PRESSURE SENSORS

The Onyx Isolator Ring is equipped with an integral block valve and module seal.

The bottom half of the Module Seal consists of a 1⁄2” thick rubber membrane at the top of the mounting post. This provides a hermetic seal for the Isolator Ring keeping the instrument oil in and the air out.

The top half of the Module Seal is the “Stinger Fitting” a brass or stainless steel fitting with a needle projecting out of the bottom.

Replacing the gauge without compromising the integrity of the vacuum fill – and without removing the Isolator ring from the process pipe – is simple:

  1. Close the Block Valve.
  2. Unscrew the Lock Ring.
  3. Pull the gauge and stinger fitting out as a complete unit.
  4. Plug the new gauge and stinger assembly into the Module Seal.
  5. Re-tighten the Lock Ring.
  6. Open the Block Valve.

Onyx Instrumentation Manifolds

Onyx Dual Mount Instrument Manifolds are the ideal way to mount two instruments on one isolator ring. Robust 1⁄2” NPT manifolds can support multiple heavy instruments including turret case gauges, switches, and transmitters. One-piece design minimizes potential leak paths. Made from 316-stainless steel. Available in three configurations shown above, there’s an instrument manifold available for just about any combination of instruments imaginable.
