Working Principle Each channel receives weak signal from pH, conductivity or ORP sensor. High impedance sampling circuit processes raw sensor signal, onboard processor calculates physical value according to sensor characteristic curve. Measured value shows on local display and converts to 4-20mA analog signal. HART protocol transmits digital measurement and diagnostic data to DCS system. The analyzer monitors sensor signal continuously and triggers alarm when sensor failure occurs.
Installation Requirements Install inside dry control cabinet; Sensor cable uses low-noise shielded cable; Keep sensor cable away from power cable; Power supply stable; Cabinet grounding must be reliable.
Precautions for Use Perform regular calibration with standard buffer solution; Keep sensor cable connector clean and dry; Do not apply overvoltage to sensor terminals; Check sensor diagnostic information periodically; Calibration operation should be completed under stable ambient temperature.
