FrequencyandAmplitude

The interactive player below enables you to adjust the frequency and amplitude. Frequency and amplitude are essential parameters in the understanding of ultrasonic gas leak detection. The term amplitude measured in decibels (dB) is the parameter that describes the sound level or volume of the acoustic sound. Frequency measured in hertz (Hz) is the parameter that describes the high and low pitches in acoustic sound.

In a plant environment there will be noise in a broad range of different frequencies. In Gassonic ultrasonic gas leak detectors there is a filter set to 25 kHz, which filters out noise sources that may otherwise interfere with the detector performance. Different areas will also have varying amplitude levels. Moreover, the amplitude level changes for different frequencies. For instance, the noise generated by a compressor will be higher in the lower frequencies compared to the higher ultrasonic frequencies (>20 kHz). Because the lower frequencies are blocked, the acousic gas leak detectors work efficiently even in very noisy plant areas.
