Product profile: PCH-800 chlorophyll sensor uses the characteristic that chlorophyll A has absorption peak and emission peak in the spectrum. It emits monochromatic light of specific wavelength into water, and chlorophyll A in water absorbs the energy of the monochromatic light. Another wavelength of monochromatic light is released, and the intensity of chlorophyll A emission is proportional to the content of chlorophyll A in water. Product characteristics: It is based on the fluorescence of pigment to measure the target parameters, can be recognized before the potential impact of Shui Hua; No need for extraction or other treatment, rapid detection, to avoid the use of water samples caused by the impact; Digital sensor, strong anti-jamming ability, long transmission distance; Standard digital signal output, can be integrated with other equipment and network without controller; Sensor field installation is convenient and quick to achieve plug-and-play. Technical parameters: Measuring range : 0 - 500 ug / L Measurement accuracy : ± 5 % of the corresponding value of the signal level of the 1 ppb rhodamine WT dye Pressure range : ≤ 0.4Mpa Calibration : Deviation Calibration , Slope Calibration The conditions require that the chlorophyll distribution in the water is very uneven and the multipoint monitoring is recommended ; the turbidity of the water is less than 50 ntu . Sensor main material : Body : SUS316L + PVC ( plain version ) , titanium alloy ( seawater version ) ; O - ring : Viton ; cables : PVC Power supply : AC power supply : 100 - 240VAC ( 50 / 60HZ ) ; DC supply : 9 - 36VDC Output : 3 - Way 4 - 20mA Relay : Set three - way relay , program setting response parameter and response value Communication Protocol : Modbus RS485 Storage temperature : -15 to 65 ℃ Operating temperature : 0 to 45 ℃ Dimensions : transmitter : diameter 37mm * length 220mm ; Transmitter : 145 * 125 * 162mm ( length * width * height ) Weight : sensor : 0.8KG ; Transmitter : 1.35 KG Protection grade : sensor : IP68 / NEMAIL ; Transmitter : 65 ° / NEMA4X Cable length : The cable length is 10 meters , which can be extended to 100 meters .
