Model DSS10T High Quality Pressure Sensor with Mounted Diaphragm Seal
Brand: WIKA Alexander Wiegand SE & Co. KGDue to its design, the DSS10T can be used universally. A replacement of the lower body is possible (e.g. when changing the process connection) without having to carry out modifications on the diaphragm seal system.
The DSS10T is ideally suited for demanding measuring tasks and achieves a very high accuracy. It is characterised by its robust design and can be used for a multitude of applications.
Mounting of the diaphragm seal to the measuring instrument is made via direct mounting as standard.
The DSS10T is particularly well suited for aggressive or hot media. This instrument is mainly geared to applications in the process industry.
Features- Process connection with thread for direct threaded connection.
- Version with internal diaphragm.
- Diaphragm seal parts screwed together.
- Universal application.
