SENSVISION PTC 400 – An Equivalent to the BD Sensors DMK 457

The BD Sensors DMK 457 is a ceramic pressure transmitter designed for shipbuilding, marine, and offshore applications. It is suitable for pressure measurement and hydrostatic level measurement in demanding environments, including seawater systems and ballast tanks, with nominal pressure ranges from 400 mbar to 600 bar.

The SENSVISION PTC 400 offers the same pressure range, ceramic sensor technology, corrosion-resistant material options, marine approvals, and application flexibility as the BD Sensors DMK 457, making it an ideal replacement for both new installations and existing marine systems.

The pressure transmitter DMK 457 was specifically designed for typical shipbuilding and offshore applications where reliable operation, resistance to harsh media, and compliance with marine certification requirements are essential. The SENSVISION PTC 400 is engineered to meet these same demanding requirements, providing stable, accurate, and dependable pressure measurement in marine and offshore environments.

Like the BD Sensors DMK 457, the SENSVISION PTC 400 is available with a ceramic Al₂O₃ diaphragm and an optional copper-nickel alloy pressure port and housing for seawater resistance. This makes it particularly well suited for applications such as ballast tank level measurement, seawater cooling systems, marine fluid systems, and offshore process equipment.

The SENSVISION PTC 400 holds approvals from major marine classification societies, including Lloyd’s Register, DNV, ABS, and CCS. It is also available in an Ex ia intrinsically safe version for hazardous locations involving gases and dusts.

Whether you are replacing an existing BD Sensors DMK 457 or specifying a pressure transmitter for a new shipbuilding or offshore project, the SENSVISION PTC 400 provides a dependable, cost-effective solution that delivers the same performance, certification support, and corrosion resistance expected in demanding marine applications.
