    SST79B series SMART level transmitters are microprocessor based instruments that combine the analog signal advantages 4-20mA together with the flexibility of digital communication using HART® protocol. They can be remotely configured by a universal hand held terminal (HHT) or by a PC with a dedicated interface. Moreover, it is possible to locally configure the instruments (zero and span) by means of 4 push buttons and to display the data on the wide LCD display. The transmitter SST79B measures levels of liquids in open tanks at atmospheric pressure.



    The SST79B comprises two main elements: the immersion pressure sensor and the electronic module connected by a cable of variable length. 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.
