Introduction

Pressure sensors, transducers, and indicators are used in a wide range of industries and applications to measure, monitor, and control pressure within systems and devices. The MLH08KPSB01B pressure sensor is a compact, industrial-grade device that is designed for industrial pressure measurements. This article will explain the application field and working principle of this device.

Application Field of MLH08KPSB01B

The MLH08KPSB01B is designed to measure absolute and gauge pressures of a wide range of fluids and gases, and can be used in a host of operations and industries. It is suitable for measuring pressure in applications involving pneumatic and hydraulic systems, wellheads, tanks, valves, engines, plants, and other equipment. It can also be installed in hospitals, scientific laboratories, and quality control systems.The device features a robust construction, offering excellent long‑term durability for industrial environments. Its output signal is voltage or 4-20mA current, and it operates over a wide temperature range of -30°C to +70°C. It is also resistant to a range of chemicals and shocks, and is highly resistant to pressure spikes and chemical corrosion.

Working Principle of MLH08KPSB01B

The MLH08KPSB01B pressure sensor is a piezoresistive device that employs a Wheatstone bridge circuit to measure pressure. A Wheatstone bridge is an electrical circuit that can be used to measure a resistor’s resistance. When pressure is applied to the sensor, it changes the resistance of the bridge, which then produces an output voltage.The Wheatstone bridge circuit is composed of four resistors, one of which is a pressure-dependent resistor. As pressure is applied to the sensor, it changes the resistance of the pressure-dependent resistor inside the Wheatstone bridge circuit, which in turn changes the output voltage of the circuit. This change in voltage is then proportional to the pressure applied.The MLH08KPSB01B pressure sensor is designed to measure gauge and absolute pressure values using an integrated static pressure port. This port can measure pressure up to 3500 psi (24.1 MPa), and is calibrated with a temperature compensation over 0-70°C.

Conclusion

The MLH08KPSB01B pressure sensor is a rugged, industrial-grade device that is designed for measuring absolute and gauge pressure values from a range of gases and liquids. It has a robust construction, and features a temperature compensation over 0-70°C. Moreover, it operates over a wide temperature range of -30°C to +70°C, and is resistant to shocks and a range of chemicals. Its output signal is voltage or 4-20mA current, and it works on a Wheatstone bridge principle, relying on a pressure-dependent resistor to measure pressure by changing the circuit\'s output voltage.
