Core Highlights
- The variable temperature compensation method supports PT1000, NTC10K, and manual temperature compensation, responds to industrial site temperatures, and ensures corrosion rate accuracy.
- Isolation technology prevents industrial electromagnetic interference and stabilizes data flow in the 4-20mA output.
- Intelligent relay control: Allowing the three sets of relays’ high and low points to be freely swapped and automatically adjusting the hysteresis minimizes repeated relay on-off and prolongs equipment life.
- By eliminating the need to physically disassemble and clean electrodes, automatic electrode cleaning device contacts save operating and maintenance costs.
Featured Applications
- Metal parts like heat exchangers, condensers, and pipes used in boiler feedwater and cooling water systems at power plants are checked for rust.
- Keeping an eye on how the water systems in refineries, chemical plants, and pipelines carrying crude oil rust in the petrochemical business.
- Acid washing, corrosion inspection, cooling circulating water systems, and steel and non-ferrous metal smelting plants are all part of the metallurgical business.
- In the food and drug businesses, keeping an eye on corrosion in metal pipes, tanks for clean water storage, and cooling systems for circulating water.

Daily maintenance and precautions
Installation precautions
- The host should be put in a well-ventilated, dry place away from strong magnets and earthquake sources. It can be put on a disk or the wall.
- At the monitoring point, the electrode has a DN25 tee fitted to make sure it is completely submerged in the medium. The matching electrode is chosen based on the material of the equipment.
- Separate the wiring of the signal, power, and relay circuits and make sure they are properly grounded.The connectors should also be waterproof sealed.
- Connect the electrode to the host by a fixed line so that pulling doesn’t damage them.
Daily maintenance and calibration
- The host only needs to wipe the surface dust with a dry cloth in daily life, regularly check whether the wiring interface is loose, and there is no need to disassemble and maintain it unless there are special circumstances.
- Utilize the built-in electrode of the device to automatically clean the contact points, regularly initiate the cleaning program, and remove dirt and sediment from the electrode surface; If there are many impurities in the on-site medium, the cleaning frequency can be increased.
- Regularly calibrate the electrodes, with the calibration cycle adjusted according to the working conditions of the medium on site. Generally, calibration is done once every 1-3 months to ensure measurement accuracy.
- Daily inspections focus on the corrosion rate, temperature values, and relay status of the instrument panel. If there are abnormal values or frequent alarms, promptly investigate electrode contamination or circuit faults.
- When the equipment is shut down for a long time, turn off the power supply, remove the electrodes and clean them properly, soak them in a special protective solution for storage, and seal the main unit against dust.
