Marine and Offshore Ceramic Pressure Transducer


The DMK458 is designed for continuous submersion performance for liquid measurement and level control in marine and offshore environments. This submersible pressure transducer offers long term stability, excellent thermal behavior, and accuracy of 0.25% with a 0.1% option.  The DMK458 has stainless-steel housing, ceramic diaphragm and thread connections for use in viscous, pasty and polluted applications. The DMK458 offers optional flush versions to ensure submersible performance in a wide variety of viscous media. A modular construction allows for different combinations of process connections, outputs and electrical connections available upon request.

Application Examples

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Why do we use it?

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
