Model: HD2013 | Make: Delta Ohm |
Category: Precipitation Sensor
The HD2013 is a reliable and sturdy tipping bucket rain gauge, built entirely from corrosion-resistant materials in order to guarantee reliability, accuracy, and durability. and to withstand even extreme conditions. Depending on the environment where the rain gauge is placed, there is a choice between a heated and non-heated version (HD2013R).
The principle of a tipping bucket rain gauge is simple: depending on the quantity of rainfall, the tipping bucket mechanism fills and empties. Every tipping action operates a reed contact, thus counting the quantity of rainfall. This means that the tipping bucket has one enormous advantage: it needs no power supply to operate. A power supply is only a necessity when circumstances demand heating because of low environmental temperatures.
The rain gauge is supplied already calibrated and the calibration value (resolution) is shown on the instrument label.
If the amount of rain is calculated using the correction curve as a function of the rainfall rate, the error is typically less than ± 2% in the interval 0…200 mm/h.
If the HD2013-DB data logger is used, the measurement can be automatically corrected according to to the graphs available in the instrument’s operating manual.
With the analog and SDI-12 output options, the curve can be stored in the rain gauge itself.
Reading the number of counts, or in other words, reading the rainfall can be done locally by using a local (battery-operated) datalogger such as the HD2013-DB. However, the results can also be communicated directly via one of our HD33 series data loggers. The built-in 4G/3G/GPRS modem makes it easy to upload the data directly to one of our cloud applications or to your own secured server.
HD2013 is available as well with optional analog output at a choice between 4…20 mA or 0…10 Vdc (to be specified when placing the order) or with optional SDI-12 digital output. When you order, the rain gauge is fully assembled and ready to use. Easy to install, with adjustable feet and a leveling device integrated. Bird spikes and accessories for raised mounting are available.
