Unveiling the LCF-501-R!

The LCF-501 series of Force-balance accelerometers were developed as a transparent counterpart to the LCA-165, possessing the same range options, power requirements and form factor; additionally, the 501 series possesses improved performance due to the designs of the new standardized force-balance module: the J-301. This torquer type makes use of taut-band torsional suspension, rather than…

How to Reduce Noise Interference in Sensor Readings

Precision inertial sensors are so sensitive that even noise waves can be detected as vibration. For many applications, noise is inevitable, but noise interference in the sensor’s readings is unacceptable. This post explains what causes noise disruption and how it can be prevented. What Causes Noise Interference for Sensors Loud machinery within industrial applications can…
