Troubleshooting a 4-20mA Current loop

S Bharadwaj Reddy
The basic layout of every 4-20mA loop consists of a power supply, a transmitter, and passive loop devices. The supply produces the energy to run the loop. The transmitter controls

Why 4-20mA Standard is so popular ?

S Bharadwaj Reddy
4-20mA Standard 4-20mA has an inherent ‘live zero’. Zero engineering units is 4.0mA, not 0.0mA. 0.0mA indicates an open circuit, a failure or a fault mode like cut wires or

Why Use a Current Loop?

S Bharadwaj Reddy
A Little Bit of History Before the advent of electronic circuitry, process control was a wholly mechanical endeavor. Facilities used pneumatic control signals where controllers were powered by varying pressures

Basics of 4-20mA Current Loop

S Bharadwaj Reddy
The 4-20 mA current loop is a very robust sensor signaling standard.  Current loops are ideal for data transmission because of their inherent insensitivity to electrical noise. In a 4-20
