Evidence Notes
Submersible solid-state chlorine architecture for cooling water
The v1 applications place this sensor in cooling towers, remote sites, process water, and low-service free-chlorine trending. The architecture uses an IP68 solid-state electrode and controller output for aqueous chlorine monitoring where in-tank or remote installation is preferred.
Technical & Engineering Details
Secondary engineering detail — expand each topic for the full measurement, envelope, sample-system, calibration, and maintenance information.
01 Measurement Principle
How the measurement is bounded
Solid-state electrochemical free-chlorine measurement uses a submersible electrode and panel electronics for in-tank or remote aqueous monitoring.
Requires
- Submersible installation kept within the IP68 sensor boundary
- Calibration interval set within the stated 30-90 day range according to water quality
- Temperature-compensated output checked against site water conditions
Interferents and Limits
- Biofilm or fouling on the solid-state electrode can change response
- Cooling-tower chemistry and biocide programs can require method review
- pH and oxidation-reduction chemistry can affect free-chlorine interpretation
- Regulatory DPD reporting duty may require a colorimetric method path
- Water temperature, pressure, flow, and pH numeric ranges are not stated in v1 source data
- Chlorine-air area monitoring is outside this aqueous sensor boundary
02 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Operation without electrode fouling review in cooling-tower or remote-site duty
- Regulatory reporting duty without method and verification review
- Use as a chlorine-air area monitor
03 Sample System Boundary
Sampling mode, conditioning components, and exclusions define where the analyzer responsibility ends and the sample system begins.
- IP68 submersible solid-state electrode
- controller panel
- temperature-compensated output
- Not a stack, duct, or ambient-air chlorine detector
04 Calibration & Validation site-specific
Calibration method, interval, and traceability are shown only when structured data is available.
Zero / Span Method
Calibration workflow is site-specific; v1 states a 30-90 day calibration interval
Interval
30-90 days
05 Maintenance & Spares site-specific
Tasks, consumables, and access items are shown only when structured maintenance data is available.
- Inspect solid-state electrode for fouling or coating in cooling-water duty
- Verify calibration interval within the stated 30-90 day range
- Check controller output after in-tank sensor service
- Review water chemistry before using the same calibration interval at a new site
- Solid-state electrode service parts
- calibration standards
