What is a Pressure Sensor? In this video you are going to learn what a pressure sensor is and how it works in an easy-to-follow format. In a nutshell, a pressure sensor converts the pressure to a small electrical signal that is transmitted and displayed. These are also commonly called pressure transmitters because of this. Two common signals that are used is a 4 to 20 milliamps signal and a 0 to 5 Volts signal. ▶ Check out the full blog post over at https://realpars.com/pressure-sensor/ #PLC #El
