Medium Frequency & Low Noise Integral Preamp Acoustic Emission Sensor Operating Specifications The CH15I sensor is a medium frequency, resonant, acoustic emission sensor with an integral, low noise, filtered, 40 dB preamplifier that can drive up to 1000 feet of cable. The sensor comes standard with PAC’s unique “Auto Sensor Test” (AST*) function. The CH15I features a strong, insulated, lightweight, aluminum alloy, integrated body structure that is color-coded blue to identify the sensor model. This sensor’s outside shell is anodized, providing a nonconductive finish to prevent any possible electric shorts from metal testing structures. It is the same size and has the same frequency response and sensitivity as the R15I sensor, but the EMI shielding ability of the CH15I has been improved by more than 300% compared with previous versions.

Calibration based on ASTM E1106; Calibration based on ASTM E976. * AST — Auto Sensor Testing feature allows AE systems to control the sensor as a pulser and a receiver at the same time. It can therefore characterize its own condition as well as send out a simulated acoustic emission wave that other sensors can detect, so the condition of the nearby sensors also can be tested.
