EDS7-4F Datasheet, PDF (1/6 Pages) Fuji Electric – HEIGHT TRANSMITTER

HEIGHT TRANSMITTER
DATA SHEET
FNG
This is a height transmitter utilizing an induction poten-
tiometer.
A wire rope is placed atop the gas holder whereby the
lift of the holder moves the rope which in turn rotates the
pulley. This motion is conveyed to the induction potenti-
ometer which then provides a current signal of 4 to 20mA
DC proportional to the holder lift.
FEATURES
1. High reliability
A contactless induction potentiometer is employed which
assures a long life and high reliability of the instrument.
2. Various specifications available
The transmitter can be provided with intrinsically safe
explosionproofing, various materials for its components,
an arrester, an alarm unit and other specifications.
