|Ultrasonic Baths manufactured by Ultrawave Limited are tested to comply with European "CE' mark with respect to the Low Voltage Directive (LVD) and Low Electromagnetic Compatibility (EMC). |
In certain situations, interference with radio signals is experienced when ultrasonic circuits are in operation.
The interference can be generated from two sources...
It is a relatively simple modification to cure mains-borne interference. Usually a filter in the mains supply circuitry within the machine will stop interference with computer equipment, process control units and radios.
- Transmission through mains wiring.
- Radiation from cases and liquids.
Radiation from cases and liquids is often impossible to cure, siting radios and ultrasonics away from each other will generally remove the problem. Modern higher powered small ultrasonic baths have ferrite components generating harmonics within the radio frequency band, a radio receiver in close proximity to a bath will often pick up this radiated interference. Moving the radio or bath away will reduce this effect markedly.
This type of radiated interference will not affect computers or process control equipment as they have no radio frequency circuits to pick up these radiated signals.
