4203 Series Accelerometer

Description: The Model 4203 is a triaxial motorsport accelerometer designed for harsh installations. The rugged, gas damped accelerometer is ideally tailored for motorsport applications and road vehicle testing. The model 4203 features an 8-pole low-pass filter to ensure no high frequency engine noise will leak into the passband. A heavy-duty shielded cable and an EMI/RFI module protects the accelerometer from the harsh operating environment. Available in ranges from ±6g to ±50g, the model 4203 will provide reliable measurements from -40°C to 85°C.

Features:

• Triaxial Motorsport Accelerometer
• Critically Gas Damped
• 8-16 Vdc Excitation
• ±6g to ±50g Dynamic Range
• Built-in 8 pole, low pass filter
• EMI/RFI Protection

• Over shock protection to ±5000g
• High Accuracy Temp Compensation
