To complement the 2-wire and 3-wire sensor transmitter blogs that Kevin Duke and I have already published on Precision Hub, my next few blog topics will be on 4-wire sensor transmitters. The blogs ...
The MLX90323 is a sensor interface IC with 4-20 mA current loop output for sensors wired in bridge or differential configurations.The IC converts small changes of output voltage of full Wheatstone ...
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 ...
Texas Instruments (TI) today introduced the industry's first magnetic sensing integrated circuit (IC) with a fully integrated fluxgate sensor and compensation coil driver, along with all the required ...
When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...
IEEE P1451.4 defines a sensor with embedded TEDS and a mixed-mode, analog and digital interface. Most sensors put out some sort of analog signal -- a voltage, current, or resistance, that varies in a ...
Allegro MicroSystems today announced three ICs: two analogue current sensors and a motor driver for fans. The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly ...
The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...
The dominant standard interface, or output, for these sensors is an analog signal—typically voltage, current, or resistance—which varies in proportion to the physical parameter. Instrumentation ...
