High yields and high quality product is achieved in fermentation applications with accurate and reliable pH measurement over a narrow range. The CPS171D pH probe has been developed with a unique reference gel and glass membrane. When combined these new features improve the long-term stability for reliable and accurate measurement, even after multiple clean-in place (CIP) and sterilize-in-place (SIP) cycles. The sensor performs well after autoclaving at 284 °F (140 °C). These sensor characteristics, pressurized reference and ion trap make the CPS171D uniquely designed for biotechnology applications.
The Memosens CPS171D provides maximum process safety and data security because of noncontact, inductive digital signal transmission to its cable for communication to the Liquiline transmitter. The inductive connection eliminates problems with measured values being distorted from moisture, and terminals becoming coated or corroded in service.
Memosens technology allows the sensor to store measuring and operating data in the sensor including serial number, calibration date, number of calibrations, offsets, pH application range, number of calibrations, hours of operation under extreme conditions and other information. Recording sensor data in the sensor itself enables predictive maintenance and makes it easy for asset management software, such as Memobase Plus, to facilitate life-cycle management.
Memosens technology also simplifies replacement in the field, because the sensor can simply be replaced with another calibrated sensor, which will automatically transfer its data to the transmitter. Once the sensor has been connected, its calibration is used for the measured value. Calibration data is stored in the sensor, so the sensor can be calibrated and adjusted independently of the measuring point.
