- Operating Pressure: Max 10 bar (142 PSIG)
- Function Features: Integral temperature compensation for conductivity measurement; polished sanitary‑grade surface compliant with EHEDG standard; FDA‑approved wetted materials; support direct pipeline insertion and retractable installation; compatible with Yokogawa liquid analyzers.
- Performance Parameters: Temperature response time < 1 min (90% step change); conductivity measurement accuracy ±1% full scale; long‑term stability ±0.5% full scale per year.
- Material Composition: Body and electrodes: AISI 316L stainless steel; O‑ring: EPDM FDA‑compliant rubber; insulation material: PEEK polyetheretherketone; mounting adapter: stainless steel.
- Structural Characteristics: Φ19 mm cylindrical sensor body; electrode embedded structure; integral cable lead‑out; adapter‑mounting external thread interface.
- Working Principle: Two electrodes apply alternating current to measured liquid, calculate liquid conductivity by measuring resistance between electrodes; Pt1000 sensor measures liquid temperature to compensate conductivity value affected by temperature change.
- Advantage Highlights: Sanitary‑grade design suitable for pharmaceutical and food industries; high‑precision low‑conductivity measurement; corrosion‑resistant stainless‑steel material; high temperature and pressure resistance; simple maintenance.
- Applicable Industries: Pharmaceutical pure water system, food and beverage production water, semiconductor ultra‑pure water monitoring, power plant condensed water, chemical process water, boiler feed water.
- Installation Requirements: Adapter‑mount pipeline installation; ensure electrode fully immersed in measured medium; avoid bubble accumulation around electrodes; horizontal or vertical mounting allowed.
- Usage Precautions: Regular electrode surface cleaning to remove dirt and scaling; avoid strong acid‑alkali medium corrosion; sterilization strictly follow temperature‑time specifications; regularly calibrate cell constant.
