Description: In industrial automation, the most important component is the signal. However, the signals have to be amplified for effective use by various devices. This is why you need sensory amplifiers. Sensory amplifiers use current sense resistors that help convert the current load to a small voltage in the power rail before amplifying it. In most cases, current running in the power rail ranges from 1A to 20A. This means they use resistors with a capacity of 1 to 100 mΩ. The amplifiers can be broken into two: operational amplifiers and differential amplifiers. The operational sensory amplifier is a type of DC-coupled electronic voltage system featuring a differential output. Here, the amplifier increases the original signal hundreds or thousands times. In the case of the differential amplifier, it utilizes the variation between two voltage inputs. Then, it suppresses voltage that is considered common to the two inputs and generates a single (amplified) voltage output. So which is the better option for your operations?
