E+H CPS12E Digital ORP Redox Sensor
CPS12E-AA7GAA2
The CPS12E is a heavy-duty digital ORP sensor powered by advanced Memosens 2.0 technology, specifically engineered for robust oxidation-reduction potential monitoring in harsh chemical processes and industrial wastewater treatment. Featuring a contactless inductive connection head, a dirt-repellent PTFE ring diaphragm, and a long poisoning diffusion path, it guarantees 100% moisture-proof signal reliability and exceptional service life under extreme pressure and temperature conditions up to 17 bar and 135°C. With integrated memory for predictive diagnostics and global hazardous area certifications including ATEX and IECEx, the CPS12E streamlines maintenance procedures and maximizes process uptime.
The CPS12E digital ORP sensor represents a versatile and durable solution designed to deliver high-precision redox potential measurements across demanding industrial environments. Built upon Memosens 2.0 digital architecture, the sensor digitizes the analog measurement signal directly within the electrode head, completely removing the risks of signal loss, cable corrosion, and electromagnetic interference caused by high humidity or harsh outdoor environments. Its robust construction combines a high-stability glass shaft with an expansive, dirt-repellent PTFE ring diaphragm and a specialized double-gel reference system, effectively shielding the sensor against toxic media contamination such as sulfides, cyanides, and heavy metals.
The sensor is built to withstand rigorous operating conditions, maintaining structural integrity under pressures reaching up to 17 bar absolute and temperature fluctuations from sub-zero conditions up to 135°C. Beyond physical endurance, the CPS12E provides smart predictive maintenance capabilities by internally storing calibration parameters, operational hours, and exposure history to extreme process conditions. This allows operators to perform sensor calibration in comfortable laboratory settings and execute rapid field swaps within seconds, eliminating local recalibration and drastically minimizing plant downtime. Coupled with comprehensive international hazardous area approvals including ATEX, IECEx, and CSA C/US.
FAQ
Q1: How does Memosens 2.0 digital technology benefit my plant operations?
A: Memosens converts the analog measurement into a digital signal inside the sensor head before inductively transferring it to the transmitter. This eliminates signal loss, moisture interference, and cable noise. Furthermore, sensors can be calibrated in the lab and quick-swapped in the field without recalibration at the measurement point.
Q2: Should I choose a Platinum or Gold measuring element for my application?
A: Platinum pins are ideal for standard oxidizing processes (e.g., chlorine disinfection, nitrite oxidation). Gold pins are recommended for strongly reducing media or applications where chemical side reactions with platinum might occur (e.g., cyanide detox in alkaline media).
Q3: Is the CPS12E compatible with hazardous areas (Ex-zones)?
A: Yes, the CPS12E holds international Ex-approvals including ATEX, IECEx, CSA, and NEPSI for safe deployment in hazardous areas (Zone 0, Zone 1, and Zone 2).
Q4: Can this sensor be installed directly into pressure pipelines?
A: Yes, the robust glass shaft and sealed double-gel reference system allow direct installation in pressure lines or flow assemblies up to 17 bar (246.5 psi) absolute.
