This sensor measures the temperature, which is subsequently converted into 4–20mA current over the loop current source. Temperature variation changes the resistance of the RTD. When RTD is used in a ...

The temperature compensation sensor senses the ambient, or surrounding, air temperature and forces the velocity sensor to stay at a constant "overheat" above the ambient. The sensors form two opposite ...

A Wheatstone bridge is one of those handy circuits that has plenty of uses in both AC and DC measurements. ... RTD, sensing, sensors, temperature probe, wheatstone bridge.

Figure 1 Feedback from the soldering iron's PTC temperature sensor controls the on-time vs the off-time of M2 to regulate the iron's temperature to the selected value. Most parts are not critical. A ...
