일반적으로 정수장 운전 및 제어에 사용된 탁도계는 오늘날 다양한 종류의 산업 폐수에 부유된 물질을 측정하고 화학공정의 혼탁도를 검출하는 것이 요구되고 있습니다.
1959년, Yokogawa가 판매를 시작한 이후 용수 공급 시장을 중심으로 한 탁도 분석계는 많은 판매량으로 여러 유저에게 높은 신뢰성을 제공하고 있습니다.
표면산란광 탁도분석계 TB400G는 고급 기능과 높은 신뢰성을 위한 인텔리전트 성능을 제공하는 마이크로 프로세서를 가지고 있습니다.
Details
- Equipped with a microprocessor, allowing provision of advanced performance and high reliability.
- Enhanced self-testing functions such as detection of a disconnected lamp, a converter check, and upper and lower limit alarms.
- Provided with multiple functions such as automatic zero calibration.
- Compact and lightweight. The system allows access from the front, offering easy maintenance.
- Use of the surface scattering-light measuring method eliminates the measurement errors caused by contamination of the cell port.
- Signal smoothing as a measure against air bubbles in water samples.
Applications
- Turbidity of tap water, sewage, river water and water used in general processes.
| Measuring method | Surface scattering light measurement |
| Measuring range | 0-2 to 0-2000 mg/l |
| Display units | mg/l (standard) or degrees (selectable) |
| Output range | Manual selection from 3 ranges at converter or by remote range switch. Auto-range selection from 3ranges with configurable switching points. The three ranges can be set in any size within the measuring range. |
| Analog output | 4 to 20 mA DC (Maximum load resistance: 550 Ω) or 1 to 5 V DC (output resistance: 100 Ω or less) |
| Digital output signals | RS-232C |
| Contact output | Maintenance output, Failure output, Range output, Configurable contact pair for (a) high and low alarm limits or (b) auto-calibration signal or (c) auto-cleaning signal. |
| Contact input | Remote range switching |
| Automatic cleaning | Water jet cleaning (with configurable time cycles) |
| Calibration | Zero/Span, Automatic or Manual calibration |
| Ambient temperature | -5 to 50℃ |
| Ambient humidity | 5 to 95 % RH (non-condensing) |
| Installation | Indoors (measures to provide waterproofing are optionally required for outdoor installation.) |
| Sample water condition | Flow rate: 1.5 to 2 l/min Temperature: 0 to 50℃ (however, the ambient temperature must be no higher than +30℃) |
| Power supply | 100/110 V AC, 50/60 Hz or 200/220 V AC, 50/60 Hz |
| Linearity (using Kaolin) | When the upper limit of span is 1000 mg/l or less: ±2 % of the upper limit of span |
| Repeatability | 2 % of the upper limit of span |
| Response Time | 2 minutes or less (90 % response, with a sampling system, flow rate of 3 l/min) |
