4-20 mA vs. IEPE vibration sensors for control systems
Outside of the mid-frequency range, an IEPE sensor can be a better option than a standard 4-20 mA sensor. In this setup, an accelerometer or velocity transducer outputs to a vibration transmitter, which conditions the dynamic data into a 4-20 mA signal and sends it to the control system.
Lowpass Filter Circuit Design: Common Mistakes to Avoid
An effective PCB layout manages signal interference, reduces noise, and preserves a system's intended frequency response. Achieving this requires careful separation of signal paths to reduce cross-talk and prevent impedance mismatches and robust grounding practices.
What causes PIM in connectors and how does Amphenol design low PIM ...
PIM is caused by non-linearities in a passive circuit. The main cause of non-linear action in a connector or cable assembly is poor contact junctions, which can be caused by any one of the following: In addition, ferromagnetic materials such as nickel and steel, as well as contamination all contribute to the problem.
