• Plant design
• Tanks, process vats or pipes

Functions and Features

• Modular, robust, heavy-duty retractable assembly designed for harsh environments.
• Can move to measurement position with process pressures up to 10 bar (145 psi) (pneumatic actuation).
• Prevents assembly movement if a sensor is not installed (safety stop mechanism).
• Accommodates gel electrodes or pressure-overlay KCl electrodes.
• Features electrode rinsing in service position.
• Compatible with fully automated cleaning and calibration using Topcal CPC310.
• Service-friendly design.
• Locking mechanism for safety during sensor replacement.
• Pressure-tight stainless steel housing.
• Easy sensor replacement and Memosens laboratory calibration.
• Flexible material choices and modifications.
• Can be manually or pneumatically operated without interrupting the process for:
  • Separating from the process and moving to rinse chamber.
  • Rinsing with water or cleaning solution.
  • Keeping wet during operation pauses.
  • Dismounting.
  • Sterilizing.
  • Calibrating.

• Measuring Cables: CPK9, CPK1, CPK12.
• Data Cable: CYK10 Memosens.

Pneumatic Actuation

• Required Air Pressure: 5 to 6 bar (72.5 to 87 psi).
• Air Quality: Filtered (40 μm), free of water and oil.
• Air Line Minimum Nominal Diameter: 4 mm (0.16").
• Note: A pressure-reducing valve is recommended if air pressure can exceed 6 bar (87 psi). A pneumatic throttle is recommended for smoother operation.

Rinse Water Connection

• Pressure: 2 to max. 6 bar (30 to max. 87 psi).
• Requirements: Check valve and filter (100 μm) at the inlet side when using water. Chemically resistant ON/OFF valve and outlet valve recommended when using cleaning solutions with pneumatic actuation.
• Note: A pressure-reducing valve is recommended if water pressure can exceed 6 bar (87 psi).
