To complement the 2-wire and 3-wire sensor transmitter blogs that Kevin Duke and I have already published on Precision Hub, my next few blog topics will be on 4-wire sensor transmitters. The blogs ...

Industrial temperature sensors are widely used with 4–20mA current-loop transmitters in industrial control and automation. In the current loop the temperature sensor converts a temperature into a ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...
