Field of application
Memosens CPS12E is the digital all-round ORP sensor. It measures reliably even in harsh applications or hazardous areas. Designed for low maintenance and a long operating life, the ORP sensor offers you best value for money. Memosens CPS12E features Memosens 2.0 digital technology that provides the perfect basis for predictive maintenance thanks to extended storage of calibration and process data. The plug & play principle of Memosens allows for easy operation and more process uptime.
Long-term monitoring and limit monitoring of processes with stable process conditions:
- Chemical industry
- Pulp & paper industry
- Power plants
- Incineration plants
Water & wastewater treatment:
- Drinking water
- Cooling water
- Well water
- Wastewater treatment plants
With ATEX, IECEx, CSA C/US, NEPSI, Japan, INMETRO approvals for use in hazardous areas, zones 0, 1 and 2.
Benefits
Robust, low maintenance ORP sensor: Large, dirt-repellent PTFE junction protects from soiling by the medium. Long poison diffusion path prevents poisoning of the electrode reference.
Suitable for harsh applications: Gold pin or platinum cap cover the full range of oxidizing or reducing media. Shaft glass ensures high chemical stability. The sensor is pressure stable up to 17 bar (246.5 psi) absolute.
Memosens 2.0 technology enables the sensor to store more process and calibration data. It lays the basis for IIoT services and predictive maintenance.
-
Extremely reliable measurement with to non-contact, inductive signal transmission results in increased process safety.
Lab calibration and fast sensor replacement on site allow for minimized process downtimes, reducing operating costs.
