BD | SENSORS is a medium sized family run company that sets great store by independence and sustainability.
What makes a family business strong? Or, in another way, what should a family business be based on? Because family is the foundation of a larger whole, a family business in particular must be measured upon its credibility and stability. When responsibly dealing with customers and employees, decisions have to be healthy and sustainable.
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 piezoresistive 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.
