DESCRIPTION
Differential Pressure Meter
Digital differential pressure transducer with analogue output / High accuracy / For differential and relative pressure measurement / Selectable measuring ranges

The Differential Pressure Meter pressure transducer has user selectable pressure ranges, selectable analogue outputs, and an optional LCD display. These differential pressure transducers are supplied via the operating network. You can reconfigure the measuring devices on-site at any time with just a few simple steps. The long-term stability is better than 0.5% based on the full measuring range. The microprocessor-controlled electronics guarantee high accuracy (± 0.5% of the measuring range).

In addition to being used in the process (to power a remote display or a regulator) as fixed or wall-mounted units, the differential pressure transducers can also be used as an on-site meter or even mobile. The optional LCD display allows on-site reading. With the help of the automatic zero setting, the measuring devices can be quickly reset on site. The analogue output can also be used in combination with the optional datalogger offered by us in the accessories. This allows you to record the differential pressure readings over a longer period of time, later transfer the stored data to a computer and analyze it there.
