Detailed content
- Technical Specifications:
- Model code: FU20‑10‑T2‑NPT
- Measurement parameter: pH value
- Thread standard: NPT 3/4″ process connection thread
- Cable type: Built‑in T2‑type cable connection
- Electrode length: 10 mm insertion depth variant
- Functional Features: Continuous pH monitoring, liquid junction self‑cleaning capability, built‑in temperature compensation sensor, high‑pressure resistance
- Performance Parameters:
- pH measurement range: 0–14 pH
- Operating temperature range: 0 °C to 85 °C
- Maximum operating pressure: 1 MPa (10 bar)
- Response time: ≤15 s for 95% step change
- Reference system: Silver‑silver chloride (Ag/AgCl) reference electrode
- Material Composition: Borosilicate glass pH‑sensitive membrane, PTFE liquid junction, epoxy resin body, stainless steel internal components
- Structural Features: Submersible/insertion‑type structure, NPT threaded process fitting, integrated temperature sensing element
- Working Principle: Glass membrane detects hydrogen‑ion activity in process liquid; potential difference between pH‑sensitive glass electrode and reference electrode generates electrical signal proportional to pH value; built‑in temperature sensor compensates temperature‑induced measurement deviations
- Advantages: Stable long‑term measurement, high chemical resistance, easy calibration, wide process compatibility, low maintenance requirements
- Applicable Industries: Water and wastewater treatment, chemical processing, food and beverage production, pharmaceutical industry, power plant water chemistry monitoring
- Installation Requirements: Insertion installation into process pipelines/tanks via NPT thread; maintain full immersion of sensing tip in measured liquid; install with cable protection against mechanical damage
- Usage Precautions: Avoid dry storage of electrode long‑term; regular calibration with standard buffer solutions; prevent damage to glass membrane from impact or abrasive substances
