AL4040/AL4041 On-line Conductivity Sensor

Based on a four - electrode conductivity cell made of graphite, platinum, and stainless - steel materials, it can measure conductivity, salinity, and TDS simultaneously. Conductivity temperature correction is carried out within a wide temperature range. AC pulse drive is used to eliminate the influence of electrode polarization and capacitance effects, which has the advantages of high accuracy, low drift, and low usage cost. The two - electrode AL4040 sensor is easy to maintain and has high accuracy. The four - electrode AL4040 has the advantages of good linearity, wide measurement range, and high accuracy. The shell is made of corrosion - resistant stainless - steel material, and the waterproof level is IP68. It is suitable for on - line conductivity measurement in industries such as surface water, water treatment, aquaculture, boiler return water, deionization process, reverse osmosis, seawater, and aquaculture.

It has an RS485 communication interface and a standard MODBUS protocol, which is convenient for integration and networking. The WQS - SUTIE upper - computer debugging software is provided, which can perform functions such as parameter setting, calibration, measurement, and fault diagnosis of the product.

Two-electrode/four-electrode sensors are optional to meet various measurement requirements.

The electrodes are driven by AC pulses to eliminate electrode polarization and capacitive effects.

Boxcar signal processing technology is used to lower the detection limit and improve data stability.

It has a built-in fault self-diagnosis function to ensure accurate data.

Factory pre-calibration is carried out, and calibration coefficients are built-in. Factory calibration parameters can be restored at any time.

The electrodes are convenient to clean and maintain.

The sensor interface has protection functions against wrong connection and reverse connection.
