MLH500BSD08E pressure sensors are designed to be used as transducers when measuring pressure, typically in applications such as automotive, HVAC and industrial processes. They are also suitable for use in gas and liquid temperature sensing applications in aerospace and medical instrumentation.

The MLH500BSD08E pressure sensor comprises of a stainless steel diaphragm and a piezoresistive sensing element. The diaphragm is a resilient, curved metal plate that is supported in the middle and clamped tightly at the edges, allowing a flexible deformation when pressure is applied. The special shape of the diaphragm ensures accurate and repeatable pressure measurements and can be adjusted to suit the application.

The piezoresistive sensing element is a semiconductor material, usually silicon, that changes resistance when pressure is applied. The electrical resistance of the sensing element varies depending on the amount of pressure applied and this change is utilized to measure the pressure. This is done by passing a known current through the element and measuring the resulting voltage. The greater the resistance, the lower the voltage. The voltage is then converted to a pressure value by the instrumentation.

The MLH500BSD08E pressure sensor can measure both positive and negative pressures in both liquid and gas applications. It also has a wide pressure range with pressure sensitivity of 0.08% between 0-1000 mbar and 0.1% between 0-500 mbar. Additionally, it offers excellent long-term and temperature stability (<0.2% fluctuation) over a wide range of pressures and temperatures (-40°C to +125°C).

For an accurate and reliable pressure measurement, the MLH500BSD08E pressure sensor must be combined with appropriate electronics and sealed with an environmental protection. The most common environmental protection is the use of epoxy potting compound. Application-specific protection jackets, such as diaphragm protector caps are also available depending on the physical, electrical and environmental conditions of the measured pressure.

Overall, the MLH500BSD08E pressure sensor is a reliable and accurate choice for various pressure sensing applications across a wide range of industries. It provides a precise measurement of pressure and temperature, along with excellent long-term and temperature stability. It is also highly customizable, allowing for different environmental protection and pressure ranges to suit the specific application.
