Liquiline To Go CYM292-Ex-CYM291

Summary

Product identification

• Product: CUA261 Adapter
• Purpose: For installing process photometers in VARIVENT process connections (N 68 mm).
• Compatibility: Designed for optical sensors such as OUSAF44, OUSAF12, OUSAF22, OUSAF46, and OUSTF10.
• Nameplate Information: Includes manufacturer identification, order code, extended order code, serial number, ambient and process conditions, and safety information.

Intended Use

The CUA261 adapters are intended for the installation of specific optical sensors within pipes featuring VARIVENT process connections (N 68 mm). They are designed for operation in pressurized systems. Any other use is not permitted and may pose risks to personnel and the equipment.

Operating Limits

• Process Temperature: 0 to 135 °C (32 to 275 °F). Users must also comply with the maximum permitted process temperature of the sensor.
• Process Pressure: Maximum 11 bar (15 psi), absolute, at 25 °C (77 °F).

Mechanical / Hydraulic

• Dimensions: Detailed dimensions are provided for adapters compatible with OUSAF4x, OUSAFx2, and OUSTF10 sensors, including variations for different pipe diameters and path lengths. See figures 3-6 in the original document for specific measurements.
• Weight:
  • Adapter complete with flow assembly and OUSAF44: Approx. 4.4 kg (9.3 lbs)
  • Adapter complete with flow assembly, without photometer: Approx. 3.0 kg (6.6 lbs)
  • Individual adapter: 0.4 to 0.6 kg (0.9 to 1.3 lbs) depending on version.
• Materials:
  • Adapter: Stainless steel 1.4404/1.4435 (AISI 316L)
  • Window ring: Stainless steel 1.4404/1.4435 (AISI 316L)
  • Screws and circlips: Stainless steel
  • Optical windows: Borosilicate, quartz, sapphire
  • Window snap ring: PTFE
  • Seals: FFKM FDA, silicone FDA, EPDM FDA, FKM FDA
  • Relief valve (optional): PVDF, silicone O-rings

Mounting and Installation

• Mounting Requirements:
  • Ensure optical windows are fully immersed in the medium.
  • Avoid installation positions where air bubbles can form.
  • Install the flow assembly upstream from pressure regulators.
  • Refer to specific installation position recommendations (Figures 1 and 2).
• Air Purge: An optional air purge function is available using dry air or nitrogen. The purge gas should be clean and dry (ultra zero air). Optimum pressure is 0.21 bar (2.5 psi) at room temperature for the modified window ring.
• Installation Procedure: Involves opening a VARIVENT process connection, inserting the adapter, securing with a clamp connection, and screwing on the photometer sensor.

Maintenance

• Maintenance Schedule: Intervals depend on the specific application and medium.
• Key Tasks:
  • Replacement of optical windows (only if damaged).
  • Replacement of O-rings in contact with the medium.
• Procedure: Detailed steps are provided for removing and replacing optical windows and seals, emphasizing the need for uniformity and proper tightening. Genuine spare parts are recommended.

Repair

• Concept: Modular design allows for repairs by the manufacturer's Service Department or trained users. Only original spare parts should be used.
• Returns: Products requiring repair or calibration must be returned following specific procedures, especially if they have been in contact with medium.
