Capsule pressure switch W117LG

for liquidsstainless steel

The W117LG NEMA 4 Ultra Pure Stainless Steel Pressure Switches have all welded stainless steel interiors which are Helium leak checked to pass 4 x 10-9 Std cc/sec. These are the NEMA 4 rated weather-proof, liquid-resistant version of the W117G, suitable for out¬side applications or in areas of condensing humidity. Set Point Range: 0.80 to 500 PSIG The Whitman Controls W117LG NEMA 4 Ultra Pure Stainless Steel Pres¬sure Switches have all welded stainless steel interiors which are Helium leak checked to pass 4 x 10-9 Std cc/sec. These are the NEMA 4 rated weather-proof, liquid-resistant version of the W117G, suitable for outside applications or in areas of condensing humidity. These switches are used in silicon wafer ovens, numerous medical devices, and other applications where even the slightest impurities are not tolerated.
