Pulp & Paper Diaphragm Seal Gauge

Diaphragm Seals (Pulp & Paper Type) are designed for pressure measurement in applications involving highly viscous, fibrous, or clogging media such as pulp, slurry, and chemicals. The seal isolates the pressure instrument from the process media using a welded diaphragm, ensuring accurate measurement while protecting the instrument from blockage, corrosion, and contamination.
