Features
SS420 series flush mount pressure transmitter is developed with a 3.3V power supply, giving a 0 to 3V or 0 to 2.5V analog signal. It is an oil-filled silicone sensor designed using piezoresistive technology, and it works following the piezoresistive effect. Pressure applied by the process media is hydraulically transmitted from the flexible diaphragm through the filled fluid between the diaphragm and the instrument to the pressure element. The transmitter is very rugged and robust. Flush port connection with stainless steel 316L material. A ring on the diaphragm. It offers excellent long-term and stable performance throughout the complete range of pressures from 0.1 bar up to 1000 bar.
