EcoFit CPA640

Summary

Product identification

Ecofit CPA640 is a universal compact assembly for the installation of 120 mm sensors with Pg 13.5 thread into NPT process connections. It is designed for permanent installation in water and process applications.

Application

The assembly is intended for use in:

• Wastewater treatment plants
• Water treatment
• Condensate treatment
• Cooling water circuits

Operating limits

• Maximum pressure: 10 bar
• Temperature/pressure ratings vary by material:
  • Stainless steel 1.4404/1.4435 (AISI 316L), MONEL: Up to 10 bar and 140°C (284°F)
  • PVDF: Up to 6 bar and 100°C (212°F)

Mechanical construction

Design and dimensions

The assembly is available in versions with NPT ½", NPT ¾", NPT 1", and M25x1.5 process connections.

• Sensor insertion length: 120 mm (4.72 in)
• Thread for sensor: Pg 13.5
• Approximate weight: 0.1 to 0.3 kg (0.22 to 0.66 lbs) depending on version.

Materials

• Adapter body:
  • PVDF (for CPA640-A/C/E/G***)
  • Stainless steel 316L (1.4404/1.4435) (for CPA640-B/D***)
  • MONEL (for CPA640-I***)
• Sealing ring: Available in VITON (FKM), EPDM, CHEMRAZ, KALREZ.

Process connections

The assembly is designed for installation on containers or pipes and requires appropriate process connections. Available process connections depend on the assembly version:

• CPA640-A/B***: NPT ½"
• CPA640-C/D***: NPT ¾"
• CPA640-E***: NPT 1"
• CPA640-G/I***: M25x1.5

Installation is permitted only when the process is unpressurized and the container is empty.

Measuring system

A complete measuring system typically includes:

• Ecofit CPA640 installation adapter
• Sensor with Pg 13.5, 120 mm length (e.g., Orbisint CPS11D)
• Transmitter (e.g., Liquiline CM42)
• Measuring cable (e.g., CYK10)

Accessories

Available accessories include various sensors for pH, ORP, and oxygen measurement, such as:

• pH sensors: Ceragel CPS11, Memosens CPS11E, Ceraliquid CPS41, Memosens CPS41E, Memosens CPS77E
• ORP sensors: Ceragel CPS72, Memosens CPS72E
• Oxygen sensors: Oxymax COS22, Memosens COS22E
