FILTER/LAG TRANSMITTER

(field-programmable)

Functions & Features

• Providing various filter functions which eliminate

unnecessary elements in the input signals

• Microprocessor based

• On-site calibration via hand-held programmer PU-2x

• Field-programmable input range

• Isolation up to 2000 V AC

• High-density mounting

Typical Applications

• Level control; eliminating drifts in the input signal caused

by pumps
