Digital Pressure Transducer
The compact pressure transmitter utilizes a cutting-edge force-sensitive chip renowned for the pressure sensor transmitters' high accuracy and stability, coupled with a stainless steel isolation diaphragm. This combination enables the device to achieve temperature and linear compensation, as well as providing signal amplification, inverse polarity protection, and current limiting in case of pressure overload. These functionalities are achieved through meticulous laser resistor trimming and advanced thick-film technology.
