定义
A complete pH sensor assembly designed for integration into automated pH monitoring and dosing systems, consisting of a glass electrode, reference electrode, temperature sensor, and protective housing. This component provides continuous, real-time pH measurement in industrial processes with high accuracy and reliability, enabling automated chemical dosing control.
工作原理
The pH sensor assembly operates on the potentiometric principle, where the glass electrode develops a potential proportional to hydrogen ion concentration. The reference electrode provides a stable reference potential. The combined electrode potential is measured against the reference, with temperature compensation ensuring accurate pH readings across varying process conditions.

Glass electrode: pH-sensitive glass membrane (typically lithium silicate glass)Reference electrode: Ag/AgCl or calomel reference system with KCl electrolyteBody: Chemical-resistant materials (PPPVDFor PEEK)Junction: CeramicPTFEor glass fritCables: Shieldedchemical-resistant cable with IP67/IP68 rating
Accuracy
±0.01 pH
Cable Length
Standard 5m, options up to 20m
Output Signal
4-20 mA or digital (Modbus, Profibus)
Response Time
<30 seconds to 95% of final value
Pressure Rating
Up to 10 bar
Measurement Range
0-14 pH
Temperature Range
0-100°C
Process Connection
3/4" NPT, G1/2", or flange mount
标准
ISO 15839DIN 19261IEC 60746ASTM D1293

常见问题

How often should pH sensor assemblies be calibrated?

Industrial pH sensors should be calibrated at least once per week for critical processes, or according to manufacturer recommendations. Two-point calibration using pH 4.01 and 7.00 or 10.01 buffer solutions is standard practice.

What maintenance is required for pH sensor assemblies?

Regular maintenance includes cleaning the electrode surface, checking and refilling electrolyte solution, replacing junction materials as needed, and verifying temperature sensor accuracy. Protective sleeves should be inspected for cracks or contamination.

Can pH sensor assemblies handle high-temperature processes?

Yes, specialized high-temperature versions are available with reinforced glass membranes and heat-resistant materials that can withstand temperatures up to 130°C, though standard models typically operate up to 100°C.
