Tipping bucket rain gauge (catchment area 200 cm²) / HD2015
Senseka (formerly Delta Ohm)
A rain gauge with high measurement accuracy and reliability, and excellent durability.
■ High-resolution measurement is possible. In addition to the standard 0.2mm, specifications can be set for 0.1mm and 0.5mm. ■ The main body is made entirely of corrosion-resistant materials, ensuring excellent long-term reliability. In the heater-equipped version, the heater automatically operates around +4°C to eliminate residual snow and ice even in low environmental temperatures or during/after snowfall. ■ The power supply voltage is DC24V (HD2015R) or DC12V (HD2015R1), with a power consumption of approximately 75W. ■ The measured rainfall is based on the number of times the tipping bucket empties: (1) A collection cone connected to an aluminum cylinder directs rainwater into the tipping bucket. (2) When the specified level is reached, the accurately calibrated tipping bucket rotates under its own weight to drain the rainwater. (3) During the rotation of the bucket, a normally closed reed contact opens momentarily, sending a pulse signal to the counter. * The number of pulse signals is detected and recorded by data loggers or pulse counters such as the HD2013-DB. ▲ Rain, snow, and ice measurements are possible with the heater-equipped models (HD2015R/R1). ▲ Resolution per pulse can be selected as 0.1mm/0.2mm (standard)/0.5mm. ▲ Bird deterrent spikes and wireless loggers for cloud connectivity are also available as options.
