Rosemount Analytical 400-11 Endurance Contacting Conductivity Sensor
The Rosemount Analytical 400-11 Endurance Contacting Conductivity Sensor is engineered for precise measurement of electrolytic conductivity in clean, non-corrosive liquids with conductivity levels up to 20,000 µS/cm. This sensor is particularly suitable for applications such as high-purity water and clean cooling water systems.
Key Features
- Cell Constant: 0.01/cm, ideal for low conductivity measurements ranging from 0.0 to 200 μS/cm.
- Process Connection: ¾ inch MNPT fitting for direct screw-in insertion into process piping.
- Temperature Range: Operates effectively between 32°F and 221°F (0°C to 105°C).
- Pressure Rating: Maximum pressure capacity of 250 psig (1825 kPa abs).
- Construction Materials: Features concentric titanium electrodes separated by a PEEK insulator, with EPDM O-rings ensuring a secure seal against process liquids.
- Calibration: Factory-measured cell constant ensures out-of-the-box accuracy, eliminating the need for initial calibration.
