Arduino: Connecting Industrial 4-20mA Sensors – Accurate Level Monitoring! 🌊📊
Want to integrate industrial sensors into your Arduino projects? In this video, we'll show you how to connect and calibrate a 4-20mA hydrostatic level sensor to an Arduino and other controllers! [00:00] This is the key to creating reliable monitoring systems for any application!
What you'll learn in this detailed guide:
Industrial sensor standards: Why the 4-20mA current loop is the most popular standard for sensors and how it's resistant to interference and cable lengths [00:27].
Two-Wire Circuit: How to connect a sensor with just two wires, simplifying installation [01:18].
Sensor Operation: Understand how a 4-20mA sensor works as a variable resistor controlled by an internal current regulator [01:29].
Arduino Wiring Diagram: A simple and effective circuit for measuring a 4-20mA signal using an Arduino analog input, including calculating the optimal resistance (Rx) for converting current to voltage [02:07].
Calibration Process: A step-by-step demonstration of calibrating a system using a lab power supply to emulate a sensor signal [04:03].
Scaling Formula: How to convert raw analog input values into meaningful physical units (e.g., meters of water column) using floating point [08:08].
Real-World Application: See how a real industrial hydrostatic level sensor (PTL 110) works with an Arduino Nano to simulate water level changes [11:01].
This video is an indispensable resource for anyone wanting to work with industrial sensors and create high-precision monitoring systems. Ideal for monitoring liquid levels, pressure, and other parameters!
