PG43SA-D Diaphragm Pressure Gauge

The WIKA PG43SA-D pressure gauge has been designed specifically for the highest safety requirements in the pharmaceutical and biotechnology industries. Through its patented diaphragm 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 pressure measuring instrument ensures the reliable separation of ambience and process.

The diaphragm pressure gauge transmits the pressure, purely mechanically and without transmission fluid, from the process to the pressure element. Due to their thickness, the diaphragm elements are very robust and have high overpressure safety, ensuring a safe pressure measurement without any risk of contamination.

The flush welded diaphragm element in conjunction with the aseptic process connections enables a dead-space free connection to the process. The independent pressure display, needing no external power, finds applications with the processing and transport of high-quality and critical media, for example on portable tanks.WIKA’s PG43SA-D in hygienic design can be used for CIP (cleaning in place) and SIP (sterilisation in place) and in wash-down areas, or it can be completely sterilised in an autoclave. The measuring instrument can thus be cleaned reliably and time-efficiently. The model PG43SA-D conforms to the 3-A Sanitary Standard and is certified by EHEDG.
