IEP-MIC / CONFIGURATION INQUIRY
Prepolarized IEPE Measurement Microphones
Acoustic pressure and acceleration. One acquisition plan.
A prepolarized capsule and a suitable IEPE preamplifier can share an IEPE-capable acquisition system with accelerometers. Acoustic sensitivity is specified in mV/Pa, not mV/g. Channel range and acoustic calibration need a separate review.

FIRST, DEFINE THE OPERATING WINDOW
Sensitivity, interface and acquisition requirements
These are request profiles. Confirm the selected model’s datasheet before ordering; the listed targets do not describe one universal configuration.
| Capsule requests | 1/2 inch or 1/4 inch |
|---|---|
| Acoustic field | Free-field response, application dependent |
| Output chain | Capsule + compatible IEPE preamplifier |
| Class 1 request | Evidence required for applicable complete measurement system |
| Calibration request | Acoustic sensitivity and frequency response |
Match the measurement to the test structure
Automotive NVH and wind-tunnel acoustics: document frequency band, peak sound pressure, microphone field correction and airflow protection. Confirm the acoustic calibrator fits the capsule.
Review an existing sensor model →Documents to review before release
Request capsule and preamplifier identities, overload limit, self-noise, environmental ratings and applicable calibration records. A capsule designation alone does not establish IEC 61672 system conformity.
Ask for available calibration method, traceability, frequency points and uncertainty. TEDS memory does not replace a current calibration record.
Cable, mounting and excitation belong in the same RFQ
Specify cable connector and pinout before selecting a cable. Magnetic mounts can reduce usable high-frequency response; holding force depends on surface and pull direction. Verify stud thread, seating surface, insulation and mounting torque. For a triaxial sensor, reserve three inputs.
Can I reuse an existing ICP® acquisition system?
Often, after checking current, compliance voltage, bias, signal headroom, coupling, connector and TEDS support. A matching sensitivity or connector is only part of the review.
Are price, stock and calibration included?
Request a configuration-specific quotation. Price, shipping date, accessory fit and calibration scope are confirmed in that quotation.
