dendrometers for small fruits

LVDT Fruit DendrometerThe FI-XSM absolute displacement sensor provides recording both size and growth rate of intact small rounded fruits within 4 to 30 mm in diameter.

The FI-type sensor consists of an LVDT transducer with a hanging spring, and a DC powered signal conditioner. Standard cable length between sensor and signal conditioner is 1 meter.

The probe is connected by a standard 1-meter cable to the waterproof box with the signal conditioner inside.

The output cable length should be specified in the order if required.
