How thermal stability affects the accuracy of non-contact displacement sensors

In non-contact displacement measurement applications, engineers often overlook the effects of temperature variations on the measurement accuracy of the sensor. It is therefore critical to check supplier datasheets, says Chris Jones



Comparing blue and red laser triangulation sensors

Although red laser triangulation displacement sensors have been in use for more than 20 years, blue laser versions are also now available. Before selecting which colour to use, it is important to understand which type performs best on which target materials, says Chris Jones
