Ultrasonic Anti Collision Application :
The ultrasonic Anti Collision Device system works on the principle of Ultrasound waves. The Sound emitter and sound detector are tuned at the same Sound frequency of 40Khz. When the transmitter sends a burst of ultrasonic sound, it is reflected back by the walls of the crane and the receiver detects it and activates an alarm signal and stops or reduces the speed of the crane.The time taken after the burst is send and received and with speed of sound Distance is calculated.There is a Display which shows Distance in meters. If the obstacle is in range then by rotating the Knob, Relay range can be adjusted and another relay can be adjusted by directly pressing the switch.Thus if two cranes are out of range they will operate in normal speed. The sensing Distance is adjustable from 0.01m to 5 meters. The Device is designed for crane applications and is suitable to work for 24x7 hrs. This product does not require laser pointing device.
What Goes into the Making of a Transducer?
The main component of a depth transducer is the piezoceramic element. It is the part that converts electrical pulses into sound waves, and when the echoes return, the piezoceramic element converts the sound waves back into electrical energy. Piezoceramic elements are most often in a disk form,but they may also be in the shape of a bar or a ring. A transducer may contain one element or a series of elements linked together called an array. A transducer is made up of six separate components.
