3.3 Memosens technology
Sensors with Memosens protocol have an integrated electronics unit that stores calibration
data and other information. Once the sensor has been connected, the sensor data are
transferred automatically to the transmitter and used to calculate the measured value.
‣
Call up the sensor data via the corresponding DIAG menu.
Digital sensors can store measuring system data in the sensor. These 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 or adjustment
• Operating data
• Temperature application range
• Date of initial commissioning
• Hours of operation under extreme conditions
3.4 Fluorescence cap
The oxygen dissolved in the medium is diffused to the fluorescence layer of the
fluorescence cap. A suitable flow is not required, as no oxygen is consumed during
measurement. However, flow improves the speed at which the measuring system reacts
and ensures a more representative measured value compared to a measurement in a static
medium.
The cap is permeable for dissolved gases only. Other substances dissolved in the liquid
phase, such as ionic substances, will not penetrate through the membrane. Therefore,
medium conductivity has no impact on the measuring signal.
