Rain gauges and rain detectors

Radar rain gauge

WS100 – Radar Rain Gauge

The WS100 is a modern radar rain gauge that uses Doppler radar for non-contact precipitation measurement. Unlike traditional tipping-bucket or weighing rain gauges, it contains no mechanical parts, which significantly reduces maintenance requirements and increases long-term reliability. The sensor measures both instantaneous precipitation intensity and cumulative total and can detect both rain and snowfall. Thanks to its digital output, it is suitable for integration into professional weather stations and telemetry systems.

Rain detector with capacitive output

A rain detector with a capacitive output is used for precise precipitation detection and for converting the information into an analog signal. It provides reliable data for meteorological monitoring, process control, and environmental applications.

RDH11-T – Rain detector with controlled heating and sky temperature sensor

The RDH11-T is an enhanced version of the RDH11 detector that, in addition to detecting rain and snowfall, also measures sky temperature. The device uses a capacitive ceramic sensor for reliable precipitation identification and simultaneously provides information important for advanced meteorological applications (e.g., icing risk assessment or cloud monitoring). The binary output signals the presence of precipitation, while the RS485 interface can be used to transmit approximate precipitation intensity (0–100%), sensor temperature, and sky temperature.

RDH11 – Rain Sensor with Controlled Heating

The RDH11 detector is designed to detect rain or snowfall using a durable capacitive ceramic sensor. During precipitation, a binary output is activated, which can control, for example, automated systems (roller shutters, awnings) or be processed by a data logger. Thanks to the RS485 interface, the data logger can also record approximate precipitation intensity (0–100%), the sensor’s surface temperature, and the ambient temperature.

Rain detector with pulse output

A rain detector with a pulse output is used to quickly detect rainfall and generate a signal for remote transmission. It provides reliable data for meteorological monitoring, process control, and environmental applications.

RG-15 – Optical Rain Intensity Detector with Pulse Output

The RG-15 is an optical precipitation detector that measures both rainfall intensity and precipitation total using an infrared optical system with no mechanical moving parts. The principle involves analyzing a light beam passing through an optical lens—each raindrop impact is detected and converted into a pulse that can be connected to data loggers or telemetry stations.

Tipping bucket rain gauges

Paddle rain gauges are used to accurately measure precipitation using the mechanical paddle principle. They provide reliable data for meteorological monitoring, water management applications, and environmental analyses.

SR02 – Paddle Rain Gauge (200 cm²)

The SR02 is a tipping-bucket rain gauge with a collection area of 200 cm² designed to measure the amount of rain and other liquid precipitation using a tipping bucket. Each flip generates a pulse corresponding to 0.2 mm of precipitation. This technology is ideal for connecting to data loggers and telemetry stations for remote monitoring of precipitation and its intensity.

SR03 – Paddle Rain Gauge

The SR03 is a mechanically robust dipper-type rain gauge with a precise collection area of 500 cm² designed to measure both liquid and solid precipitation. Measurements are based on the principle of a split-paddle tipping mechanism, which generates a pulse signal corresponding to the amount of precipitation (0.1 mm/pulse). This pulse output can be easily connected to data loggers or telemetry stations for further data processing.
