Industry leading customers have depended upon the reliability and performance of the SV120 Series since 1989. This series features an all stainless steel sensor in addition to an all welded construction. The SV120 Series incorporates Wasco’s proprietary manufacturing method which eliminates all leak paths. This series is a perfect switch to handle corrosive media with high accuracy and tight tolerance.
We’ve designed these switches for high purity applications such as semiconductor equipment. The SV120 Series does not contain any elastomer or O-ring. All switches are helium leak tested to ≤ 1 x 10-9 std cc/sec Helium per SEMI F1.
