I'm trying to figure out a way to deal with a ground loop problem I have at home, this is 60hz mains hum that comes out of speakers, even when nothing is connected to the device besides power cable. I ...

The days when converter manufacturers would have little option but to rely on the expertise of power-module specialists to design filters, optimize the control loop, and provide the result, have given ...

Loop-powered transmitters have progressed from purely analog signal conditioners to highly flexible smart transmitters, but the chosen design approach still depends on a system’s performance, ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

The ProSense LPM1 series of loop panel meters offers a simple, low cost digital display of an analog 4-20mA signal. Models are available for mounting in a standard 1/8 DIN size panel cut-out with ...

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 ...

Loop powered particulate transmitter and filter leak/emissions detector for baghouses, cartridge dust collectors and cyclones provides simple 2-wire installation and single piece mounting. Heavy ...
