TECHNICAL DATA UPR-A-1500-TOR-24-CAI-Ex Measurement range Linearity Linearity over full temperature range Hysteresis of switching point, axial Operating frequency Output speed analog output Average power consumption Ripple of supply voltage Reverse polarity protection Short circuit protection Protection class Operating temperature Pressure area Housing material nickel plated brass Status indicator ATEX designation The accuracy can be improved beyond by teaching the sensor only after it has reached its thermally stable state (e.g. after 30 minutes). The analog sensor automatically recognises the...

In scanning mode, the target reflects a portion of the ultrasound, which in turn is detected by the sensor. The switching points are set by attaching the voltage supply -UB (0 V) or +UB (+24 VDC) during 1...5 s to the Teach input. The two measuring limits are set by attaching the voltage supply -UB (0 V) or +UB (+24 VDC) to the Teach input for 1...5 s. During the teaching process the flashing LED indicates if the sensor detected the target: • Yellow flashing LED: detected The lower evaluation limit (0 V or 4 mA) can be taught with -UB and the upper evaluation limit (10 V or 20 mA) with +UB. It...

Ultrasonic sensor of the UPR-A ATEX series with option Y have the following two additional functions: Synchronisation: If several sensors are placed close together and scan the same object or if a common background is present, the sensors must be synchronized. For this, the Teach/Sync. wires of all sensors (max. 6 sensors) are interconnected. Important is the order: 1. teach each sensor individually (!) 3. interconnect all Teach/Sync. wires 4. power on again only when everything is wired! Suppression mode: This additional function is interesting, for example, in level measurement with troublesome...

Environmental Influences Ultrasonic sensors are made for the use in atmospheric air. Environmental Influences like rain, snow, dust or smoke have influence on the accuracy of the measurement. However, measurements under pressure (higher that the atmospheric pressure) are not possible with ultrasound sensors. Strong wind or air turbulences may lead to instability in measurement values. A flow speed up to a few m/s is unproblematic and will have no influence on the sensor's accuracy. Target Influences • Liquids are excellently detectable with ultrasound. A classic application for ultrasonic sensors...
