WARNING: Not To Be Used for Personnel Protection Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or deenergized sensor output condition. P/N 119287 Rev. H 5/22/2013 0 119287 2 WORLD-BEAM QS18U Ultrasonic Sensors 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: D = ct / 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: In metric units: Cm/s = 20 273 + TC In English units: Cft/s = 49 460 + TF Cm/s = speed of sound in meters per second Cft/s = speed of sound in feet per second TC = temperature in C 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 QS18U 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 (-4 to +140 F) range. NOTE: * 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 7% of the sensing distance. After 5 minutes, the apparent switchpoint will be within 0.6% of the actual position. After 25 minutes, the sensing position will be stable. Sensor Programming Green/Red Power/Signal Strength LED Yellow/Red TEACH/Output Indicator LED Push Button (IP67 models only) Two TEACH methods may be used to program the sensor: * Teach individual minimum and maximum limits, or * Use Auto-Window feature to center a sensing window around the taught position 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 white wire of the sensor to 0V dc, with a remote programming switch between the sensor and the voltage. Figure 1. Sensor Features Programming is accomplished by following the sequence of input pulses (see programming procedures). The duration of each pulse (corresponding to a push button "click"), and the period between multiple pulses, are defined as "T: 0.04 seconds < T < 0.8 seconds." 2 www.bannerengineering.com - tel: 763-544-3164 P/N 119287 Rev.
