Sensors are used in a variety of consumer and industrial markets from cell phones and tablets to precision detection, distance measurement, identification/image processing and process instrumentation ...
An example is the sensing of a rotary cam position. The oblong shape of the cam dictates use of a sensor able to detect different shapes and sizes. A simple prox sensor merely detects the presence or ...
Jon Gabay, aka Dr. Gizmology, continues his do-it-yourself series. Find previous parts of this series here and here. User interfaces and systems that distribute data acquisition and control can take ...
DW Series round metal inductive proximity sensors with analog outputs are now available from AutomationDirect in 8mm, 12mm, 18mm and 30mm cylindrical sizes. These reliable DC-powered (10-30V or 15-30V ...
Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
Probably the most electronically sensed analog quantity is temperature. An essential factor in most environments and critical in many, temperature is widely sensed in industrial, automotive, building ...
Picking up where we left off in Part 1, we need to explore some methods to mitigate problems caused by unpredictable ground currents.
