Sensorex FCL Series free chlorine sensors

Sensorex’s FCL Series chlorine sensors use amperometric measurement technology to provide accurate monitoring of free chlorine in process applications. The sensors are suitable for use in drinking water disinfection and distribution applications, and are compliant with EPA method 334.0 for measuring drinking water. They are also suited to providing free chlorine monitoring in cooling tower water, an important application for industrial water treatment system providers.

With three models available covering the 0-2, 0-5 and 0-10 ppm ranges, the series meets a broad range of performance requirements. Its membrane design features a mesh reinforcement clamp for increased stability and added durability. The integral 4-20 mA isolated signal output is enhanced to eliminate ground loop errors, reduce noise and block high-voltage transient surges.

For real-time free chlorine monitoring, the sensors interface directly with PLC, SCADA and other process control systems via the 4-20 mA output. A large electrolyte reservoir with an easy-to-replace membrane cap and electrolyte solution reduces maintenance intervals and maximises sensor life. A specialised acrylic flow cell is available to provide a controlled flow environment for measurement stability.
