automotive sensors - resistive sensor

Resistive sensor is to be measured, such as displacement, strain, force, acceleration, humidity, temperature, and other such physical quantity conversion formula into a resistance value of such a device. There are resistance strain, piezoresistive, thermal resistance, thermal, gas, humidity and other resistive sensors.Automotive Sensor Camshaft - resistance strain sensorThe resistance strain gauge sensor with metal strain effect, that produces mechanical deformation under external force, so that the resistance value corresponding changes ensued. Resistance strain gauges are mainly two types of metals and semiconductors, metal strain gauge metal wire type, foil, film type of the points. Semiconductor strain gauge with high sensitivity (typically wire type, foil several times), transverse effect is small.
