Memosens (CPS471D)
Maximum process safety
The inductive and non-contacting measured value transmission of Memosens guarantees maximum process
safety and offers the following benefits:
• All problems caused by moisture are eliminated.
– The plug-in connection is free from corrosion.
– Measured value distortion from moisture is not possible.
– The plug-in system can even be connected under water.
• The transmitter is galvanically decoupled from the medium. The result: No more need to ask about
"symmetrically high-impedance" or "unsymmetrical" (for pH/ORP measurement) or an impedance
converter.
• EMC safety is guaranteed by screening measures for the digital measured value transmission.
Data safety through digital data transfer
The Memosens technology digitalizes the measured value in the sensor and transfers it to the transmitter via a
contactless connection. The result:
• An automatic error message is generated if the sensor fails or the connection between sensor and transmitter
is interrupted.
• The availability of the measuring point is dramatically increased by immediate error detection.
• The digital signals are suitable for application in hazardous areas; the integrated electronics are intrinsically
safe.
Easy handling
Sensors with Memosens technology have integrated electronics that allow for saving calibration data and
further information such as total hours of operation and operating hours under extreme measuring conditions.
When the sensor is mounted, the calibration data are automatically transferred to the transmitter and used to
calculate the current measured value. Storing the calibration data in the sensor allows for calibration and
adjustment away from the measuring point. The result:
• Sensors can be calibrated unter optimum external conditions in the measuring lab. Wind and weather do
neither affect the calibration quality nor the operator.
• The measuring point availability is dramatically increased by the quick and easy replacement of precalibrated
sensors.
• The transmitter does not need to be installed close to the measuring point but can be placed in the control
room.
• Maintenance intervals can be defined based on all stored sensor load and calibration data and predictive
maintenance is possible.
• The sensor history can be documented on external data carriers and evaluation programs at any time. Thus,
the current application of the sensors can be made to depend on their previous history.
Communication with the transmitter
Always connect digital sensors with Memosens technology to a transmitter with Memosens technology. Data
transmission to a transmitter for analog sensors is not possible.
The sensor is connected to the cable connection (CYK10) without contact. The power and data are transferred
inductively
Once connected to the transmitter, the data saved in the sensor are read digitally. You can call up these data
using the corresponding DIAG menu.
Data that digital sensors save include the following:
• Manufacturer data
– Serial number
– Order code
– Date of manufacture
• Calibration data
– Calibration date
– Calibration values
– Number of calibrations
– Serial number of the transmitter used to perform the last calibration
• Operational data
– Date of commissioning
– Hours of operation under extreme conditions
– Number of sterilizations
– Data for sensor monitoring.
