MLH500PSL09A

Pressure Sensors, Transducers

The MLH500PSL09A is a pressure sensor/transducer, designed to convert pressure into an analog electrical signal. It utilizes a pressure port with a 5/16-24"-18UNF thread and has an output range of 0-2 ​Volts. This model has a temperature range of -40 to +85 °C and a pressure range of -15 to +73 PSI. It is able to operate at an accuracy of ±0.25% and features an IP67 protection rating.

Applications

The MLH500PSL09A is commonly used in industrial and commercial applications to measure the pressure in gas and liquid handling systems. It is also frequently used in automotive applications. This pressure sensor can be used to determine the pressure of a system, allowing the user to adjust the system accordingly. It is also useful for determining the pressure of air and fuel, allowing for better fuel economy and improved efficiency.

Working Principle

The MLH500PSL09A pressure sensor employs the piezoresistive effect to measure pressure. The piezoresistive effect occurs when a material changes its electrical resistance under mechanical stress, usually due to the presence of a force on the material. The MLH500PSL09A is made up of a ceramic diaphragm with a thin layer of resistive material on top and a Wheatstone bridge circuit underneath. When pressure is applied to the diaphragm, it causes the resistive material to strain, altering its resistance. This change is measured by the Wheatstone bridge and is then converted into an electrical signal. This electrical signal is then sent to the user. This signal is proportional to the pressure applied, allowing the user to accurately measure pressure.

Conclusion

The MLH500PSL09A pressure sensor is a versatile and robust device that is able to measure the pressure of a variety of fluids. It is commonly used in industrial and automotive applications to accurately measure pressure. By employing the piezoresistive effect, the MLH500PSL09A can measure pressure and produce an analog electrical signal proportional to that pressure.
