CDCE90000-Series

Supported Applications

The Omega CDCE-90-X Series Conductivity Cells are designed for in-line and submersible installations to measure the electrical conductivity of liquids. These sensors serve as process probes compatible with CDCN-91, CDTX-90, and CDCN-5800 series instruments.

Operating Conditions & Performance

The series covers a broad measurement envelope defined by specific cell constants and ranges:

• Cell Constant 0.01: Range of 0.01 to 100 µS (10 kΩ to 100 MΩ)
• Cell Constant 0.10: Range of 1 to 1,000 µS
• Cell Constant 1.0: Range of 10 to 10,000 µS
• Cell Constant 10.0: Range of 100 to 200,000 µS
• Cell Constant 20.0: Range of 200 to 400,000 µS

All models include PT1000 temperature compensation. Maximum operating temperatures vary by model and fitting configuration: standard fittings support up to 95 °C (203 °F) or 100 °C (212 °F), while specific configurations reach 120 °C (248 °F) or 150 °C (302 °F). Pressure ratings are listed as 6.9 bar (100 psi) for standard fittings and up to 13.8 bar (200 psi) with optional high-pressure fittings.

Configuration Options

The series offers configurable wetted materials, process connections, and housing styles to accommodate different installation requirements:

• Electrodes & Fittings: 316 stainless steel or titanium (available on CDCE-90S sanitary models).
• Insulator Materials: PTFE, CPVC, or PEEK® depending on the cell constant and temperature rating.
• O-Rings: EPR.
• Housing Material: Polypropylene (standard) or 316 stainless steel (optional fitting).
• Process Connections:
• NPT: ¼ in., ½ in., ¾ in., 1 in., 1½ in., and 2 in.
• Sanitary: 1.5" Tri-Grip™ sanitary and 2.0" Tri-Grip™ sanitary fittings (CDCE-90S series).
• Cable: Standard length is 4.6 m (15'). Extensions up to 30 m (100 ft) are supported using three-conductor shielded cable; adding "-100" to the model number provides an extended cable option.

Key Product Differences

The series is divided into two primary families based on fitting style and application:

• CDCE-90 Series (In-Line/Submersible): Models such as CDCE-90-001, CDCE-90-01, CDCE-90-1, CDCE-90-10, and CDCE-90-20 feature NPT fittings. The CDCE-90-10 utilizes a CPVC insulator with a maximum temperature of 95 °C (203 °F), while the CDCE-90-20 uses PEEK® insulation for temperatures up to 150 °C (302 °F).
• CDCE-90S Series (Sanitary): Models such as CDCE-90S-001-S15 and CDCE-90S-001-T15 feature Tri-Grip™ sanitary fittings in 1.5" or 2.0" sizes. These models offer electrode options of either 316 stainless steel (suffix S) or titanium (suffix T).
