Sensor Name and Type: Circumference Dendrometer 1, Type DC1

Purpose: Designed for measuring the circumference growth of trees.

Suitable Plant Size: Diameter range of 5 - 32 cm.

Limitations: The mechanical pressure exerted by the wire cable varies with tree size, affecting data comparability across different diameters.

Sensor Range: 11 mm

Resolution: Infinite sensor resolution; reading resolution depends on the data logger used (e.g., CR1000: 1.5 µm, DL18: 0.2 µm).

Accuracy: Dendrometer dependent with a maximum of ±4.5% of reading. Logger dependent accuracy varies (e.g., CR1000: ± (0.04% of reading +4.4 µm), DL18: ±0.1%).

Temperature Coefficient: Sensor: <0.2 µm/°C; Wire cable: <1.4 ×10-6/K.

Linearity: Less than 1%.

Environmental Conditions: Suitable for outdoor use in temperatures ranging from -25 to 70°C and 0 to 100% relative humidity.

Weight: 13 g without cable.

Power Supply: Requires a stabilized voltage of 0.5 – 10 VDC with negligible power consumption.

Material: Constructed from stainless steel and aluminium.

Cable Length: 5 m, extendable up to 100 m.
