Process sensor assemblies for cleaning and calibration
Endress+Hauser’s Cleanfit CPA875 and CPA871 sensor assemblies allow pH, ORP, oxygen and NIR sensors to be installed or removed during operation so they can be cleaned, calibrated or replaced without interrupting the process. The Cleanfit CPA875 is designed for the pharmaceutical and food and beverage industry. The assembly for the CPA875 has seals, process connections and couplings that are designed for those applications. The CPA871 sensor is ideal for applications in the water and wastewater and chemical industries and has retractable assemblies that permit removal and installation, while protecting both the process and operating personnel.
Both sensor assemblies are available with a manual or an automatic drive. The manual drive has a self-retaining thread to hold the sensor in any intermediate position, and can be used for process pressures up to 116 psi. The pneumatic drive can be used for process pressures up to 232 psi. In assemblies with a pneumatic drive, the service and measuring positions of the sensor are detected and reported to connected monitoring and control systems.
