Model PG43SA-D Diaphragm Pressure Gauge Flush
Brand: WIKA Alexander Wiegand SE & Co. KGThe model PG43SA-D 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.
Features- Integrated diaphragm element monitoring with status display (patent, property right: e.g. DE102016005568)
- Two barriers for secure separation of the process from the atmosphere
- Mechanical pressure transmission without transmission fluid
- Completely autoclavable, suitable for CIP and SIP
