Endress+Hauser Memosens CCS51D free chlorine sensor

The Memosens CCS51D amperometric sensor from Endress+Hauser measures free chlorine in drinking water, process water, water and wastewater treatment, cooling water and all utilities requiring clean and treated water. The device features a membrane design that provides a fast response time, helping plant operators run their disinfection processes quickly and efficiently, while also saving on chemicals.

The sensor’s convex membrane is made from dense, dirt-repellent material that prevents soiling and makes it resistant to biofouling. Ultrasonic welding of the membrane to the sensor cap ensures its integrity, preventing dilution of the electrolyte and thus a drift of the measuring signal. This guarantees long-term stable measurements and gives water plant managers the security that the disinfection process is running smoothly and that the required disinfection results are achieved.

The device is equipped with Memosens technology, allowing for direct commissioning of new sensors without further calibration. During ongoing operation, plant operators can pre-calibrate sensors in the lab, swap them into the process with plug and play, and thus continue measuring faster. Finally, non-contact data transmission eliminates all measurement errors or failures caused by humidity or corrosion.

Memosens CCS51D is connected to the Liquiline multiparameter transmitter that can serve up to eight sensors simultaneously, and the Flowfit CCA250 flow assembly offers mounting space for a simple installation of the additional pH sensor.
