R50I-AST Sensor Integral Preamplifier Acoustic Emission Sensor Description and Features Operating Specifications PAC’s integral preamp sensors were specifically engineered to attain high sensitivity and have the capability to drive housings that are treated to minimize RFI/EMI interference. Care has also been taken to thermally isolate the critical long cables without the need for a separate preamplifier. Incorporating a low-noise input, 40 dB preamplifier and a filter all inside the sensor housing, these transducers are completely enclosed in metal stainless steel (or aluminum) input stage of the preamplifier in order to provide excellent temperature stability over the range of -35º to 75º C. Their integrated Auto Sensor Test (AST*) capability allows these sensors to pulse as well as receive. This feature lets you verify the sensor coupling and performance at any time throughout the test. Completely shielded crystal for maximum RFI/EMI immunity toring applications and is particularly well suited to such applications as welding monitoring and control. This sensor is useful in very noisy plant and process moni- Frequency response of the R50I-AST. 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. 195 Clarksville Road, Princeton Junction, NJ 08550 Phone: 609-716-4000 Fax: 609-716-0706 Email: sales@pacndt.com Internet: www.pacndt.com A Member of MISTRAS Group Inc.
