WATER LEVEL RADAR SENSOR RL-15 / RL-35

Description

MEASURING PRINCIPLE

The so-called pulse procedure sends a short microwave impulse to the water surface. Afterwards the sensor remains in standby for a short time. Within this time the water reflects the pulses to the integrated evaluation system. The run time of the impulses corresponds directly to the distance to the current surface water level.

Compact design
Independent of environmental influences (e.g. temperature, wind)
Easy integration into existing systems
Vandalism secure design does not attract attention
Interfaces: 4 to 20 mA, SDI-12 is available as an option
