Differential Acoustic Emission Sensors Our differential sensors are identical to our general purpose sensors in physical, electrical and response characteristics, except that two signal leads (instead of one as for general purpose sensors) are brought out to attach to a differential pre-amplifier. By using a differential preamplifier, common mode noise is eliminated, resulting in a lower noise output from the preamplifier, and a higher electrical noise rejection in difficult and noisy environments. Noise improvements in the range of 2dB or higher can be expected using a differential sensor and preamplifier over a single ended general purpose sensor.
