A Mod U-GAGETM S18U Series Sensor -- Discrete Output Principles of Operation Ultrasonic sensors emit one or multiple pulses of ultrasonic energy, which travel through the air at the speed of sound. A portion of this energy reflects off the target and travels back to the sensor. The sensor measures the total time required for the energy to reach the target and return to the sensor. The distance to the object is then calculated using the following formula: ct D= 2 D = distance from the sensor to the target c = speed of sound in air t = transit time for the ultrasonic pulse To improve accuracy, an ultrasonic sensor may average the results of several pulses before outputting a new value. Temperature Effects The speed of sound is dependent upon the composition, pressure and temperature of the gas in which it is traveling. For most ultrasonic applications, the composition and pressure of the gas are relatively fixed, while the temperature may fluctuate. In air, the speed of sound varies with temperature according to the following approximation: Cm/s = speed of sound in meters per second C = 20 273 + T m/s C Or, in English units: Cft/s = 49 460 + TF TC = temperature in C Cft/s = speed of sound in feet per second TF = temperature in F Temperature Compensation Changes in air temperature affect the speed of sound, which in turn affects the distance reading measured by the sensor. An increase in air temperature shifts both sensing window limits closer to the sensor. Conversely, a decrease in air temperature shifts both limits farther away from the sensor. This shift is approximately 3.5% of the limit distance for a 20 C change in temperature. The S18U series ultrasonic sensors are temperature compensated. This reduces the error due to temperature by about 90%. The sensor will maintain its window limits to within 1.8% over the -20 to +60 C range. NOTES: * Exposure to direct sunlight can affect the sensor's ability to accurately compensate for changes in temperature. * If the sensor is measuring across a temperature gradient, the compensation will be less effective. * The temperature warmup drift upon power-up is less than 1.7% of the sensing distance. After 10 minutes, the apparent distance will be within 0.3% of the actual position. After 25 minutes, the sensing distance will be stable. 2 P/N 108964 rev.

The sensor may be programmed either via its push button, or via a remote switch. Remote programming also may be used to disable the push button, preventing unauthorized personnel from adjusting the programming settings. To access this feature, connect the gray wire of the sensor to 0 - 2V dc, with a remote programming switch between the sensor and the voltage.
