Description
Application
The Memosens CPS71E is designed for challenging processes, offering reliable measurements even in harsh environments. Its unique contamination-resistant reference system and moisture resistance make it ideal for use in aggressive media, such as strong acids and bases. With Memosens 2.0 digital technology, the sensor can store extensive calibration and process data, enabling effective predictive maintenance. The ability to pre-calibrate the sensor in the lab and perform quick on-site exchanges helps to maximize process uptime. It is particularly suited for applications in the chemical industry, including monitoring processes that involve:
- High concentrations of electrode poisons like Hâ‚‚S.
- Rapidly changing pH levels.
The sensor is certified for use in hazardous areas with ATEX, IECEx, CSA C/US, NEPSI, Japan, and INMETRO approvals, suitable for zones 0, 1, and 2.
Benefits
- The electrode's innovative ion trap protects the junction and reference from contamination, making it highly resistant to strong acids and bases, which extends the sensor’s lifespan.
- An optional pressurized reference ensures accurate measurement in challenging media like dispersions.
- Versatile installation options, including upside-down mounting.
- The inductive cable connection and non-contact signal transmission eliminate issues with moisture or corrosion, enhancing process reliability.
- Quick sensor replacement on-site reduces downtime and minimizes operating costs.
- Memosens 2.0 digital technology facilitates trend analysis and predictive maintenance through enhanced storage of calibration and process data, supporting advanced IIoT services.
