Technical Information
Orbisint CPS11D and CPS11
pH electrodes, analog or with digital Memosens
technology
For standard applications in process and
environmental technology, with dirt-repellent
PTFE diaphragm, built-in temperature sensor
(optional for analog sensor)
Application
• Long-term monitoring and limit value monitoring of processes with stable process
conditions
– Chemical industry: strong acids/bases, plastic, pulp and paper industry
– Power plants (e.g. flue gas cleaning), oil and gas
– Incinerator plants
• Water/wastewater treatment
– Boiler feedwater and cooling water
– Well water and drinking water
– All industrial and municipal treatment plants
With ATEX, IECEx, FM, CSA, TIIS and NEPSI approval for use in hazardous areas
Your benefits
• Low-maintenance and robust thanks to large PTFE ring junction
• Can be used at pressures up to 17 bar abs. (246 psi)
• Process glass also for very alkaline applications (BA and BT versions)
• Process glass for applications in media containing hydrofluoric acid (FA version)
• For media with low conductivity (AS version)
• Integrated NTC30K temperature sensor (Memosens) for effective temperature
compensation; Pt100 or Pt1000 for analog sensors
• Optional: Poison-resistant reference with ion trap
Other advantages of Memosens technology
• Maximum process safety
• Data security thanks to digital data transmission
• Very easy to use as sensor data saved in the sensor
• Recording of sensor load data in the sensor enables predictive maintenance with
the Memobase Plus CYZ71D
