• 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. Low-pressure version Medium-pressure version 11/2025 • We reserve the right to make technical changes. Technical Data: Standard pressure range (maximum measurable pressure per pressure connection), overload, differential pressure range. See versions listed below.
