Piezoelectric IEPE Technology
ASC’s high-temperature centre bolt accelerometers are made of piezoelectric ceramics and
are usable over a wide frequency range from 0.5Hz to 15kHz. The accelerometers are IEPE
(Integrated 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.

ASC’s high-temperature IEPE uniaxial accelerometer, P401A15, is an analog voltage output
sensor. 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.
