SST77BL 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.
LEVEL TRANSMITTER (DP)
The SST77BL transmitters measure a liquid level head with spans from 35 to 10000mbar also with a static pressure. 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.
