Model 712.15.100, 732.15.100 Differential Pressure Gauge
Brand: WIKA Alexander Wiegand SE & Co. KGThese high-quality gauges are characterised by their compact and robust design and are primarily used for level measurement on liquid gas tanks.
An optional valve manifold for flange mounting with working pressure indication makes the central measurement of both level and working pressure possible in the one instrument.
The level display can be supplied with an optional, integrated 4 … 20 mA, 2-wire transmitter. Switch contacts for level and working pressure, as well as a transmitter for the working pressure can be retrofitted on site.
Features- Differential pressure measuring ranges from 0 … 80 mbar to 0 ... 1725 mbar.
- High working pressure (static pressure) of 50 bar.
- Overpressure safety either side up to 50 bar.
- Very compact design.
- Optionally compact valve manifold with working pressure indication.
