DESCRIPTION
The model PG43SA-D diaphragm pressure gauge has been designed specifically for the highest safety requirements in the pharmaceutical and biotechnology industries. Through its patended 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 points is not required.
In the event of a diaphragm rupture, a second barries in the instrument ensures the riliable seperation of the environment and the process.
The diaphragm pressure gauge transmits the pressure, purely machanically and without transmission fluid, from the process to the pressure element. Due to their thickness, the diaphragm element are very robust and have high overpressure safety, ensuring a safe pressure measurement without any risk of contamination.
The flush welded diaphragm element in conjuntion with the aseptic process connections enables a dead-space free connection to the process. The independent pressure display, needing to external power, finds applications with the processing and transport of high-quality and critical media, for example on portable tanks.
The 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 reliably and time-efficienctly. The model PG43SA-D conforms to the 3-A Sanitary Standard and is certified in accordance with EHEDG.
A variety of 3.1 and 2.2 certificates are available for GMP-Compliant documentation, such as a material certificate of the list of single measured values.
