Common Questions

• What makes the CE311 different from other accelerometers?

It has built-in electronics that convert charge to current. This means you don’t need an external charge amplifier. The current signal can travel very long distances without quality loss.

• Can I use the CE311 in wet conditions?

Yes, the sensor and protection tube are hermetically welded together. This creates a leak-tight seal that keeps out water, steam, oil, and other liquids.

• What power supply does the CE311 require?

It needs 15 to 28 VDC power. The standby current is between 5.5 and 7.5 mA. This is standard industrial power that is easy to provide.

• How accurate is the CE311 accelerometer?

It has ±1% linearity across its full measurement range. The sensitivity stays within ±5% from -40°C to +125°C. It maintains <3% transverse sensitivity.

• Is the CE311 ready to use out of the box?

Yes, it comes factory calibrated at 120 Hz and 5 g peak. No additional calibration is needed. You can mount it and start measuring immediately.
