DC1 Circumference Dendrometer (for tree diameters from 5 to 30 cm)

The sensor is mounted on a wire cable with a very low coefficient of thermal expansion on the plant. The slide rings reduce the friction between the wire cable and the tree bark. They also decrease the pressure of wire cable on the tree.
Please note the essential difference between the various circumference dendrometers.

Advantages

■ Suitable for diameter 5-30 cm

■ No injury to plants

■ Easy installation

■ Stability against wind, snow, falling small branches and small fruits

■ Readings directly correspond to the circumference changes


Limits

■ Because the elastic force of the sensor is exerted in tangential direction (wire tension), the contact pressure between cable wire and stem depends on the curvature of the stem, i.e. the stem diameter (analog to the Young- Laplace equation) The result is that the larger the stem radius, the lower the contact pressure between cable wire and stem surface. Measurement data between stems of highly divergent radiuses is therefore not comparable (cf. DC2).

Delivery

■ Complete with 5 m cables and 1 m wire cable
