5. Electrical connection
Different variants of the Evaluation unit are available for the evaluation of the sensor signals.
The
MSE 300-FH
variants are supplied in an IP65 housing and can be installed in a free environment
according to the specification.
The
MSE 300-DR
variants are designed for installation in an electrical cabinet. The
MSE 300-DR2
is a
variant of the MSE 300-DR and can be extended to a display as required.
Only the standard variants of all Evaluation units are described below. The Evaluation unit can be installed
at a maximum distance of 300 m from the sensor. A cable of type “Ölflex Classic 110 CY” is recommended.
The cable should be four wired, twisted and shielded. A minimum cable cross-section of 0.75 mm
2
should
be observed. For distances more than 150 m the cable cross-section should be adjusted.
