Pressure sensors, also known as pressure transducers, are instruments employed to measure pressure generally in liquids and gases. The MLH500PGL01G is, specifically, a pressure transducer that is widely used in a variety of industries for countless applications. This article details the application field and working principle of the MLH500PGL01G.

Application Field

The MLH500PGL01G is capable of measuring pressure from -14.5 to 5,660 psi, and is thus widely used in applications requiring moderate pressure resistance. Typical application areas include pumps, compressors, and hydraulic systems. Its main benefit lies in its ability to work in varying temperatures as low as -40°C to 85°C, making it ideal for applications with temperature fluctuations. Additionally, the MLH500PGL01G is best suited for harsh environments, as its output includes a digital signal of duration 0- 10 ms with absolute accuracy.

Working Principle

At its core, the MLH500PGL01G works by converting changes in pressure into electrical signals. Three core components—the pressure port, membrane, and signal output—together form the operating system of the transducer. The entire setup rests on the pressure port, which is designed to pick up and measure changes in pressure directly. It is equipped with a blind hole, designed to prevent it from getting clogged with foreign materials. Meanwhile, the membrane, which is the most important feature of the device, is made up of a sophisticated combination of materials designed to enhance accuracy and durability.

When the pressure port is exposed to pressure, the membrane is pushed down a certain distance, which is then converted into an electrical signal. The signal is sent to the signal output, which is designed to monitor the changes in the device’s output based on changes in pressure. The signal output receives the electrical signal and converts it into the appropriate parameters required for display, recording, communicating, or other post-processing.

So, when the MLH500PGL01G is exposed to various levels of pressure, the port and membrane work together to create a digital signal that can be used to track and display the changes in pressure. By combining ease of use with accuracy, the MLH500PGL01G pressure transducer is the ideal choice for many applications.
