Differential pressure transmitter FDA 602 D • 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. Medium-pressure version Technical Data: Standard pressure range (maximum measurable pressure per pressure connection), overload, differential pressure range. See versions listed below. Storage / operating temperature -40 to +100 °C Compensated standard range -10 to +80 °C Error margin <0.05 % typical, <0.1 % max. of final value to standard pressure range (linearity + hysteresis + reproducibility + temperature error) Pressure connections G1/4“ thread, female Material in contact with medium Stainless steel, 316L, ALMEMO® connector Output 0 to 2 V Electrical connection Binder plug, including ALMEMO® connecting cable, 2 meters with shielded cable Protective class IP 65 Low-pressure version 475 grams Medium-pressure version 750 grams 11/2025 • We reserve the right to make technical changes.
