Troubleshooting a 4-20mA Current loop
The basic layout of every 4-20mA loop consists of a power supply, a transmitter, and passive loop devices. The supply

Why 4-20 mA Standard is so popular ?
4-20 mA Standard 4-20mA has an inherent ‘live zero’. Zero engineering units is 4.0mA, not 0.0mA. 0.0mA indicates an open
