How To Measure Relay Contact Resistance
Relay Contact Resistance
Contact resistance is a crucial electrical characteristic. The resistance between the contact terminals determines the Relay's ability to carry current. The contact resistance is subject to change during the life of the Relay. Based on lab investigations and testing, abnormal contact resistance has often been found with the following conditions:
Measurement Sensors: Specular vs Diffuse
Have you ever wondered why some Measurement Sensors can only be used on dull surfaces (e.g. thread depth measurement on a tire), or only on shiny surfaces (e.g. thickness measurement of glass)? In order to fully grasp the concept, some basics about reflection must be covered. Let’s get some background information on reflection.
Temperature Controllers Using Hysteresis
A temperature controller is a device that one can employ to provide a consistent temperature in their process. Panasonic Temperature Controllers have a PID function to calculate an appropriate counter response to fluctuations in the process.
