MLH100BSD14A

The MLH100BSD14A is a pressure transducer with integrated capacitive sensing technology. It has a wide range of applications in a variety of industries, including automotive, HVAC, medical, energy, process control, and industrial automation.

The MLH100BSD14A is designed to detect and measure pressure in an environment ranging from -40°C to +85°C, featuring a highly accurate, linear output and excellent long-term stability. Its compact design makes it suitable for integration into compact systems as well as large scale installations.

The technology used in the MLH100BSD14A provides high accuracy over a wide temperature range. This is achieved through the use of two separate reference cells on the die circumference that cancel out slight changes in the operating temperature. The output of this transducer is a differential voltage signal, thus providing significant noise immunity.

The MLH100BSD14A has a wide range of applications, such as controlling pressure in HVAC systems, monitoring pressure in hydraulic systems, and measuring static pressure in industrial processes. It is compatible with standard 5V power supplies and can be used with a variety of analog-to-digital converters for monitoring and data logging in real time.

The working principle of the MLH100BSD14A is based on the capacitive measurement principle. A thin-film capacitor is embedded in the silicon die of the transducer which is responsive to externally applied pressure. The Internal reference capacitor creates a capacitance bridge, allowing for superior temperature compensation and thus high accuracy over a wide range of temperatures. When pressure is applied, the capacitor responds with a proportional voltage in the presence of an electric field. This is in direct proportion to the pressure applied, providing a linear relationship between the pressure and the output voltage.

The MLH100BSD14A is a low-cost pressure transducer that offers a convenient and cost-effective solution for pressure measurement in many industrial and medical applications. It is highly accurate and stable, providing reliable, long-term performance. With its wide range of operating temperatures and excellent noise immunity, it is well-suited for a variety of applications requiring pressure measurement.
