Radius Dendrometer Type DR Technical Specifications ECOMATIK GmbH Muenchner Str. 23 D-85221 Dachau/Germany Tel.: +49 8131 260 738 Fax: +49 8131 260 736 e-mail: [email protected] website: www.ecomatik.de Radius dendrometer Name of the Sensor Use area Suitable for plant diameter Range of the senor Resolution Temperature coefficient of the sensor Linearity Environment Weight of the sensor without cable Type DR1 Type DR3 (former name DR) slow/normal growing species > 8 cm fast growing species 11 mm 25.4mm The resolution of the sensor itself is infinite. The resolution of readings is determined by connected data logger, e.g. CR1000:1.5 µm CR1000: 3.3 µm Dendrometer logger DL18: 0.2 µm Dendrometer logger DL18: 0.5 µm Dendrometer dependent: Max. ± 4.5% of reading Max. ±1.97% of reading (stable offset) (stable offset) Data logger dependent, e.g.: CR1000:±(0.04% of reading+4.4µm) CR1000:±(0.04% of reading+10µm) Dendrometer logger DL18: ±0.1% Dendrometer logger DL18: ±0.1% < 0.2 µm / °C in the whole range <1% < 0.7% Outdoor condition: -25 to 70C air temperature, 0 to 100% relative air humidity 13 g Power supply Stabilized Vex of 0.5 – 10 VDC, power consumption practically zero Material Cable length Stainless steel and Aluminium 5 m, extenda
