Industrial RS485 Water Quality Calcium Ion Sensor
The ZW-CA-PR integrated online calcium ion sensor is a high-performance detection device designed for accurate and reliable online measurement of calcium ion content in water bodies. Based on advanced PVC membrane calcium ion selective electrode technology, it integrates multiple practical functions to meet the needs of industrial and environmental water quality monitoring, providing users with efficient, stable and cost-effective testing solutions.
Core Advantages & Key Features
1. High-precision Testing Performance: The sensor adopts a calcium ion selective electrode based on PVC membrane, which can accurately identify and test the calcium ion content in water. Equipped with professional temperature compensation function, it effectively avoids measurement errors caused by temperature changes, ensuring that the testing process is fast, simple, accurate and economical, and can stably output reliable data for a long time.
2. Stable and Durable Reference System: It is equipped with a patented calcium ion electrode, and the internal reference liquid seeps out from the microporous salt bridge extremely slowly under a pressure of at least 100KPa (1Bar). This special reference system greatly improves the stability of the sensor, and its electrode service life is significantly longer than that of ordinary industrial electrodes, reducing the frequency of maintenance and replacement and lowering the user's use cost.
3. Convenient Connection and Installation: The sensor adopts RS-485 bus and Modbus/RTU communication protocol, which can be easily connected to various third-party equipment such as PLC, DCS, industrial control computer, general controller, paperless recorder or touch screen, realizing seamless integration with the existing monitoring system. At the same time, it is designed with 3/4NPT pipe thread, which is convenient for inserting or installing in pipes and tanks, adapting to different installation scenarios.
4. Strong Environmental Adaptability: With IP68 protection level, the sensor has excellent waterproof and dustproof performance, which can work stably in harsh industrial or outdoor environments, avoiding damage caused by water immersion, dust and other factors, and ensuring the continuity and reliability of online detection.
In summary, the ZW-CA-PR integrated online calcium ion sensor combines high precision, stability, convenience and durability. It is widely applicable to online detection of calcium ion content in industrial wastewater, surface water, drinking water and other water bodies. This user manual will further detail its technical parameters, usage methods, maintenance precautions and communication protocols to help users give full play to the performance of the sensor and achieve efficient and accurate water quality monitoring.
