WIKA has released the 990.38 welded diaphragm seal, a drop-in retrofit for gauges and/or seal assemblies.

The all-welded seal is capable of extending gauge life by a factor of 2.5. The seal has a tamper-resistant construction and a compact design. It is suited to tightly controlled environmental applications such as corrosive, contaminated, or heterogeneous pressure media.

A solid front/blow-out back process gauge provides greater plant safety and operator protection. The system is offered in a variety of configurations, with ranges from 0-0.6 bar to 0-90 bar.

Standard features include a process pressure gauge with phenolic resin or stainless steel case and stainless steel internals. 1/2” NPT male process connections, 316L stainless steel process wetted parts, and silicone system fill fluid are also standard. Additional wetted parts, ranges, and fill fluids are available.
