E+H Orbipac CPF82 Industrial Analog Sensor Probe
CPF82-PA11A2
Engineered for demanding process liquid monitoring, the Orbipac CPF82 Industrial Analog ORP Sensor provides continuous and high-accuracy redox measurement ranging from -1500 mV to +1500 mV in aggressive industrial water environments. Featuring a rugged PPS body, a dirt-repellent PTFE annular ring diaphragm, and a patented KNO3 double-chamber reference salt bridge, this heavy-duty sensor offers superior protection against severe electrode poisoning caused by sulfides and cyanides, effectively minimizing maintenance downtime in turbid, high-solids wastewater, mining, and chemical neutralization processes.
The Orbipac CPF82 Industrial Analog ORP Sensor is a high-performance, heavy-duty redox electrode specifically engineered for continuous online monitoring in harsh industrial water and process control applications. Constructed with a durable polyphenylene sulfide (PPS) housing and a refined glass sensing element with a platinum pin, the sensor maintains exceptional mechanical robustness and chemical resistance when submerged in aggressive acids, alkalis, and abrasive mineral slurries. Designed with versatile NPT 3/4-inch male threads integrated into both the top and bottom ends of its housing, the CPF82 accommodates flexible mounting configurations including direct inline pipe insertion, immersion in tanks, or installation within flow-through chambers.
At the core of the CPF82 design is its advanced double-chamber reference system featuring a specialized potassium nitrate salt bridge. This secondary barrier prevents severe electrode poisons—such as sulfides, cyanides, and heavy metal ions—from reaching the internal silver/silver chloride reference electrode, effectively preventing premature sensor failure and drastically extending service life in severe industrial applications. Furthermore, the large-surface annular PTFE diaphragm ensures optimal and continuous electrical contact with the process medium, actively resisting bio-fouling, dirt accumulation, and chemical scaling. Whether integrated into industrial wastewater neutralization systems, mining flotation circuits, cyanide oxidation tanks, or heavy-metal precipitation processes, the CPF82 provides uninterrupted signal stability and reliable process control while significantly reducing overall operational costs.
FAQ
Q1: What makes the CPF82 analog ORP sensor ideal for harsh wastewater applications?
A: The CPF82 features a dirt-repellent PTFE diaphragm and a patented $\text{KNO}_3$ double-chamber reference system. This design prevents electrode poisoning from sulfides, cyanides, and heavy metals while avoiding diaphragm clogging caused by suspended solids.
Q2: What process connections are supported for installation?
A: The sensor comes built-in with $NPT\ 3/4”$ threads at both the top and bottom ends. This allows flexible mounting in immersion pipes, flow-through chambers, or directly screwed into process piping.
Q3: What is the difference between an analog ORP sensor (CPF82) and a digital Memosens ORP sensor (CPF82D)?
A: The analog CPF82 transmits raw millivolt ($mV$) signals directly via standard coaxial/TOP68 cables to compatible controllers or transmitters. The digital CPF82D incorporates Memosens technology, storing calibration data directly inside the sensor head and offering contactless inductive signal transmission.
Q4: How often does the CPF82 require calibration and cleaning?
A: Calibration frequency depends on media composition and operating temperature. Thanks to its large PTFE diaphragm and stable gel electrolyte, cleaning intervals are significantly extended compared to traditional glass ORP probes. Routine cleaning with mild acid/detergent solutions is recommended.
Q5: Can you provide OEM branding or custom cable lengths for B2B orders?
A: Yes, as a professional automation instrumentation manufacturer, we provide OEM/ODM customization options including custom thread fittings, integrated temperature sensors, cable length options, and white-label branding for global distributors.
