UHZ-517C70 is a double-system level instrument combined by UHZ517 magnetic level gauge and LC3144/144LD intelligent displacer level transmitter. The field level (interface) indication and measure are separated with displacer remote transmitter; this structure makes it very suitable for the high temperature high pressure, small measure range and key process liquid control and interlocking situations. The applied FOXBORO/ECKARDT intelligent displacer level transmitter is of high cost performance, high accuracy, good reliability and long service life. Tri-magnet level switch can be used for lower and upper limit alarm. Displacer level transmitter converts the level or interface signal to two wire 4~20mADC standard signal.
