The TS7 Sensor is a measuring system best suited to continuously and consistently measure the Turbidity and the concentration of Suspended Solid in drinking water, surface water, ground water, sewage or industrial wastewater treatment facilities.
The sensor uses a measuring method that compares transmitted light with scattered light. The sensor is designed with due care to the arrangement of the optical system. These design makes the sensor less susceptible to disturbing light. The cleaning wiper unit permits continuous and consistent measurement even in an application where the sensor is exposed to contaminants.
The TS7 Sensor is composed of a light source and a light detector (photodetector). When the incident light is scattered by the particles in the sample, the detector collects the scattered light. The amount of scattering measured by the sensor is mainly determined by the concentration of particles in the sample, the size and physical characteristics of the particles, and the wavelength of the emitted light used. The light source of the sensor adopts a near-infrared LED (880nm), and the 90°scattered light method is used for measurement, which complies with ISO 1027/EN 27027 to ensure accurate measurement of the turbidity value.
In addition, the built-in automatic wiper can keep the surface clean and remove air bubbles that may be attached to the optical measurement window, thereby minimizing unplanned downtime and maintenance, and ensuring the effectiveness of the measurement
