-UC-I12-4.5V-000-000 pressure sensor is a type of pressure transducer. It measures pressure remotely and then transmits electrical signals of varying magnitude to devices or instruments for measurement, readout, recording, and/or control. Pressure transducers measure pressure in several types of media, such as liquids, gases, and steam, to provide information on variables such as pressure, altitude, and depth.

Application Fields

Pressure sensors, transducers, are used in a wide variety of applications, including: industrial process control, refuse systems, air-conditioning systems, water well pumps, medical instruments, energy exploration, aerospace applications, tank level monitoring, automotive safety systems, and civil engineering. There are also applications for automotive, their ability to measure pressure in spark-ignited engines sparks better combustion and fuel economy while making for a safer driving experience.

In industrial applications, pressure transducer/sensors are commonly used in ventilation, sterilization, and medical products such as incubators. They are also critical components in laboratory instrumentation and motion control systems used in various types of automated manufacturing processes such as injection molding, robotic arm movement, and fluid handling applications.

Finally, pressure transducers/sensors play a major role in safety and security systems in a variety of public and private-sector facilities. These systems sense pressure changes and alert personnel in the event of a pressure spike or other significant change in pressure.

Working Principle

The P51-15-S-UC-I12-4.5V-000-000 pressure sensor functioning is based on the "piezoresistive effect". A silicon integrated chip, or microelectronic MEMS (micro-electromechanical systems) sensor is used to measure the pressure differential. When the pressure applied to the diaphragm varies, the piezoresistive elements on the MIC change resistance values.

The sensor measures the change in resistance of these elements proportional to the pressure differential. This voltage signal is amplified, and then converted into a current signal and sent through a transmitter. This current signal is proportional to the pressure applied to the sensing diaphragm in the sensor.

The current signal is sent to a control device where it is converted back to a voltage and then displayed as pressure. The accuracy of the voltage output is usually determined by the accuracy of the transmitter.

Conclusion

A P51-15-S-UC-I12-4.5V-000-000 pressure sensor is a type of pressure transducer that is used in a wide variety of applications. It functions based on the piezoresistive effect, measuring the change in resistance of piezoresistive elements proportional to the pressure differential. The sensor sends a voltage signal to a transmitter, which is then sent to a control device where it is converted back to a voltage so it can be displayed as pressure.
