N03B00

The N03B00 is a lightweight, compact modal impact hammer with a built-in IEPE quartz force sensor, offering fast dynamic response, high natural frequency, high resolution and low electrical noise. With 10.0 mV/N (44.5 mV/lbf) sensitivity and a ≤ 0.5 kN pk (≤ 112 lbf pk) range it is the most sensitive hammer in the family, with a 0.5 kN (112 lbf) range and 0.18 N resolution for light, compliant parts. Typical uses include modal analysis of small components, PCBs and light brackets, resonance identification on delicate assemblies and structural checks where a light tap is enough.

The quartz sensing element gives ≤ 1% non-linearity and ≤ 1% repeatability with a resonance ≥ 40 kHz, so the force pulse is captured faithfully, and the built-in IEPE circuit outputs a ±5 V full-scale signal on a standard BNC connector that plugs straight into any IEPE-compatible analyzer or DAQ. Carbide, nylon and rubber tips plus a 73.5 g extender mass ship in the case, so one hammer covers hard, short impacts for high-frequency content through soft, long impacts for low-frequency excitation on the same structure.

Tips for every frequency range

Interchangeable carbide, nylon and rubber tips shape the impact pulse from a hard, high-frequency tap to a soft, low-frequency push, and the 73.5 g extender mass adds energy for larger structures. All ship in the portable case.

Clean, repeatable force pulse

Quartz sensing element with ≥ 40 kHz resonance, ≤ 1% non-linearity and ≤ 1% repeatability. 0.18 N (0.04 lbf) resolution and 120% overload capacity, with a settling time of > 30 s between impacts.

Built-in IEPE electronics

IEPE circuit with 2–20 mA constant-current excitation, 8–12 V bias and a ±5 V full-scale output on a BNC connector, so the hammer runs from the same IEPE input as your accelerometers. Stainless-steel head with epoxy sealing, rated −55 to +120 °C.
