AC100 gas leaks by looking for changes in the spectrum of  the received acoustic signal. To do this, the AC100  employs a high performance microphone and digital  signal processing (DSP) technology to continuously  monitor the acoustic signal. The wide dynamic range and spectral resolution enable  the sensor to provide both superior sensitivity and false  alarm discrimination. The AC100 Acoustic Sensor can be connected directly  to the ATX10 Transmitter, or mounted remotely using an  optional Sensor Termination Box (STB).  3.46 (8.8) 4.7 (11.9) 2.7 (6.9) 3.77 (9.6) 5.16 (13.1) 5.2 (13.2) 5.86 (14.9) 12.33 AC100 WITH ATX10 AC100 WITH ATX10 OR STB AC100 WITH STB A2610 Figure 1—Dimensions of Acoustic Detector in inches (Centimeters)
