Smart Data Transmitter
Smart Sensor System
Typical applications including water/wastewater treatment, fish farming, chemical process, environmental water analysis:
1. The user friendly WT100 transmitter provides a large compartment with pre-assembled rear unit for easy wall, pipe and tube, as well as panel mounting for wastewater measurements. The reliable sensor cap offers a stable data output and long life time in these demanding applications.
2. The WT100 transmitter can work with a series of sensors having a 3/4NPT fitting, which provides a fully robust and reliable data analysis for fish farming and other smart agriculture. Customization is also provided including modifications of installation fitting, length and insertion depth, housing materials and other possible adaptation changes.
3. The WT100 transmitter typically comes with a reliable fluorescent dissolved oxygen sensor (optional pH/ORP, Chlorine, Conductivity and Turbidity sensors). The easy-to-operate feature is a choice for environmental water monitoring and analysis in fields.
Temperature Compensation:
The influence of temperature on the sensor signal is manifested in two aspects: first, the mechanism of the kinetic influence of temperature on the dynamic quenching process of fluorescent molecules and oxygen molecules during fluorescence quenching (enhancing or weakening the fluorescence quenching effect); second, the temperature affects the solubility of oxygen (or inorganic salts) in water; the oxygen concentration data detected by the fluorescent oxygen sensor automatically compensates for the impact of the above temperature.
Air Pressure Compensation:
Changes in dissolved oxygen concentration caused by changes in pressure (or altitude) of the sensor in the application environment can be automatically compensated at the sensor or instrument end, or pressure data can be manually entered for compensation.
Salinity Compensation:
Changes in dissolved oxygen concentration caused by changes in salinity (or electrical conductivity) of the sensor in the application environment can be automatically compensated at the sensor or instrument end, or manually enter salinity data to compensate.
Fluorescent Oxygen Sensor Model：
1) Conventional model HF-0101:
a) Dissolved oxygen concentration: 0-25mg/L
b) Dissolved oxygen saturation: 0-250%
c) Operating temperature: 0-55°C
d) Operating pressure: 0-150kPa (0-1.5atm)
e) Storage temperature: -20-80°C
2) Small-range model HF-0102:
a) Dissolved oxygen concentration: 0-2.0mg/L (0-2000ppb)
b) Dissolved oxygen saturation: 0-20%
c) Operating temperature: 0-80°C
d) Operating pressure: 0-450kPa (0-4.5atm)
e) Storage temperature: -20-80°C
3) Large-range model HF-0103:
a) Dissolved oxygen concentration: 0-50mg/L
b) Dissolved oxygen saturation: 0-500%
c) Operating temperature: 0-55°C
d) Operating pressure: 0 -150kPa (0-1.5atm)
e) Storage temperature: -20-80°C
Fluorescence oxygen sensor response time：
1) T-90 (reaching 90% of the final reading) ≤60 s (25°C, the time it takes for the saturation to drop from 100% to 10%)
2) T-95 (reaching the final 95% of reading) ≤90 s (25°C, the time it takes for the saturation to drop from 100% to 5%)
3) T-99 (reaching 99% of the final reading) ≤180 s (25°C, the time it takes for the saturation to drop from 100% to 1%)
