DFI 1550/1650 - DIGITAL FORCE INDICATOR

he DFI 1550 and 1650 are self calibrating microprocessor based
six-digit transducer indicators. This versatile instrument will

T

instantly self-calibrate with any Cooper transducer equipped
with the “Sure Cal Signature” option. One to four independent
transducer channel cards are available. Transducers previously
purchased may be used by purchasing the In-Line module. Manual
calibration of the DFI 1550 or DFI 1650 is done via the front panel
menu. An auto-zero circuit will zero the indicator when no load or
pressure is applied to the transducer. Standard outputs include RS-232
and 0-5 volt analog output.
