Dendrometer: Environmental Measurement Japan

Dendrometer

Dendrometer Circumferential MIJ-02 Rotary Type3
Optionally can be changed to Nondestructive
Target：Φ above 40mm 

Feature
・Selectable nondestructive or screw mount (Need to purchase nodestructive KIT for nodestructive method)

・Wire typed dendrometer allow measurement immediately after set to measurement object.

・Potentiometer and pulley can be rotate 30 degree

・Set the wire position close to the measurement object (5mm) that allow to obtain absolute value

・Wide measurement Range (30mm)

・Ratiometric output lead to avoid potentiometer thermal characteristics

・Wide range of  measurement Object (Measurement Object above Φ40mm～inifinity)
Dendrometer MIJ-02 TypeII Rotary
For Trunk Circumference
Target: Φ40mm~infinity
Discontinued		 MIJ-02LM TypeII Absolute Linear
Linear Dendrometer
Target: designed specifically displacement measurement for xylem, or bark and cambium.
dendrometer dendrometer xylem cambium

Feature 

・MIJ-02 rotary can measure immediately after set to plant.

・Wire position is very close to trunk (5mm distance), so that it can measure exact value of trunk movement

・Pulley diameter is37mm. Range of electrical and mechanical rotation angle is 90°.
(These combination lead wide measurement range of 29mm; when it reach to max then user can reset the wire)

・Easy operation by equipping wire stopper

・Ratiometric output lead to avoid potentiometer thermal characteristics

Feature 

・Basically, target is the tree trunk

・Adjustable securing bracket and spring rate allow to measure thin branch, fruit, crops and etc.

・Equipping the non-backlash potentiometer allow to read daily expansion and contraction.

・Reduced thermal characteristic by offsetting the linear thermal expansion coefficient of shaft and fixed nail.

・Avoid the thermal characteristic of potentiometer by using ratiometric output

・Minimum friction help to setting spring constant low
