Introduction: The ZDG-728A turbidity online analyzer is a new generation product developed by our company based on the needs of domestic users, drawing on the advantages of similar instruments at home and abroad, and adopting foreign advanced technology. The instrument has beautiful appearance, simple structure, convenient operation, clear display, strong function, good stability and high reliability. The turbidity sensor is based on the combined infrared absorption and scattered light method. The infrared light emitted by the light source is scattered by the turbidity in the sample, and finally converted into an electrical signal by a photodetector, and the turbidity value of the sample is obtained after analog and digital signal processing. It is widely used in the online monitoring of turbidity in water inlets, sedimentation tanks and other links of waterworks; online monitoring of turbidity in sewage plants, various industrial production processes and wastewater treatment processes. Features: The sensor adopts dual-beam infrared scattering photometer detection technology, which has good repeatability and stability; Application of ISO7027 standard method (infrared light scattering technology) can eliminate the influence of sample color; Built-in self-diagnosis function to ensure accurate data; Optional cleaning brush automatic cleaning function, greatly reducing the amount of sensor maintenance; Digital sensor, strong anti-interference ability and long transmission distance; Standard digital signal output, which can be integrated and networked with other equipment without a controller; The on-site installation is convenient and quick, and the appropriate installation method can be selected according to the actual site. Technical parameter: Measuring range: Turbidity: 0.01-100 NTU, 0.01-4000 NTU Measurement accuracy: less than ±1% of the measured value, or ±0.1NTU, whichever is greater Pressure range: ≤0.4Mpa Velocity: ≤2.5m/s, 8.2ft/s Calibration: sample calibration, slope calibration Power supply: 220VAC (50/60HZ) Output: 2 channels 4-20mA Relay: Set up two relays, program set response parameters and response values Communication protocol: MODBUS RS485 Storage temperature: 0 to 60°C Working temperature: 5 to 45°C Dimensions: Transmitter: 144×144×148mm (outer dimensions) 139×139mm (opening size) Weight: Sensor: 1.65KG; Transmitter: 1.8KG Protection level: Sensor: IP68/NEMA6P; Transmitter: IP65/NEMA4X Cable length: standard 10 meters cable, can be extended
