Gas Density Transmitter - GD10-FT

Brand: WIKA Alexander Wiegand SE & Co. KG

Model GD10-FT features a gas density transmitter with additional temperature sensor and a temperature transmitter integrated into a special connection head.

It functions fully as a standard GD10 gas density transmitter, however, the dual output allows to compensate individual tank temperature disbalance effects.
Features
  • 4 ... 20 mA density and Pt100 temperature readout.
  • Includes additional temperature sensor.
  • Output: 1 x 4 ... 20 mA, 1 x Pt100.
  • Wetted parts made of stainless steel, fully welded.
  • High EMI performance, excellent long-term stability.
