DIFFERENTIAL PRESSURE TRANSMITTER
The SST77B transmitters measure differential pressure with spans from 1,125 to 20000 mbar with a static pressure up to 200 bar. The pressure measuring element is a piezoresistive sensor. It is possible to choose a variety of sensors to satisfy all process conditions. The Spriano measuring cell contains the sensor and transmits pressure to the electronics. Based on these readings the microprocessor generates the 4-20mA analog output .two wires system and displays the pressure measurement on the LCD.
