TI 177F/00/en
Radiometric Level Measurement
gammapilot FTG 671
Non-invasive, radiometric limit detection
Intrinsically safe signal circuit [EEx ib] IIC /
ATEX II (2) GD
For scintillation or Geiger-Müller detector
Application
The Gammapilot FTG 671 transmitter is
designed for
• non-invasive, level limit detection
in containers - mixers, reactors,
hoppers, silos, tanks - with inflammable,
abrasive, poisonous and aggressive
bulk material and liquids, e.g. in acid
tanks, boilers, cement silos, ballast
hoppers, cyclones, cupolas, rotary
furnaces etc.. Thanks to the fact that the
measuring system is fitted externally, it
also finds application in the food
processing industry.
Gammapilot transmitters may also be
used for applications in explosion
hazardous areas, and possess
intrinsically-safe sensor circuits
conforming to EEx ib IIC, or EEx d IIC,
EEx de IIC depending on the detector.
