Pressure Sensors, Transducers

P51-75-S-D-MD-4.5V-000-000 is a type of pressure sensor 16x2 LCD module. Smart pressure sensors, transducers, and gauges are all comprised of an sensor element, a signal conditioner, and an output system. The sensor element measures a physical variable, such as a temperature, pressure, or force, and produces a directly proportional electrical signal. The signal is typically of low level, often less than 5V, and a signal conditioner amplifies the signal into a standardized form for use by the output system. The output system provides a user indication for the desired variable.

Application Field

The P51-75-S-D-MD-4.5V-000-000 series of pressure sensors can measure and display positive and negative pressure differentials from -15 to +15 inches of water and -75 to +75 millibars. Smart pressure sensors, transducers, and gauges are now widely used in industrial, medical, automotive, military, and consumer applications. Examples of applications include, level sensing, altitude measurements, fluid flow measurements, airspeed measurements, exhaust back pressure monitoring, and safety systems.

Sensor Working Principle

The P51-75-S-D-MD-4.5V-000-000 operates using the piezoresistive sensing principle. This sensing technology uses an internal strain gauge which produces a voltage in response to the physical forces experienced. The voltage is amplified and accurately scaled to display the pressure reading.

The transducer housing is typically made from stainless steel or another non-corroding material, which helps to protect the internal components from the environment. This is important because the gauge must maintain accuracy over its specified operating temperature, ambient pressure, and relative humidity ratings.

Other Features

One of the main advantages of the P51-75-S-D-MD-4.5V-000-000 series is that they incorporate a differential pressure sensing feature which allows for measurements of both positive and negative pressure differences. Additionally, this model is equipped with advanced temperature compensation and hysteresis features for adding additional levels of accuracy to the pressure readings.

The 16x2 LCD display of the P51-75-S-D-MD-4.5V-000-000 series is also advantageous as it provides a direct reading of the pressure measurement with no need for a separate display. This also means no external power is required to operate the display.

Applications and Benefits

The P51-75-S-D-MD-4.5V-000-000 offers a range of industrial and commercial benefits that makes it a popular choice for a variety of applications. Its ability to measure both positive and negative pressure differentials makes it suitable for monitoring both fuel and exhaust systems. It is also light weight and compact enough to be used as an embedded unit, meaning it can be used without the need for external components. It also has a long life, with a shelf life of over 10 years at a constant temperature.

In addition to its long life, the P51-75-S-D-MD-4.5V-000-000 is robust and highly accurate, providing reliable readings in extreme pressure environments. It’s also designed to be highly immune to mechanical shock and vibration, making it suitable for monitoring emissions in dynamic applications. Lastly, its temperature compensation ability makes it useful in applications requiring PLC control.

Conclusion

The P51-75-S-D-MD-4.5V-000-000 is a robust and reliable smart pressure sensor, transducer, and gauge. It measures and displays both positive and negative pressure differentials, has a long shelf life, and is suitable for extreme environment as well. With its low power consumption and temperature compensation, the P51-75-S-D-MD-4.5V-000-000 provides a cost-effective solution for a range of applications such as HVAC, energy efficiency, and emissions monitoring.
