Memosens CPS16E features Memosens 2.0 digital technology, offering extended data storage for predictive maintenance. The pH/ORP sensor resists moisture and enables lab calibration which makes the operator's daily tasks easier and maximizes process integrity.
Long-term monitoring or limit control in processes with stable process conditions:
- Chemical processes
- Pulp and paper industry
- Power stations (e.g. flue gas cleaning)
- Incinerator plants
- Mining
- Wastewater
Water treatment:
- Drinking water
- Cooling water
- Well water
With ATEX, IECEx, CSA C/US, NEPSI, Japan, INMETRO approvals for use in hazardous areas, zones 0, 1 and 2.
Benefits
Memosens 2.0 offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services.
The additional platinum electrode enables constant monitoring of reference impedance and is a reliable indicator of the sensor quality.
Simultaneous measurement of pH, ORP and rH values (in rH mode) offers a better process overview and allows for a tighter process control.
Robust: Large PTFE ring junction and reference with ion trap prevent poisoning of the sensor.
Suitable for harsh applications: Process glass for highly alkaline media and pressure-stable up to 17 bar (246 psi).
Reduced operating costs: Lab calibration and fast sensor exchange on site minimize process downtime. Sensor regeneration in the laboratory extends the sensor lifetime.
Non-contact, digital signal transmission ensures reliable measurements resulting in maximum process safety.
