PCM60 Ultrasonic Distance Measuring Sensor Introduction: Ultrasonic testing is a non-contact and wear-resistant detection of the object being tested using acoustic media. Ultrasonic sensors can detect both transparent and colored objects, metallic and non-metallic objects, as well as solid, liquid, or powdered substances. The surrounding environmental conditions, such as smoke, dust, or rain, will hardly affect the detection performance of ultrasonic sensors. Ultrasonic ranging principle: The ultrasonic pulse emitted by the transmitting ultrasonic transducer propagates through the propagation medium to the measured medium, reflects, and then returns to the receiving transducer through the transmitting medium, measuring the time it takes for the ultrasonic pulse to propagate in the transmitting medium from transmission to reception. Based on the speed of sound in the transmission medium, the distance from the transducer to the surface of the medium can be calculated. Thus determining the liquid level. Therefore, we can calculate the distance from the probe to the reflection surface as D=C * t/2 (divided by 2 because the sound wave actually travels back and forth from emission to reception, where D is the distance, C is the speed of sound, and t is time). This sensor has an emission angle of about 6 ° and is suitable for narrow spaces. For example: intelligent garbage bin level monitoring, parking space status monitoring. Technical parameters: Power supply: 10.8VDC~26.4VDC Measurement range: 250-3500mm Measurement accuracy: ± 30mm Resolution: 1mm Response time: 1 second Launch angle: 7 ° Environmental temperature:- 20℃～60℃ Protection level: IP67 Wire length: 2m (other wire lengths need to be customized)
