Type 8906 Description DESCRIPTION Area of application The Online Analysis measurement system Type 8906 on backplate is, independantly to its arrangement, dedicated to provide physico-chemical parameters and process values used to check and control the quality of clear water, such as surface water, underground water, drinking water, softened or osmotic water. Defined as a modulable construction, the system Type 8906 can provide different measurements, arrange- ments and communication protocol, selected and adjusted to the expressed requirements. Depending on the arrangement selected, one or more of the following measurements can be proposed: conductivity, OPR, pH, Chlorine or Chlorine dioxide, dissolved iron and/or oxygen, turbidity, Nitrate, UV 254, temperature or flow. System overview The Online Analysis measurement system Type 8906 on backplate is a flexible and tunable solution designed to a specific application. Depending on the selected configuration, the system Type 8906 can contain: • One or several PVC backplates that can be fixed on the wall and that are wired to the water supply to be analyzed. Each backplate can be tuned with specific functions (display, flowmeter, bubble trap, cleaning system…) and can perform specific measurement of the connected fluid. • One or several boxes, fixed on the wall and wired to the power supply. The boxes can be tuned with spe- cific functions (IO-modules, gateway, power supply…). The backplates and boxes have to be wired together. See chapter 5 Installation. 1. Backplate 1 in PCV 2.

Page 10: Measuring Principle
Type 8906 Description Measuring principle The Online Analysis measurement system Type 8906 on backplate is dedicated to the analyze, the acqui- sition and the regulation of clear water (drinking water or industrial water), connected to the installation through different type of sensors. The use of the system with liquids other than water (drinking water or clear industrial water) may damage the sensors or the components of the system, generate the development of bacterium in the pipes or inside the sensors. For using the system with other media than water, please contact the Bürkert Customer Service. Depending on the configuration of the system, different measuring and/or analysis sensors can be pro- posed, each of them having their own measuring principles, assembly constraints and recommendations. 3.3.1 Sensor cubes For measuring and monitoring of characteristics such as conductivity, pH, ORP, Chlorine and/or turbidity, the Online Analysis measurement system Type 8906 on backplate is based on Bürkert’s sensor cube tech- nology, mounted on a backplane which is fixed on the PVC backplates. All sensor cubes have the same dimensions, can be interchanged and can offer different type of measure- ments. The following sensor cubes are available for the system: • a pH and temperature sensor cube • a chlorine and temperature sensor cube • a chlorine dioxide and temperature sensor cube • a conductivity and temperature sensor cube • an ORP (redox potential) sensor cube • a turbidity sensor cube Each sensor cube is identified by a specific logo on its push-button: MS01 MS02 MS03 MS04 MS05 Logo on the... - Page 11 Type 8906 Description When the sensor cube is removed from its backplane, the interface is tight. A locking pin prevents from unintentional move of the bayonet lever. DANGER Risk of injury due to the nature of the fluid if no sensor cube is plugged on a backplane. If the fluid outlet of the backplane is open, fluid may splash on you. • The fluid outlet must stay closed if the backplane has no sensor cube. • Do not move the bayonet lever with the hand. NOTICE The backplane may be damaged if no sensor cube is plugged on a backplane. A short-circuit may damage the backplane if the electrical contacts are touched with a conductive material. ▶ Do not touch the electrical contacts. ▶ Cover the electrical contacts with a correct protection cap: contact the manufacturer.
