SMART DIFFERENTIAL PRESSURE SWITCH SERIES SSW77B
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. Thermal drift is compensated using the temperature signal generated by a PTC thermistor integrated in the sensor itself. Based on these readings the microprocessor shows the measurement on the display and command an ON/OFF signal output contact, depending by a set threshold.
