Pressure Sensors and Transducers - MLH100PGD14B Application Field and Working Principle

Introduction

Pressure sensors and transducers are important components in instrumentation and control systems. Pressure sensors and transducers convert a physical pressure or displacement into an electrical signal, enabling a wide range of applications, from measuring temperature and air pressure to controlling fuel delivery in internal combustion engines. In this article, we will discuss the application field and working principle of the MLH100PGD14B pressure sensor.

Application Field

The MLH100PGD14B pressure sensor is designed primarily for medical applications, such as measuring blood pressure in patients. In addition, it can be used to measure fluid flow rate and pressure. It can also be used in industrial and automotive applications to measure various types of liquids, gases, and other non-toxic substances.The MLH100PGD14B pressure sensor is highly resistant to environmental conditions and is waterproof, making it ideal for a variety of general-purpose applications, such as water level sensing, input pressure sensing, and pressure gauging. It can also be used to measure gas, liquid, and vapor pressure in chemical processing, pharmaceutical, and oil & gas industries.

Working Principle

The working principle of the MLH100PGD14B pressure sensor is based on the Wheatstone bridge principle. It consists of four transducers in a configuration known as a Wheatstone bridge. The transducers are connected in such a way that the electrical output is proportional to the input pressure.The pressure sensor has two sides, the wetted side and the sensing side. The wetted side is exposed to the pressure to be measured, and the sensing side is connected to an amplifier circuit. The amplifier amplifies the pressure signal and converts it into an electrical output. The output is then used by the sensor to convert the pressure into an analog electrical signal.

Conclusion

The MLH100PGD14B pressure sensor is a highly resilient, waterproof device designed for a variety of medical and industrial applications. It is capable of measuring the pressure of liquids, gases, and other non-toxic substances. It works by converting the input pressure into a proportional electrical output using the Wheatstone bridge principle.
