Without proper protection, process fluids regularly contaminate and damage inline instrumentation. SENTINEL Diaphragm Seals, also referred to as gauge guards or gauge isolators, employ a chemically resistant diaphragm to isolate and protect system instrumentation from corrosive process fluids, freezing and slurries.

• Wide variety of gauge options with gauge accuracy of /- 2% or better full deflection
• Models available with no gauge, custom fills, and factory installed instrumentation provided by customer
• Housings are unconditionally guaranteed for life not to fail or Blacoh will replace them at no cost
• Easily installed, come in a variety of chemically resistant materials, and work in both pressure and vacuum conditions
• Protect gauges and other system instrumentation from process fluid contamination and corrosion.
• Accurately transfer process pressure without direct contact with process fluids.
• Prevent erratic surges and clogging due to solids in process fluids.
• Protect gauges from freezing and slurries.
• Ensure accuracy and reliability of pressure instrumentation when working with corrosive or solids-laden fluids.
• Reduce costs by replacing expensive gauges with low cost utility gauges.
