E+H Orbisint CPS11 Industrial Analog pH Sensor
CPS11-1BA2GSA
The CPS11 industrial analog pH sensor is a high-performance glass electrode designed for continuous, high-precision pH measurement across challenging water treatment and chemical process applications. Featuring a wide measuring range from pH 0 to 14, an advanced dirt-repellent PTFE ring diaphragm, and a double-junction reference system, it effectively resists organic fouling, clogging, and toxic poisoning to deliver long-lasting operational stability. Built to withstand demanding operating environments, this heavy-duty probe performs reliably under continuous working pressures up to 16 bar (232 psi) and temperatures up to 135°C (274°F). The CPS11 holds international ATEX, FM, and CSA explosion-proof certifications, making it an ideal choice for both standard and hazardous industrial processes.
The CPS11 analog pH sensor serves as a highly versatile and robust measurement solution specifically engineered to handle continuous online monitoring in process automation and environmental engineering. Constructed with a chemical-resistant process glass shaft and a large-surface PTFE ring diaphragm, this heavy-duty electrode provides superior measurement accuracy and rapid response times even when exposed to aggressive chemicals, highly alkaline media, or severe process fluctuations. Its advanced gel electrolyte formulation combined with a long poison diffusion path significantly minimizes junction contamination and sensor drift, resulting in extended maintenance intervals, reduced recalibration frequency, and a lower total cost of ownership throughout its long operational lifespan.
Designed for seamless integration into reaction vessels, process pipelines, and water treatment systems, the CPS11 delivers uninterrupted reliability under demanding physical conditions, supporting process pressures up to 16 bar (232 psi) and process temperatures reaching 135°C (274°F). The electrode is available with optional built-in temperature sensors to ensure accurate temperature compensation in real time, while its rugged housing meets IP68/NEMA 6P ingress protection standards. Certified for hazardous area operations worldwide, the CPS11 offers exceptional versatility and peace of mind for demanding industrial applications ranging from chemical manufacturing and pulp processing to municipal wastewater management and power plant water monitoring.
FAQ
Q1: What makes the CPS11 pH sensor suitable for alkaline or harsh media?
A: The CPS11 utilizes a specialized high-alkali glass membrane paired with an advanced gel electrolyte and a large-surface PTFE ring diaphragm. This combination prevents ion poisoning and reduces clogging, ensuring precise pH measurement even in pH > 12 solutions.
Q2: Does the CPS11 include integrated temperature compensation?
A: Yes, the sensor can be ordered with an integrated Pt100 or Pt1000 temperature element built into the glass shaft, allowing your transmitter to perform real-time Automatic Temperature Compensation (ATC).
Q3: Can this sensor be used in explosion-proof / hazardous areas?
A: Absolutely. The CPS11 carries international hazardous area certifications including ATEX, FM, and CSA (Ex ia IIC T3/T4/T6), making it suitable for Zone 0/1 hazardous chemical process environments.
Q4: How should the CPS11 pH probe be stored and maintained?
A: Keep the sensor glass bulb moist using 3M KCl storage solution inside its protective cap when not in use. Clean the PTFE diaphragm periodically with mild detergent or dilute acid (depending on process fouling) to clear surface deposits.
