Concept circuit: the conditioner supplies current; the sensor contains impedance-conversion electronics.

01 / CONFIGURE THE MEASUREMENT

Start with your axis count and usable bandwidth

All IEPE product families ↗
Uniaxial IEPE accelerometers conceptual measurement chainIEP-UNI

Uniaxial IEPE accelerometers

Specify a single-axis IEPE accelerometer by sensitivity, usable frequency band, mounting and excitation. Compare 10–1000 mV/g request profiles.

Define your configuration →Triaxial IEPE accelerometers conceptual measurement chainIEP-TRI

Triaxial IEPE accelerometers

Plan three-axis IEPE measurements with 10 or 100 mV/g request profiles, 4-pin fan-out cabling, mounting and TEDS review.

Define your configuration →Modal & seismic IEPE sensors conceptual measurement chainIEP-MOD

Modal & seismic IEPE sensors

Define low-frequency dynamic measurements using high-sensitivity IEPE sensor request profiles, noise bandwidth and overload headroom.

Define your configuration →IEPE measurement microphones conceptual measurement chainIEP-MIC

IEPE measurement microphones

Plan an acoustic and vibration acquisition chain with prepolarized measurement microphones, IEPE preamplifiers and calibration requirements.

Define your configuration →IEPE signal conditioning & DAQ conceptual measurement chainIEP-CON / IEP-DAQ

IEPE signal conditioning & DAQ

Specify 1–8 channel IEPE constant-current conditioners or synchronous USB/Ethernet acquisition, with excitation, AC output and software review.

Define your configuration →

02 / KEEP YOUR EXISTING ACQUISITION WORKFLOW

Review an ICP® replacement by more than mV/g

Bring your PCB, Brüel & Kjær / HBK, Dytran or Kistler model number. Compare electrical headroom, frequency response, mass, mounting and pin assignment before selecting an IEP configuration.

IEPE vs. ICP®

IEPE means Integrated Electronics Piezo-Electric. ICP® is PCB Piezotronics’ trademark for its integrated-electronics sensors. They use the same broad constant-current measurement principle; compatibility still depends on the actual sensor and input specifications.

Understand current, bias and AC signal →

03 / PLAN THE ARRAY, INCLUDING THE DETAILS

16–64 sensors: count axes, channels and cables

Automotive NVH

Count X/Y/Z channels, define cable routing and set peak acceleration and temperature requirements at each mounting point.

Structural modal testing

Control mass loading, channel sensitivity and phase. Define the lowest mode and the record length before choosing a high-sensitivity sensor.

Shaker & machinery testing

Check overload recovery, mounting stiffness and the high-frequency chain. Use the actual conditioner current and cable capacitance.
