The accelerometers are IEPE (lntegrated_Electronics PiezoElectric) sensors that produce an output voltage proportional to the input acceleration. The sensors feature a built-in preamplifier and a charge to voltage converter that transforms the high-impedance charge output from the piezoelectric ceramic (Lead Zirconate Titanate, PZT) into a low-impedance voltage output that is suitable to drive long cables. ASC's high-temperature IEPE sensors operate on a 2-20mA constant-current supply and use a two-wire coaxial cable for power input and signal output.

Type P401A15 is designed for use in demanding high-temperature (150°C) vibration monitoring applications. The sensor is based on a piezoelectric annular shear design, which provides excellent immunity against base strain and temperature transients. ASC Type P401A15 features a stainless steel housing that is rugged, corrosion proof and chemical resistant. The sensor incorporates a welded hermetic contruction with the industry standard 10-32 UNF connector and can withstand shocks up to 5000g‘s. Type P401A15 has a through hole for centre bolt mounting, which permits 360° cable orientation. ASC Type P401A15 operates over a wide temperature range from -55°C to +150°C.
