Columbia Research Force Balance Triaxial Accelerometer SA-302BHC
Product Description
The Columbia Research SA-302BHC is a high-accuracy force balance triaxial accelerometer designed for precise measurement of acceleration forces in demanding laboratory and industrial environments. Ideal for applications in biotechnology, biomechanical engineering, and molecular diagnostics involving vibration and shock analysis, it delivers reliable multi-axis data critical for bioprocessing and biomanufacturing workflows.
- Measurement Range: ±1 G to ±35 G enables versatility across low- to high-acceleration environments.
- Output Voltage: Stable +5 VDC into 100 kΩ load supports robust signal acquisition.
- Excitation Voltage: Operates on +24 to +32 VDC with a max current of 50 mA.
- Output Impedance: < 5000 Ohms ensures low signal loss.
- Alignment & Sensitivity:
- Sensitive axis alignment better than 0.5°
- Scale factor tolerance ±1%, and temperature coefficient of 0.02% per °C
- Zero bias of +0.01 VDC with null temperature sensitivity of 0.0006% F.R./°C
- Dynamic Performance:
- Natural frequency ≥100 Hz suitable for high-fidelity vibration capture
- Damping of 0.7 ±0.1 at 25 °C, adaptable over temperature range
- Non-linearity and hysteresis both ≤0.05% F.R. for precise repeatability
- Environmental Ratings:
- Operating temperatures from -55 °C to +85 °C
- Storage up to -60 °C to +100 °C
- Vibration survival at 15 G RMS (2–2000 Hz) and shock tolerance up to 100 G over 11 ms
- Ambient pressure range from vacuum (-1,000 ft altitude) to 5 atmospheres and up to 88,000 ft altitude, with 95% relative humidity tolerance.
- Physical Characteristics:
- Weight: 624 grams (22 oz) with compact dimensions of 11.3 cm (L) × 8.0 cm (W) × 5.7 cm (H)
- Robust aluminum black anodized casing per MIL-A-8625 Type II Class 2 for durability in harsh laboratory and industrial settings
- Environmental sealing and metal photo labeling per MIL-STD-130K for traceability and compliance
- Connectivity:
- Standard MS3112E12-10P electrical connector with optional mating PT06A-12-10S(SR) connector compatibility
The SA-302BHC accelerometer is widely used in biotechnological research, synthetic biology instrumentation, and clinical diagnostics where precise measurement of multi-axis dynamic forces is critical. Its environmental robustness and electrical stability make it essential for live-cell imaging platforms, neuroengineering vibration studies, and biopharmaceutical production pipeline monitoring.
