Technical data and functions

This measures the differential pressure in liquid and gaseous media indirectly using two absolute pressure sensors.
This makes it less expensive but more robust with respect to asymmetrical overload.
The differential pressure range should be at least 5% of the standard pressure range.
Each side of the sensor incorporates two pressure connections. The transmitters can thus be used easily and conveniently in pressure pipes.
It incorporates a high-speed, high-precision microprocessor.
All reproducible errors affecting the pressure sensors, i.e. involving non-linearity and temperature dependency, can be completely eliminated by means of mathematical error compensation.
