MISTRXS A World of NDT Solutions Products & Systems Division Product Data Sheet D9202B Sensor OPERATING SPECIFICATIONS DESCRIPTION AND FEATURES D9202B is a wideband differential sensor with a very high sensitivity. It has a very good frequency response over the range of 400 - 800 kHz. Differential sensors differ from their general purpose counterparts by employing two sensing elements with opposite polarization directions. The two signal leads feed into a differential pre-amplifier which eliminates commonmode noise resulting in a lower noise output from the pre-amplifier. Noise improvements to the tune of 2 dB can be achieved using differential sensors over a single ended sensor. This sensor features a rugged steel construction with an integrated twin axial cable exiting on the side. APPLICATIONS Differential sensors are used in environments were very low level AE signals need to be processed, they are particularly useful in environments with high background noise. This sensor is well suited for structural health monitoring of large structures like storage tanks, pipelines etc. Wideband sensors are well suited for research applications where a high fidelity AE response is required. It can be easily Completely enclosed crystal for RFI/EMI immunity Connector Locations ordering information and accessories mounted using epoxy.
