SSCSMNN250MG2A3

A pressure sensor, otherwise known as a transducer, is a device used to measure the pressure of a gas or liquid. SSCSMNN250MG2A3 is a miniature size differential pressure sensor manufactured by Sentec Engineering, specializing in measuring low air pressure (vacuum) or gas pressure in industrial, medical and commercial applications. This sensor is sensitive and accurate enough to measure pressure levels from 10inH2O to 250inH2O, reaching an accuracy of ±0.1 percent FS.

Applications

SSCSMNN250MG2A3 is a useful tool for applications requiring accurate low-pressure measurements. Examples include the following:

• HVAC and environmental control systems
• Some industrial processes, medical systems and air tools
• Automatic pump controllers
• Carbon dioxide control systems
• Gas chromatography instruments

Working Principle

The working principle of the SSCSMNN250MG2A3 pressure sensor is based on measuring the difference in pressure between two points. Its sensing elements are comprised of high-quality ceramic capacitors. The capacitors are used to measure changes in air pressure. The sensors measure the electrical charge generated by the changing air pressure. The signals are then digitized and used to accurately measure the differential pressure.

The basic components of the pressure sensor include the sensing element, the sensing circuit, a microcontroller for signal conversion, and an output port for data communication. It has special feature of reverse-polarity protection and reverse-current protection, which make it very reliable under harsh environmental conditions. It also supports SPI communication, allowing it to be configured and updated remotely. All this makes SSCSMNN250MG2A3 a versatile and accurate pressure sensor for many applications.
