The MLH250BSB10A is a pressure sensor and transducer device designed to measure the pressure of gases or liquids, linearize the results, and output signals in various formats. It is a highly reliable device which utilizes the latest advances in electronic components and design, thus providing customers with the highest quality and accuracy.

Overview

The MLH250BSB10A is a single-element pressure sensor and transducer device. It consists of a sensing element and a circuit for signal conditioning and processing. It is constructed from a thick-film ceramic element for pressure sensing, with a diaphragm bonded to a piezoelectric diaphragm and a rear side cavity. The ceramic element is mounted on a plastic housing and sealed by an epoxy resin. The sensing element is covered by a capsule that seals and protects the entire structure. The signal processing circuit is formed on a printed circuit board.

Application Field

The MLH250BSB10A is suitable for applications such as pressure and force measurement in medical equipment, industrial process control, consumer electronics, automotive, and aerospace. This simple yet precise device is ideal for both dynamic and static pressure measurements. Its excellent accuracy and repeatability make it suitable for a wide range of applications requiring the highest level of accuracy.

Working Principle

The MLH250BSB10A pressure sensor and transducer follows a piezoresistive pressure measurement principle. A thick-film ceramic element, with a diaphragm bonded to it and a rear cavity, is used to sense the pressure. When pressure is applied to the sensing element, the diaphragm causes a change in electrical resistance of the ceramic material. This resistance change is converted by the device into a voltage or current output signal. The signal is amplified and converted to a form that can be read by a controller or other device.

Output Options

The MLH250BSB10A is equipped with a range of output options that can be used depending on the application requirements. The device offers both ratiometric and true differential outputs with ranges of 0 to 10V and 0 to 1V respectively. It is also available with a 4-20mA constant current output option. The accuracy and repeatability of the output signals is excellent, with a maximum linearity error of 0.3%.

Features and Benefits

The MLH250BSB10A provides numerous advantages compared to other pressure sensors and transducers. These include a wide operating temperature range between -40°C and 120°C, a long lifetime of up to 500,000 cycles, EMC compatibility, and excellent chemical resistance. The device is also RoHS compliant and is designed to meet both UL and CSA standards. It is available with various connectors and is configurable with various output options, making it suitable for a wide variety of applications.
