GAL Series- Slim Submersible Transmitters with Remote Electronics
  • Low ranges from 40 mm wg to 160 m wg
  • Turndown Capabilities with Remote Electronic
  • All Welded Sensor

The GAL series packages LVDT sensor technology in three different sensors each with a remote electronic package that allows for zero and span calibration. The LG sensor has an exposed diaphragm and is suitable for use on clean liquids, liquids with suspended solids, highly viscous liquids, and slurries. The LT sensor has a recessed diaphragm protected by a plastic nose and is suitable for use on low viscosity liquids with less than 5 % suspended solids. The LM sensor has a recessed diaphragm and a protective nose cap in only a 17.6 mm diameter enclosure, which is designed for use in boreholes and other tight spaces. The LM is suitable for use on low viscosity liquids with less then 5 % suspended solids.
