Sensor body scale 50kg load cell resistance strain half bridge sensor 50kg เซนเซอร์ load cell ขนาด 34x34mm วัดน้ำหนักสูงสุด 50 kg ตัวอย่างการใช้งาน https://www.instructables.com/id/Arduino-Bathroom-Scale-With-50-Kg-Load-Cells-and-H/ The internal is a 1000 ohm half-bridge strain gauge, the measuring range is 50kg load cell, half bridge structure. Internal principle When measuring, the outer side is correctly applied with external force. The strain beam part of the E-shaped sensor (that is, the beam arm with the white rubber in the middle of the strain gauge) and the outer side are to form a shearing force in the opposite direction, that is, the middle The strain beam must be able to undergo a bending change under the force, and there should be no obstruction on the other side of the strain beam. Inside the sensor is a set of half-bridge strain gauges, which can be used in the following three ways: 1. Use one sensor with external resistor to form a full bridge measurement. The range is one sensor's range: 50kg. The external resistance is higher. 2. Use two sensors to form a full bridge measurement. The range is the sum of the ranges of the two sensors: 50kgx2=100kg. 3. Use four sensors to form a full bridge measurement. The range is the sum of the ranges of four sensors: 50kgx4=200kg Mechanical Dimensions:
