SonicSniffer SSNF80k-Plus máy đo tần số siêu âm không tiếp xúc ( 1 ~80 kHz)

How it works The SonicSniffer® measures the frequency based on the ultrasound emitted by the horn. Simply place it close to the horn on the production floor and read the result on the display screen (the equipment may be under a continuous or intermittent operating mode).

SonicSniffer^® differentials

Pocket-size equipment running under very low power: It is lithium coin-powered (CR 2032), with average lifespan of 1-year on standby or 1000 uses Precision and calibratable test instrument: Frequency uncertainty of only ±8 Hz for the confidence interval of 2σ. We can offer SonicSniffer with traceable to SI (International Systemof Units) and/or accredited calibration certificate (optional service; see certificate example on the right). Magnetic fixing and memory: Making hands-free measurements possible. Noise immunity: ≥ 105 dB in the 0-5 kHz range to avoid disturbances by compressed air blowing nearby. Wide frequency range and high-sensibility: Measurements up to 80 kHz. Fast and smart: Low latency (0.1 s) and high refresh rate (10 Hz typical). Refined algorithm for measurement validation before it is displayed.

SonicSniffer^® applications

The SonicSniffer^® main application is to perform routine inspection of power ultrasonic equipment for the early detection of frequency shifts, which indicates the need for preventive maintenance. Frequency shifts alert users that something is not right, possibly avoiding equipment failure and saving expenses with new converters, boosters, horns, sonotrodes, blades and tips. Frequency shifts are due to many causes, such as joint deterioration, horn wear, cracks and converter failure. Joint deterioration is the most common issue because it is an inevitable. Over the time, it decreases the stack frequency, mechanical quality factor and overall efficiency because of the reduced effective contact area and increased friction of interfaces. Low efficiency leads to heating, which accelerates the mating surfaces fretting and the ultrasonic components fatigue in a vicious circle , ultimately leading to a catastrophic failure. By taking care of the stack joints, users may avoid triggering many other problems. SonicSniffer^® is also used to test the frequency of ultrasonic medical equipment and components, such as ultrasonic scalers tips and ultrasonic scalpels blades.
