Endress+Hauser Liquiline M CM42 - Operation via the Fieldbus

4
Memosens The measuring point is safer with Memosens:
• No-contact, inductive signal transmission, thus optimum galvanic separation
• No contact corrosion
• Completely water-tight
• Automatic error message if data flow interrupted
• Sensor calibration possible in laboratory
• Look-ahead maintenance thanks to recording of sensor data, e.g.:
– Total hours of operation
– Hours of operation for very high or very low pH values
– Hours of operation for high temperatures above 80 °C (176 °F) and 100 °C (212 °F)
– Number of steam sterilisations
Software packages You can select the software functionality to suit your needs. Consequently, you can avoid a "software overload"
while still having all the required features.
You can choose from the following from these software packages:
• Basic:
Standard application for the most common measuring points
• Advanced:
Highest degree of accuracy (medium compensation) and safety (Cal-Timer) in critical applications
• Advanced Plus:
In addition to the Advanced package, the requirements of the FDA are taken into consideration
