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 ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

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 ...

Researchers at the University of Arkansas and the University of Michigan have reported the first use of ultra-low power temperature sensors using graphene-based solar cells. The test is the first ...

Electrical engineers at the University of California San Diego have developed a temperature sensor that runs on only 113 picowatts of power -- 628 times lower power than the state of the art and about ...

In a groundbreaking application of graphene technology, the first graphene-based solar cells have been successfully utilized to power temperature sensors. This development, reported on November 12, ...
