Wika Model PG43SA-D Diaphragm Sanitary Pressure Gauge

Test Product

The model PG43SA-D diaphragm pressure gauge has been designed specifically for the highest safety requirements in the pharmaceutical and biotechnology industries.

Through its patented diaphragm element monitoring, the risk of an undetected rupture of the diaphragm is eliminated since a red warning dot is immediately displayed on the dial. If this point on the dial remains white, then the pressure element is intact and cost-intensive maintenance on the measuring point is not required. 

In the event of a diaphragm rupture, a second barrier in the instrument ensures the reliable separation of the environment and the process.
