Direct Mounted Diaphragm Seal System consists of gauge pressure transmitter with single direct mount diaphragm seal. Suitable for various kinds of pressure measurement. Explosion-proof and intrinsically safe versions available. Stainless steel wetted parts and multiple seal materials for compatibility. Compact design simplifies installation in tight spaces.
High accuracy and stability thanks to Yokogawa’s digital sensor technology. Direct-mounted diaphragm seal allows measurement of viscous, corrosive, or high-temperature media. Excellent temperature performance – minimal drift in changing process temperatures. Wide pressure ranges available to fit various industrial applications. Robust construction for harsh environments, including chemical, oil & gas, and food industries. HART / FOUNDATION Fieldbus / Profibus communication options. Advanced self-diagnostics for predictive maintenance.
