Model DPGT43.100, DPGT43.160 Differential Pressure Gauge with Output Signal
Brand: WIKA Instruments Ltd.Wherever the process pressure has to be indicated locally and, at the same time, a signal transmission to the central control or remote centre is desired, the model DPGT43 intelliGAUGE® (patent, property right: e.g. DE 202007019025) can be used.
Features- No configuration necessary due to “plug-and-play”.
- Signal transmission per NAMUR.
- Differential pressure measuring ranges from 0 … 16 mbar.
- Easy-to-read Analog display with nominal sizes 100 and 160.
- Individual, non-linear characteristic curves (e. g. x or √x for flow measurement).
