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 ...

Industrial temperature sensors are widely used with 4–20mA current-loop transmitters in industrial control and automation. In the current loop the temperature sensor converts a temperature into a ...

Micro-Epsilon has expanded its range of non-contact infrared temperature sensors to include a new programmable, two-wire loop powered version. The new thermoMETER CSmicro 2W sensor is a 4-20mA ...

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).

Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...

The LPU-2428 Loop-Powered Ultrasonic Level Sensors obtain all operating power from the 4-to- 20-mA process loop. An internal microprocessor performs volume, flow, and totalization calculations. The ...
