Pressure transducer DMU 14 DG/FG Ex
Precision pressure transducer with EX approval


The new AFRISO DMU 14 DG/FG Ex pressure transducer is designed for electronic pressure measurement in applications requiring high measuring accuracy (< ± 0.1 % FSO) and long-term stability (< ± 0.1 % FSO/year). Due to the turn down range of 1:5 (measuring accuracy ± 0.2 % FSO), it is the ideal solution for special measuring tasks in the process industry.

The measuring instrument converts the pressure of liquid or gaseous media in the ranges from 0/400 mbar to 0/600 bar into a proportional 4-20 mA signal. The DMU 14 DG/FG Ex transducer features ATEX approval and HART communication and is suitable for temperatures of the medium of -30 °C to +125 °C and for (Ex) ambient temperatures from -20 °C to +(60)70 °C. The measuring instrument is supplied with DC 12-28 V and features a G1/2B process connection. The integrated display has main and supplementary indication. DMU 14 Ex is available with two housing versions: a stainless steel field housing (FG) for the pharmaceutical and food industries and an aluminium die cast housing (DG) for rough conditions in the process industry. The new pressure measuring instrument is optionally available without display, with other process connections and in a high temperature version up to 300 °C. The robust transducer was developed for high long-term stability and a long service life.
