The WIKA pressure transmitters Model DP-10 have been developed for the measurement of low gauge pressures and vacuum, as well as differential pressures. These transmitters are exclusively suitable for dry, clean and nonaggressive gases.

Measuring principleThe 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.

ApplicationsThis 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 and 4-wire systems can be equipped with up to two alarm contacts. For each alarm contact a potential-free change-over contact is avail-able.

For the local indication of the measured values the pressure transmitters can optionally be equipped with a 3 ½-digit LC display.

For flow measurements by means of a standard orifice plate a special design with an output signal calculated by root-evolution is available for 3 and 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 %.
