Gekko Photonics / Spectrally X1 / Probe insertion sequence
How it works

Service the probe without depressurizing the line.

A full-port ball valve and a retraction chamber let the optical window be cleaned while the pipeline stays under pressure. Eight steps, from insertion to re-insertion.

Gekko Photonics — Spectrally X1 INLINE — illustrative schematic

Full-port ball valve

Rotated 90 degrees it isolates the process, so the window can be cleaned in the retraction chamber while the line stays under pressure.

Retraction chamber

Holds the probe above the closed valve, with internal seals around the shaft and rinse ports for in-line cleaning.

Gland

Tightened around the probe at measuring depth to seal against process pressure, loosened before the probe moves.

Window cleaning

Rinse medium flushes the retraction chamber and cleans the window in line, with the probe in place and the process isolated.
