Wika Model 990.26 Diaphragm Seal with Flange Connection

The model 990.26 diaphragm seal is ideally suited for applications with small process connections.

Due to the internal diaphragm low measuring ranges can be realised. The large diameter of the diaphragm effects a lower deviation at the measuring instrument when the temperature changes.

Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary.
