SST59B 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 SST59B measures levels of liquids in open tanks at atmospheric pressure.
