Diaphragm Pressure Gauges
Process Industry Series High Overpressure Safety up to 40 or 100 bar Model 432.56 High Overpressure Safety up to 400 bar Model 432.36
Pressure Gauges
Service intended Where low system pressure to be measured alternates with high pressure cycles. All stainless steel pressure gauge. Suitable for corrosive environments and gaseous and liquid media. With optional flange connection also for viscous and contaminated media. Design EN 837-3, a choice of overpressure safety is available up to 40, 100 or 400 bar, metallic diaphragm cushion provides for overpressure safety, without diaphragm hydraulically cushioned. Nominal size 100 and 160 mm Accuracy class per EN 837-3 /6 1.6 Scale ranges per EN 837-3 /5 0 ... 16 mbar to 0 ... 250 mbar (model 432.56 flange 160 mm) 0 ... 400 mbar to 0 ... 40 bar (model 432.56 flange 100 mm) or other equivalent units of pressure or vacuum. Working pressure Steady: full scale value Fluctuating: 0.9 x full scale value Overpressure safety 40, 100 or 400 bar Operating temperature Ambient: -20 ... +60 C Medium: +100 C maximum Temperature effect When temperature of the pressure element deviates from reference temperature (+20 C): max. 0.8 %/10 K of true scale value Ingress protection IP 54 per EN 60 529 / IEC 529 Pointer Adjustable black aluminium pointer Case Natural finish stainless steel case with pressure vent in case back (model 432.36 see overleaf) Upper diaphragm housing Chrome steel Window Laminated safety glass Bezel ring Cam ring (bayonet type), natural finish stainless steel
