The Novato reference design (MAXREFDES16#) is a 16-bit, high-accuracy, loop-powered temperature transducer that transmits temperature information from a remote object to the central control unit over ...
The top model high flow NEXT offers in addition to the flow sensor measurement of the coolant quality by measuring the electrical conductivity. In addition, the water temperature is precisely measured ...
Using an analog temperature sensor, an op amp, a transistor, and a low-dropout linear regulator, this circuit provides a 4-to-20-mA output over a 3.75- to 28-V compliance range (see the figure).
