The Orbisint CPS11D is an all-round electrode for process and environmental engineering. It measures reliably even in highly concentrated alkalis or in hazardous areas. The low-maintenance design and long service life reduce electrode operating costs. With Memosens digital technology, the CPS11D offers maximum process and data integrity combined with simple operation. The electrode is corrosion-resistant and moisture-proof, and supports laboratory calibration and device pre-maintenance.
Benefits:
-
Anti-fouling PTFE annular diaphragm, robust electrode design, long poison diffusion path, low maintenance requirements
-
For harsh conditions: can measure strongly alkaline media, with stable pressure up to 16 bar (232 psi)
-
Optional salt ring for low-conductivity measurement, e.g. boiler feedwater and water for injection
-
Non-contact inductive signal transmission technology greatly increases process safety
-
Stores sensor characteristic parameters for predictive maintenance
-
Reduces process downtime, extends sensor service life and lowers operating costs
Application areas:
-
Long-term monitoring and limit monitoring under stable conditions:
- Chemical industry
- Paper industry
- Power plants (e.g. flue gas scrubbers, boiler feed water)
- Incineration plants -
Water treatment:
- Drinking water
- Cooling water
- Well water
ATEX, FM, CSA approved, suitable for explosion hazardous areas
