Product Description

Size: 28mmX24mm

Internal 1000 Ohm half-bridge strain gauge load cell, range is 50kg, half-bridge structure.
When measuring, the correct force is applied to the outer side of the strain E-shaped beam portion of the sensor (i.e., a strain gauge affixed to the middle, with a beam of white plastic cover arm) and the outside edges to form a shear force in the opposite direction, i.e., in the middle of strain beam bending necessary changes can occur under stress, strain beam side by another force can not have a barrier.

The sensor use the following three methods:

1. using a sensor with external resistors full bridge measurement range of a sensor range: 50kg. Higher requirements for external resistor
2. the use of only two full-bridge sensors measuring range is the range of the two sensors and: 50kgx2 = 100kg
3. the use of four full-bridge sensors measuring range is the range of four sensors and: 50kgx4 = 200kg
