SZ616-B&SZ516-CWater Monitoring
Oil-in-Water Sensor
The oil-in-water sensor measures dissolved and emulsified oil using ultraviolet fluorescence, with a range of 0–50 ppm (optional 0–150 ppm), 0.01 ppm resolution, and RS-485 Modbus output. It is suitable for oil field monitoring, industrial circulating water, condensate water, wastewater treatment, and surface water stations. Self-cleaning wiper versions reduce oil contamination and are unaffected by suspended particles in water.
- Measuring range
- 0–50 ppm (optional 0–150 ppm)
- Output
- RS-485, MODBUS protocol
- Operating temperature
- 0–50 ℃
- Power supply
- 0.2 W (non wiping), 0.6 W (wiping); suggested DC 9–24 V, >50 mA (standard) / DC 5–12 V, >500 mA (self-cleaning)
- RS-485 output, Modbus protocol compatible
- Automatic cleaning wiper eliminates oil influence on measurement
- Reduces contamination and is not affected by external light interference
- Not affected by suspended particles in water
- Ultraviolet fluorescence technique with high sensitivity
