Beta, Gamma, Alpha + Gamma CELLs
Cost Effective Leak
CELL ground microphones detect the noise, generated by leaks in buried pipes, reaching the ground surface. The CELL's ground microphone consists of a special high sensitivity sensor mounted in a unique suspension system, giving maximum isolation from external noise interference.
Three option are available for the ground microphone system: the Beta system consist of a ground-microphone with a small 'belt' amplifier. The Gamma system consist of a ground-microphone with an advanced amplifier unit providing filtering and display of leak signal strength. The Alpha + Gamma system is a combination of the Alpha electronic leak listening probe, the Gamma ground microphone and the advanced amplifier unit.
CELL's design, with latest technology to detect noise beyond the responsiveness of the human ear, enables effective leak listening and location. The ground microphone consists of a very sensitive piezo-ceramic sensor with extended low frequency response. It is mounted in a wind-proof housing of rugged, stainless steel construction.
With Beta CELL the leak signal is amplified by a small amplifier which is attached to the operator's belt. The belt amplifier unit is designed using low power, ultra low noise analog signal processing circuitry for optimum performance.
With the Gamma CELL and Alpha + Gamma CELL combination the advanced amplifier unit has a low noise design with the addition of variable filters, visual noise indication relative to the last measurement position, and 50/60 Hz notch filters. The display is back-lit, giving clear, easy to read, results under all lighting conditions. A variable headphone gain control with 10 segment LED bar-graph indicator, gives instant indication of signal strength. 'Hold' control freezes signal strength display for easy interpretation of results.
