The SST56 transmitters, complete with diaphragm in AISI 316, measure relative pressure with spans from 0,02 2 to 401bar. 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.
