Medium Fruit Growth Sensor

Fruit Growth Sensors for rounded and cylindrical fruits 7 to 45 mm

A series of absolute displacement sensors provides recording both size and growth rate of intact rounded fruits in three diameter ranges within 7 to 160 mm. Two phenomena affect fruit diameter: growth and internal water content. The growth component is usually dominant, however in some cases, the fruit may lose water which is manifested in the deceleration of growth rate or even shrinkage of the fruit. These manifestations may be a result of water stress, lack of light, or another limiting factor. Thus, the FI-type sensor allows investigation of the effect of irrigation rate and other environmental factors on both water balance and fruit growth. Another exciting application of the sensor is monitoring harvested fruits during storage.

SKU: P-S FI-SM Categories: ,

The FI-type sensor consists of an LVDT transducer mounted in a special clip and a DC powered signal conditioner. Standard cable length between sensor and signal conditioner is 1 metre.

Original parallelogram design of moving arms provides firm and straight positioning of the sensor’s flaps on the fruit under study.

FI-LM (large), FI-MM (medium) and FI-SM (small) models have different clips for providing three measurement ranges: 30 to 160, 15 to 90 and 7 to 45 mm, respectively.
