Description
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.
