Micro Load Cell Sensor 2kg Miniature Weight Transducer 4.4 lbf
Miniature Weight Sensor FMZT offers 2kg rated capacity,model FMZT utilizes 1000 ohms
high resistance strain gauges,which is more energy-efficient
compared to commonly used 350 ohms strain gauges. Lightweight
design with only 3.3 grams self weight, micro load cell FMZT is
suitable for high accuracy weight measurement applications with
restricted space and tight budget.

A Load Sensor is a transducer that converts mechanical load into electrical
signal which is proportional to the load being applied.The measured
load or force causes deformation of the measuring element(elastic
body),the bonded strain gauge deforms accordingly which will cause
the resistance change of the wheatstone bridge,under constant power
supply, the output signal between Sig+ and Sig- will change
proportionally, thus the load/force can be measured by measuring
the output signal from the load cell which is normally within 0-5mV
for model FMZT. Overloading is the most common cause of loadcell failure, a
loadcell is just like a spring in certain aspects, which will be
damaged if overstretched or overloaded. A machanical stop(refer to
below picture) can be used to protect the sensor from excessive
deformation. The deformation distance can be determined by loading
the sensor with rated capacity, then adjust the meachnical stop to
reach the bottom of the transducer. In most cases, the load
transducer will be used to measure load at 40-80% of the full
scale, thus the deformation distance can be adjusted using
reference load which is a bit higher than the maximum target load
to be measured instead of the rated capacity.
