Description
The Seadraulics Differential pressure sensor Model 1182 uses two absolute pressure sensors to take the differential pressure measurement indirectly, rather than measuring directly. As well as reducing costs, this differential pressure transmitter is also more robust in relation to unbalanced (one-sided) overloading.
In applications where the differential pressure is more than 5% of the maximum standard pressure range, measurement with two absolute pressure sensors offers major advantages over conventional methods of differential pressure measurement.
In order to ensure that differential pressure can still be measured exactly if the standard subsea pressure range/differential pressure ratio is high, this series also features the tried-and-tested micro-processor based technology that is used in Keller-Druck sensors. All reproducible subsea pressure sensor errors (i.e., non-linearities and temperature dependencies) are entirely eliminated thanks to mathematical error compensation.
