Ultra-Sonic Sensor Boasts High Accuracy

A new analog ultra-sonic sensor has has an accuracy of ±0.002" or 0.05% of range, whichever is greater at 25°C. It also has a built-in temperature compensation target to monitor and compensate for air temperature 50 times/sec. Additionally, the sensor compensates for changes in relative humidity, barometric pressure, and other factors influencing the speed of sound. Housed in a 47 mm stainless steel barrel, which is electrically isolated from the sensor electronics,the RPS-412A accepts an input voltage of 20 to 30 Vdc and produces a 0V to 10V fixed analog output. The device is designed to take advantage of today’s PLC and computer analog input cards. The analog input card determines the resolution of the system.
