The new model PG43SA-D diaphragm pressure gage (photo) features integrated diaphragm monitoring, and thus eliminates the risk of an undetected diaphragm rupture. The patented monitoring functionality enables the immediate indication of any rupture in the diaphragm element via a red warning dot on the dial. Thus, the otherwise usual, regular removal of the instrument to check the measuring element is no longer required. Even in the event of a diaphragm rupture, the process risk is minimized — a second barrier in the pressure-measuring instrument reliably maintains the hermetic separation between the atmosphere and the process. Furthermore, the purely mechanical pressure transmission, which excludes the risk of any contamination through the transmission fluid, and the high overpressure safety enable the PG43SA-D to be used in processes with sensitive or critical media. — WIKA Alexander Wiegand SE & Co.
