What is Vibration Monitoring?
Since the invention of the wheel Vibration has been an issue. Once wheels were mounted to an axle or shaft, out of roundness and unbalance became prime concerns. As the industrial revolution arrived |
Tech Note 115: Shunt Resistors
Occasionally a customer will ask us how to interface one of our Transmitters with a 4-20 mA
output to a DC Input Field IO Card. What is important to understand is that even
