RS 485 Network Hart Protocol Modbus protocol No moving parts 1 2 DESCRIPTION The Claritek SM8830 Turbidity Transmitter has been designed for use in industrial applications to measure suspended solids in aqueous mediums Laser light is passed via an optical fiber through the liquid under test Another fiber directly opposite picks up the received light and conducts it to a detector Both laser and detector are housed in a liquid tight junction box and only the optical fibers are in contact with the liquid for increased reliability The measured light is converted to a frequency coded signal for transmission to the SM8830 Transmitter The relationship between the measured light and the suspended solids concentration is mathematically predictable over the measurement range of the instrument The coherent laser light beam maximizes the predictability as compared to incoherent light sources such as tungsten lamps and LED s The Sensor assembly may also contain an optional lens flushing system Clean water is directed across the face of the source and detector windows in a cleaning action The jets are directed downstream to minimize measurement inaccuracy caused by dilution of the liquid medium A 20 character by 4 line LCD and 16 key membrane keypad offer detailed data displays plus ease of calibration and setup In addition a bar graph gives a quick indication of suspended solids concentration Figure 1 0 SENSOR ASSEMBLY 115VAC
