Intended Use
The SE 655 toroidal conductivity sensors with Memosens protocol are particularly suited for applications in
the chemical industry and for process engineering. The SE 655 sensor is equipped with Memosens technolo-
gy. This allows an integrated sensor diagnostics as well as the saving of calibration data, operating time, sen-
sor designation and serial number in the sensor. The serial number is also printed in the quality certificate and
on the packaging label.
Using the Memosens protocol for data transmission allows the above mentioned sensor data to be transmit-
ted to the measuring device and to be saved and processed.
Thanks to the large measuring range over six decades and the high chemical resistance of the process-wetted
parts made of PEEK, almost every conceivable application is possible, such as concentration determination of
acids, bases and salt solutions, monitoring of product quality
or phase separation of product mixtures.
Safety Instructions
• Make sure that the sensor is without visible mechanical damage.
Use the sensor for the intended purpose only.
• Hazards due to pressure, temperature, aggressive media or other influences are possible, depending on the
location of use. Therefore, the installation, operation, and servicing of the sensor shall only be carried out
by suitably trained personnel authorized by the operating company.
• Manipulations of the equipment other than described in the user manual are not permitted.
• The sensors have been developed in compliance with the applicable European directives
and standards.
Be sure to follow the instructions given in this user manual for connecting and operating
the SE 655 sensors.
• Observe the specified ranges for ambient temperature and process temperature to ensure safe use of the
sensors.
• Take care to maintain the IP 68 protection when installing the sensor.
(Use original gaskets, insert the cables in a professional manner.)
• Make sure that the gaskets are securely in place. Otherwise, the assembly is not tight.
• Do not dismantle the sensor as long as the process medium is under pressure.
