HD 2015 Precipitation Measurement Transmitter

Technical Description

Device type / operating principle

  • The HD2015 is a rain gauge based on the tipping bucket principle.

  • Rainfall is collected by the cone and directed into the bucket. Once the bucket fills with a preset volume, it tips, empties, and generates an impulse via a reed contact. These impulses are counted to calculate total precipitation.

  • The resolution (rainfall per tip) can be selected at order: 0.1 mm, 0.2 mm, or 0.5 mm.

Technical Specifications

  • Collecting area: 200 cm²

  • Resolution: 0.1 / 0.2 / 0.5 mm (selectable)

  • Accuracy: ±2.5 % (0–100 mm/h, 0.2 mm) / ±1.5 % (0–100 mm/h, 0.5 mm)

  • Maximum rainfall rate: 600 mm/h (0.2 mm) – 1000 mm/h (0.5 mm)

  • Operating temperature: 0 … +70 °C (standard), –20 … +70 °C (heated model)

  • Heater activation (HD2015R): Automatic at +4 °C

  • Power supply (heated model): 12/24 V dc ±10 %, ~50 W

  • Output type: Reed contact (normally closed, opens on tip)

  • Protection class: IP65

  • Dimensions: ∅189 × 274 mm

  • Cable section: ≥0.5 mm² (standard) / ≥2.5 mm² (heated model)

Installation & Maintenance

  • The device should be installed in an open area away from obstacles.

  • For measurement accuracy, it must be mounted perfectly level (built-in bubble level provided).

  • The cone filter prevents leaves and debris but requires periodic cleaning.

  • Special care is needed for power connections in the heated model.

  • Output impulses must be collected by a datalogger or pulse counter.

  • During transport the bucket is locked; unlock it at installation.
