242 Flow Through Toroidal Conductivity Sensor
Brand: RosemountRosemount 242 toroidal conductivity sensors feature noninvasive flow through design allowing for in-line installations without any obstruction to sample flow.
These sensors are ideal for measuring conductivity in highly conductive liquids up to 2 S/cm (2,000,000 μS/cm) and for use in viscous, abrasive, or fibrous liquids.
Features- Robust measurements - insensitive to process flow rate and direction
- Plugging resistant and suitable for liquids containing high levels of suspended solids
- Avoid accumulation of solids with no part of the sensor protruding into the sample flow
- Minimize down time with in-line calibrations
- Line sizes of 1, 1.5, 2, 3, and 4 inches (25, 40, 50, 80 and 100 mm) are available with ANSI and DIN compatible flanges
- Ensure process compatibility with a variety of liner and O-ring materials
- Simplified wiring with integral junction box
