Overview
Novo ZS-600 (submerged) online Turbidity Meter is used to measure the degree of obstruction of suspended solids in water to the transmission of rays of light, and can detect turbidity caused by soil, dust, microorganisms, etc. Sensor calculates turbidity by emitting light waves, measuring transmitted light and scattered light intensity, using RS485 interface communication, accurate data and strong anti-interference, support calibration and automatic cleaning functions.
Features
1. Large screen dot matrix LCD display, support Chinese and English menu switching
2. Built-in bubble elimination system (flow type), improve Measurement accuracy and Stability
3. Good reproducibility, not affected by sample flow rate and pressure (input type)
4. Infrared source, avoid chroma and external light interference, built-in luminosity compensation
5. With water storage function (circulation type), ensure that the internal circulation tank retains water samples for 24 hours
6. Adopt new detection technology (submerged), with strong resistance to external light interference
7. The light path uses high light transmitance quartz Glass lens, and the infrared light wave emission and reception are stable
8. Optional RS-485 communication interface (MODBUS protocol partially compatible), 4-20mA current output can be arbitrarily set
9. Photoelectric isolation 4-20mA current output
10. The hysteresis can be set arbitrarily to avoid frequent operation of the relay, and the switch can be set to turn off and close
11. Adopt multi-point correction method
12. Automatic cleaning interval can be set freely (Sensor support is required)
13. Watch dog function to ensure that the meter does not crash
14. Core components come from foreign brands
15. Power failure protection > 10 years
Principle
The Sensor emitter transmits light waves, which are absorbed, reflected and scattered by the measured object during transmission. Part of the transmitted light is irradiated to the 180 ° Direction Detector, and part of the scattered light is irradiated to the 90 ° Direction Detector. The turbidity value is calculated by measuring the intensity of the transmitted and scattered light, combined with its relationship with the sewage turbidity. The product uses the RS485 interface to communicate with the digital Sensor to achieve High Accuracy data collection.
Applications
Wastewater treatment, water quality monitoring, industrial process control, environment monitoring
Standards
MODBUS protocol partially compatible
Steps
1. Connect power supply and working environment
2. Communicate with Sensor via RS485 interface
3. Use Chinese and English menus to set parameters
Step 4 Perform multi-point calibration
5. Set the automatic cleaning interval (e.g. Sensor support)
6. Start measurement and monitor data output
Notice
• Ensure that the environment temperature is 0~ 60 ℃, relative humidity ≤ 90%
• The output load must meet the requirements: load < 500Ω (0-10mA), load < 750Ω (4-20mA)
• Relay load does not exceed 3A 220VAC/24VDC
• Sensor support for automatic cleaning function
• The protection level is IP65 (meter) and IP68 (Sensor), pay attention to the matching of the installation environment
