▪

Avoid mechanical stress to the sensors, e.g. bending or touching with sharp objects.

▪

Hold the sensors with plastic tweezers on the side edges only.

Soldering of the sensor

▪

The maximum temperature of the soldering iron of 320 °C may not be exceeded. Maximum heat apply with

the iron must be below 10 seconds at the very end of the connecting wires.

▪

The calibration of the sensors has to been done 5 days after soldering at earliest. This time is needed to provide

a relaxation after the heat induces during the soldering process.

▪

Avoid soldering flux residues, caused by the soldering process, or any other contaminations inside the active

area of the sensor.

▪

Soldering flux residues on the outside of the sensor’s active area are not critical. If the sensor is mounted with

glue we recommend baking the sensor at 80 °C for 1 hour after the gluing process.

Cleaning of the sensor

▪

Any residues can be easily removed with isopropanol at room temperature. Apply of low ultrasonic energy

might improve the cleaning process. The sensor has to be dried after the cleaning process.

▪

The sensor cannot be cleaned mechanically with cotton swabs for instance.

▪

It is possible to clean the sensor with oil free and filtered clean air, e.g. for removing dust particles.
