These transmitters are exclusively suitable for dry, clean and nonaggressive gases. Measuring principle The pressure is measured via a sensitive diaphragm, which is adapted to the pressure range, or a capsule element for absolute pressure ranges. An inductive system generates a linear signal which changes in proportion to the prevailing pressure. Applications This transmitter has mainly been designed for HVAC, filtering, dedusting and clean room applications as well as for the medical industry. For applications, in which switching functions are additionally required, pressure transmitters with 3-/4-wire systems can be equipped with up to two switch contacts. For each switch contact a potential-free change-over contact is available. For the local readout the measured values can optionally be equipped with a 3 -digit LC display. For flow measurements by means of a standard orifice plate a special design with an output signal calculated by rootevolution is available for 3-/4-wire systems. With this design it is possible to adjust the suppression of creeping quantities by means of potentiometers in the range 0 ... 10 %.
