Sensorex CLD500 chlorine dioxide sensors

Sensorex’s CLD500 chlorine dioxide sensors use advanced amperometric measurement technology to provide highly accurate monitoring of chlorine dioxide in disinfection applications. With two models covering the 0-2 ppm and 0-10 ppm full scale ranges, the sensors can be used in new installations or as a field replacement for existing sensors in chlorine dioxide generators and water-treatment systems.

The sensors’ advanced sensing membrane keeps cross sensitivity interference from free chlorine to a minimum. The sensor offers improved sensor stability over the entire operating temperature range. An integral 2-wire loop-powered transmitter with 4-20 mA output delivers readings to process control systems such as a PLC or DCS. The CLD502 covers the 0-2 ppm range, while the CLD510 model covers the 0-10 ppm. A large electrolyte reservoir with an easily replaced membrane cap and solution may reduce maintenance and improve sensor life.
