      • Description

        Sensors in the 831x series measure differences in pressure between the two ports of the measuring element. Pressure differences can be measured with respect to a reference pressure, such as atmospheric, or to the command variable of a regulation system. Equally, however, it is possible to measure pressure differences within systems that have a high static pressure.

        The differential pressure transducers sense in both directions and can handle liquid or gaseous media applied to either port. Vents make installation easier. The robust design and the use of stainless steel make it possible to use the differential pressure transducer under tough operating conditions.

        Example applications:

        • Measuring flow rates
        • Clean room technology
        • Monitoring and control of heating/ventilation/air-conditioning systems

        On both pressure ports, the differential pressure transducers include a closed chamber, each with a membrane. Both membranes, like all the parts that come into contact with the medium, are made of stainless steel and are welded to create a hermetic seal against the inner space of the measuring element. Transducers with this structure are also referred to as wet/wet; it allows differential pressure of gaseous and liquid media to be measured directly. The differential pressure sensors work in both directions, i.e. either port can be the higher pressure connection. Integrated measurement amplifiers for ± 5 V or 4 ... 20 mA are offered as an option; this increases the height by 29 mm.
