Systems Ultrasonic Rodent System SYSTEM OPERATION Model-URRS-12T consists of one main console, 12 transducers & a cable bundle of 0.25 Sq.mm 2 core cable. The main console is a microcontroller based system with embedded power electronic circuits to generate a pattern of ultrasound waves at 800mW power output per transducer. All parameters such us start frequency, end frequency, sweep time, wave pattern etc are pre programmed in the system. The sound waves are at high frequency (well about 20HKz which is not hearable to human ear) The transducers emit intensive sound at high decibels (that are audible and painful to pests but inaudible and harmless to humans). The rodents usually leave the area being protected by ultrasound. They do not get killed.
