732-1D

Product catalog summary

Dynamic Specifications:
Sensitivity at 25°C is 10 mV/g with an acceleration range of 500 g peak. Amplitude nonlinearity is 1%. The frequency response is ±5% from 1.0 to 15,000 Hz and ±3 dB from 0.4 to 22,000 Hz. The resonance frequency when mounted is nominally 28 kHz. Maximum transverse sensitivity is 5% of axial. Temperature response varies from -10% at -50°C to +5% at +120°C.

Electrical Specifications:
Requires a voltage source of 18-30 VDC and a current regulating diode of 2-10 mA. Electrical noise equivalent is 250 µg for broadband 2.5 Hz to 25 kHz. Spectral noise is 20 µg/√Hz at 10 Hz, 4 µg/√Hz at 100 Hz, 2 µg/√Hz at 1,000 Hz, and 2 µg/√Hz at 10,000 Hz. Maximum output impedance is 100 Ω with a bias output voltage of 10 VDC. The grounding is base isolated.

Environmental Specifications:
Operates within a temperature range of -50 to 120°C. Vibration limit is 500 g peak and shock limit is 5,000 g peak. Electromagnetic sensitivity is equivalent to 100 µg/gauss, and base strain sensitivity is 0.005 g/µstrain.

Physical Specifications:
The sensing element design is PZT, compression, with a weight of 28 g. Made from 316L stainless steel, it mounts with a 10-32 tapped hole. The output connector is BNC coaxial, and the mating connector is R2. Recommended cabling is J93.

Connections:
Wilcoxon Research model 732-1D high frequency accelerometer uses a common shell for the function connector pin and power/signal pin.

Features and Benefits:
Features include a wide dynamic range, BNC connector, wide frequency range, and base isolation. Benefits include compatibility with coaxial cable systems, elimination of ground loops, suitability for 1/3 octave data collection, and detection of low and high-speed equipment vibration.
