Sensor Architecture
Specialized electrochemical interface designs featuring a ground glass joint provide stable liquid contact between an internal reference half-cell and external textile process solutions. A ground glass sleeve junction utilizes a ground glass ground sleeve sliding over a matching glass stem to form a broad annular flow path. This construction resists physical clogging when immersed in dye baths containing suspended solids and unfixed pigments.
The wide surface area ensures electrical continuity in foul synthetic dye liquors where porous ceramic frits fail rapidly due to particle encrustation. High flow rates of reference electrolyte clear contaminating dyes from the junction interface continuously during online pH monitoring.
Electrolyte Flow
Reference solution flows through the precision gap under controlled positive pressure to maintain stable potential measurements. Pressure differentials force potassium chloride solution outward into the surrounding dye liquor, preventing sample ingress. Consistent velocity prevents clogging from suspended lint and chemical precipitates.
Cleaning Protocol
Periodic manual flushing clears accumulated textile residues from the glass mating surfaces. Technicians loosen the glass sleeve to purge contaminated electrolyte and remove trapped dye particles. Re-seating the sleeve restores uniform flow across the annular gap.
Operational Constraint
High consumption of internal reference solution limits continuous unattended operation in automated dye house monitoring networks. A ground glass sleeve junction requires frequent electrolyte replenishment during high-temperature dyeing cycles. Depletion of internal solution causes measurement drift and eventual signal loss.
