الوصف
The Yokogawa TB820D is a digital turbidity detector for use with the FLXA402T analyzer. Its right-angle scattered-light measurement, LED source, flat-window cell and diagnostic functions are designed for continuous water-treatment turbidity monitoring.
Verified technical overview
| Measurement method | Right-angle scattered-light method |
|---|---|
| Published ranges | 0–0.2 to 0–500 NTU with 660 nm source; 0–0.2 to 0–700 FNU with 860 nm source |
| Sample temperature | 0 to 50 °C |
| Sample flow / pressure | 0.05 to 20 L/min; 500 kPa maximum |
| System communication | Digital connection to FLXA402T; Yokogawa lists Modbus TCP/IP and Modbus RTU at system level |
Engineering selection checklist
Choose the light-source version and range for the applicable turbidity standard, then define sample conditioning, head tank, cleaning method, calibration arrangement, cable length and installation environment. Confirm the detector and FLXA402T order codes as one measurement system.
| Process data | Measurement objective, normal/minimum/maximum value, medium chemistry, temperature and pressure |
|---|---|
| التثبيت | Sample or immersion arrangement, connection, cable distance, cleaning and maintenance access |
| System interface | Compatible analyzer or host, power, output, communication and alarm requirements |
| Documentation | Confirm the current Yokogawa general specification and complete order code before purchase |
Industry application guidance
Suitable applications include treated-water, river-water, wastewater and general-process-water turbidity monitoring. The sample system must control bubbles, solids loading, flow and pressure so that the published detector performance can be achieved.
