The pressure transmitter DMP 457 has been especially designed for rough conditions occurring especially in shipbuilding and offshore applications. All gaseous and liquid media, which are compatible with stainless steel 1.4404 (316L) respectively can be used. Sensor element is a piezo resistive stainless steel sensor with high accuracy and excellent long-term stability. In order to meet the special requirements for shipbuilding and offshore applications extensive tests had to be passed to get the Lloyd´s Register, Germanischer Lloyd (GL), Det Norske Veritas (DNV), Bureau Veritas (BV) and China Classification Society (CCS) approvals.
