Point AReaction outlet
The concentration leaving the reaction step, read on the clarified liquor. Where the stream carries suspended sulfur, the point moves downstream of filtration.
Hydrite Ag & Sulfur / Where it fits
Where it fitsFrom a spectrum in the liquor to a tag in your DCS.
Inline means the probe sits in the line or vessel and measures the medium directly. The analyzer cabinet sits near the measurement point, at a location agreed in the feasibility report, and each value reaches the control system seconds after the spectrum is taken.
01Installation points
Three candidate points at each thiosulfate plant.
One cabinet serves two points as standard, with more on request. The feasibility report recommends which two come first at each plant.
Point A
Point BStorage tank recirculation
Homogeneity and final concentration of the volume that feeds load-out, read in the recirculation loop over a full turnover.
Point CLoad-out line
A reading on a load-out line that stays liquid-filled, stored with a time stamp for each load.
Pressure, temperature and location of each candidate point are checked in the feasibility workshop against the probe rating: up to 16 bar and −40 to +125 °C. The probe connects to the cabinet by optical fiber, on a flange, Tri-Clamp or retractable holder.
02Self-cleaning probe
The window stays clean on a timed cycle.
Thiosulfate liquors are clear, and any optical window in a process line still collects deposits over a campaign. The retractable module takes the probe out, rinses the window and returns it, on a schedule set for your line.

Return
The window is cleaned on a retract, rinse and return cycle while the analyzer keeps its place in the line. Calibration runs automatically against a reference built into the probe.
03Into your control system
A value in the control system, with the spectrum stored beside it.
Each reading arrives as an ordinary process tag.
Modbus
Into the PLC or DCS
Thiosulfate, sulfate and homogeneity values as tags, with alarm limits set in Spectrally OS.
PASS/FAIL
Flags on the grade
Each spectrum is classified against the grade specification, and the flag goes to the same control system.
Record
A file per load
Results and raw spectra stored locally, exportable as CSV, PDF or raw data, with role-based access.
04Path to the line
From your samples to a value in the DCS in 3 to 5.5 months.
The steps are the same for every liquor; the timing for your line is set in the feasibility report.
Feasibility workshop
A working session with your technology, production and quality people: measurement points, analytes and the KPIs that matter on your line.
about 3 hoursFeasibility study
We measure 3 to 5 representative batches or samples in the Gekko lab, build the calibration models and quantify the gain as a documented scenario on your data.
about 4 weeksInstallation
Probe and cabinet on the selected line, validation against your laboratory, operator training and integration with your control system.
6 to 12 weeksScale-up
Further measurement points once the first one runs on its model, on the same software layer and the same service team.
3 to 5.5 months to the first running point05What the plant provides
A short list, agreed in the feasibility report.
| People for the workshop | Technology, production and quality, for about three hours |
| Samples | 3 to 5 representative batches or samples, with the lab values you already have for them |
| Process connection | Flange DN32/40/50 PN16, ANSI 1¼″/1½″/2″ Class 150, NPT male 1¼″ or Tri-Clamp 1½″/2″, or a custom design; retractable process holder where the probe has to come out under process conditions |
| Power at the cabinet | 230 V AC, 50/60 Hz, grounded; 300 W |
| Cabinet location | 0–45 °C ambient, 20–70% RH non-condensing |
| Control system | A Modbus endpoint in the PLC, DCS or SCADA, scoped with your automation and OT team |
| Operators | One training session for up to 10 people, on site or online |
| Point data | Pressure, temperature and area classification of each candidate point |
