Field of application
Memosens CPS71E is specially designed for demanding processes. Its unique, contamination-resistant reference and its resistance to moisture ensure reliable measurement even in heavily polluted, aggressive media such as strong acids and bases. Thanks to Memosens 2.0 digital technology, CPS71E offers extended storage of calibration and process data providing the perfect basis for predictive maintenance. Pre-calibration in the lab and quick sensor exchange on site maximize process uptime.
Processes in chemical industry and monitoring of processes with:
High proportion of electrode poisons such as H2S
Quickly changing pH values
With ATEX, IECEx, CSA C/US, NEPSI, Japan, INMETRO approvals for use in hazardous areas, zones 0, 1 and 2.
Benefits
-
The electrode's unique ion trap prevents poisoning of the junction and reference, making it resistant to strong acids and bases and ensuring a long sensor lifetime.
-
The optional pressurized reference allows for reliable measurement in blocking media such as dispersions.
Flexible installation thanks to optional upside-down mounting
-
Inductive cable connection and non-contact signal transmission eliminate any problems due to moisture or corrosion and increase process integrity.
Fast sensor exchange on site reduces process downtime and operating costs.
Memosens 2.0 digital technology makes trend identification and predictive maintenance possible thanks to its extended storage of calibration and process data. The technology paves the way for advanced IIoT services.
