DMK 458 - Pressure transmitter for marine and offshore


The pressure transmitter DMK 458 has been developed for marine and offshore applications. In addition to thread connections, different flush versions are available, which are especially suitable for pasty, viscous, and polluted media.

Due to the capacitive ceramic sensor which is optionally available in Al2O3 99.9 %, the DMK 458 shows an outstanding accuracy as well as a high overload and temperature resistance.
