Analog ultrasonic sensor
RPS-412A high-accuracy (±0.002 in. or 0.05% of range, whichever is greater, at 25 °C) analog ultrasonic sensor has a built-in temperature compensation target that monitors and compensates for air temperature 50 times a second.
RPS-412A high-accuracy (actors that influence the speed of sound. Device takes advantage of PLC and computer analog input cards to determine system resolution as well as the zero and span.
