Description Working principle of resistance strain gauge is based on the strain effect produced when a conductor or semiconductor material that is mechanical deformation under the action of external forces, the resistance value of the corresponding changes. The strain gauges attached to the object to be measured so as to be measured strain was bent together, so that the inside of the metal foil as the strain on the bend. Many metal during mechanical bending resistance will change. Feature - Color: As Shown. - Material: modified phenolic substrates. - Size: 3 x 1.5cm. - Voltage: 5V - The analog output voltage: 0-3.5V - Board size: 32 X 17 mm - Resistance: 350 Ohm - Fatigue life:> 10 million times - Flux: Ordinary solder rosin - Strain limit: 2% - Other Feature: Reverse protection diode Analog Output Zero potentiometer - Long Fatigue life, more than 10 million times, longer than other similar products. - Reverse protection diode, protect equipment and test equipment are not damaged in emergency situation. - Analog Output, The direct output analog signal can be read and processed directly by the next level device. - Note:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3 cm.Package list: 1 x Strain gauge Bending detection Test Sensor Module
