What is a 4-20 mA Sensor?

 

Travis Bottalico, CTO & VP Engineering for Avimesa, runs through what a 4-20mA industrial sensor is, and how a current loop is used to output data.

Avimesa offers hardware, device cloud, and IoT hosting for developing and deploying industrial IoT solutions. Our wireless boards connect with up to seven 4-20mA sensors, sending data to our device cloud which can be used for monitoring and remote actuation.
