Industrial online acid-base concentration electrode PEEK

1、 Core performance: precise anti-interference, capable of handling multiple scenarios

• Parameter accuracy: The measurement range covers 0.5-2000mS/cm, with an accuracy of ± 2% reading or ± 1mS/cm (whichever is greater), and a resolution of 0.01mS/cm to ensure reliable data; Equipped with a built-in Pt1000 temperature sensor, the temperature measurement accuracy is ± 0.5 ℃, which can automatically compensate for the influence of environmental temperature on measurement. The integrated system is suitable for working conditions of 0-80 ℃, and the split system supports a wide temperature range of -30-150 ℃, suitable for complex water bodies with high and low temperatures.

• Durable protection: The integrated shell is made of PEEK/PFA material, and the split type can choose corrosion-resistant SS316L, which can withstand corrosive water bodies such as acid and alkali; Protection level IP68, integrated maximum pressure resistance of 2.1MPa, split type up to 2.1MPa, can be immersed in sewage and chemical solutions for a long time; The longest output cable can reach 500 meters, supporting remote setting and calibration, reducing on-site operating costs.

• Stable Communication: Adopting Modbus RTU communication protocol, default baud rate of 9600, device address of 24, seamless integration with PLC and data acquisition platform, real-time transmission of conductivity, resistivity, etc TDS、 Salinity and other data meet the requirements of intelligent monitoring and centralized management.

2、 Flexible installation: 7 ways to adapt to all scenarios

• Flange type: Suitable for DN65 and above pipelines/storage tanks, the liquid receiving flange can be made of 316L/PVDF material, sealed with an O-ring to ensure no leakage;

• Sleeve type: equipped with NPT2 "liner, used for G2" and above threaded pipelines, installation does not require damage to the original pipeline;

• Clamp type: quick connect flange design, fast disassembly and assembly speed, suitable for DN75 low-pressure pipelines, suitable for scenarios that require frequent maintenance;

• There are also flow cup installation (for low-pressure pipelines), plug-in flange installation (for tank monitoring), submerged installation (for open containers), and pipeline tee flange installation (for low-pressure pipelines). During installation, it is only necessary to ensure that the sensor measurement hole is parallel to the liquid flow path and the pipeline is filled with liquid to ensure accurate measurement.

3、 Calibration and maintenance: low threshold operation, reducing operation and maintenance pressure

• Convenient Calibration: Supports two calibration modes - standard solution calibration (adapted to 1413 μ S/cm, 12.88mS/cm standard solution, completed through register writing instructions), and five point calibration (calibrated in sequence from low to high concentration, at least 2 points are required, and the calibration result is fed back through register 4, returning "8" indicates success), without the need for professional technicians, and can be quickly completed on site.

• Daily maintenance: Disassembly and assembly require SW20 (fixed sensor) and SW32 (tightening lock nut) wrenches, with a maximum torque not exceeding 20N · m, to avoid component damage; Cables need to be isolated from strong electrical lines to prevent signal interference; The parts above the G3/4 threaded mouth should be isolated from the liquid to avoid leakage and damage to the internal circuit; Minor data drift within 5-15 minutes after power failure and restart is a normal phenomenon and does not require repeated calibration.
