ISAS3-150-V01

The ISAS03-150-V01 is a piezoelectric AE-sensor with integrated preamplifier based on intrinsically safe electronic design making it suitable for installation in ATEX zone 0 environment. ISAS3-150-V01 has a recommendet bandwith for application from 95 kHz to 300 kHz with peak sensitivity at 150 kHz. The integrated preamplifier has 20dB gain and supports Automatic Sensor Test (AST) for judging sensor coupling. Benefits of ISAS3 are amongst others the intrinsically safe and robust sensor design, the ATEX certification, ingress protection class IP 68 and water and oil resistance up to 12 bar.
