Principle and Application of Underwater Ranging Transducer

  Principle and Application of   Underwater Ranging Transducer   Principle of Measurement   The ultrasonic wave emitted by the ultrasonic probe is transmitted through water, meets the target to be measured, is reflected and then returned to the ultrasonic probe through water, because the time of transmission and reception can be known, according to this time × speed of sound ÷2= the distance between the probe launching surface and the target to be measured.   Computational Formula: D ＝ C*t/2   (Divided by 2 because the sound wave actually travels back and forth from transmission to reception, where D is the distance, C is the speed of sound, and t is the time).   If the time difference between transmission and reception is 0.01 seconds, the speed of sound in fresh water at room temperature is 1500 m/s. 1500 m/s x 0.01 s =15 m 15 meters ÷2=7.50 meters That is, the distance between the probe launching surface and the measured target is 7.50 meters. ...

Ultrasonic Underwater Ranging Transducer

图片
  Description Introduction:   The underwater ranging transducer uses ultrasonic waves to transmit in the water, reflects back the measured object, measures the distance between the sensor and the measured object, and transmits it to ships, buoys, underwater unmanned vehicles and other equipment, which can be used as obstacle avoidance or underwater ranging. Products meet IP68 protection grade level, can be 10 meters deep under water soak for a long time, will not damage. Main Parameter:   Measurement output: the distance between the probe transmitting surface and the measured target; Sensor connection mode: M36 x 1.5 thread with fixing nut; Shape: cylinder; Other sensor connection methods: requirements need to be made, can be customized threaded or flange connection methods. Blind area range: according to the measurement range, the blind area is different; Protection level: IP68; Power supply voltage range: DC 12.0V ~ 30.0V; Supply voltage and current: DC 24V, current ...

Ultrasonic Underwater Communication Transducer

图片
  Description Introduction: Ultrasonic underwater communication transducer is a kind of equipment which converts electrical signal into acoustic signal and transmits data underwater. It converts electrical signals into mechanical vibrations through the piezoelectric effect, and then generates ultrasonic waves propagating underwater to achieve long-distance communication. Parameter: Distance: 100m or Custom. Frequency: 40KHZ. Communication Rate: 96bps. Transmitter Data: 1 to 12 characters. Bit Error Rate: ≤8% ( Related to the test environment). Communication Mode: RS485, modbus protocol. Withstand Voltage: 100m depth. Operating Environment: Water depth greater than 2 meters, away from the motor and frequency conversion equipment. Power Supply: 12V±10%, Receiving power 0.9W/ transmitting power 5W. Protection Grade: IP68 Working Temperature: 0℃～+60℃ Joint Thread Size: M33*1.5 Storage Requirements: Storage ambient temperature: -20～+60℃; Storage envi...
