The Senvolon Level Sensor RD uses 80 GHz RADAR technology, the industry standard for level measurement that has proven itself in process industry applications for years. Since measurement is contactless and has no moving parts, the sensor is robust and low-maintenance. Liquids are measured to the millimeter, up to 40 m deep. Fog, dust, or condensation in the tank do not affect the measurement. MIN/MAX monitoring is built in, and the housing is IP65-protected. It shows all readings directly in your browser, no app or cloud required. In addition, it can be integrated into Home Assistant, ioBroker and other smart home systems via MQTT. Optional cloud services hosted in Germany are available, for example for push notifications on the go.

FAQ
Answers to frequently asked questions.
We grant a three-year warranty on all our products. This covers manufacturing and material defects.
Our level sensors measure without contact, either with light (LiDAR) or with microwaves (RADAR). The choice depends on the accuracy you need, the medium being measured and the conditions in the container:
LiDAR (light)
RADAR (microwave)
You can find the range, accuracy and antenna options of each model in the technical data on the respective product page.
The fill level can be measured in any container geometry, as long as the depth is within the range of the respective model (see technical data). Typical application scenarios include:
