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
- WastewaterWater treatment:
- Drinking water
- Cooling water
- Well water
With ATEX and IEC approval for use in hazardous areas.
Benefits
Simultaneous measurement of pH, ORP and rH values (in rH mode) for a better process overview
Additional platinum electrode enables constant monitoring of reference impedance and thus sensor quality
Robust and resistant to poisoning thanks to large PTFE ring diaphragm and reference with ion trap
Suitable for harsh applications: Process glass for highly alkaline media and pressure-stable up to 17 bar (246 psi)
Maximum process safety through non-contact inductive signal transmission
Enables predictive maintenance due to storage of sensor and process-specific data
Reduced operating costs thanks to minimized process downtime and extended sensor lifetime
Videos
-
The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.
-
Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
