LM134 makes a good temperature sensor because it has a highly linear output characteristic. Because it is a current output device and is therefore not affected by long wire runs, LM134 is particularly useful in remote sensing applications. LM134 is easy to calibrate. It has good long term stability and can be interfaced directly with …

This circuit is used to allow a 4mA–20mA to power an analog temperature sensor. To provide a 4mA–20mA output over a 3.75V–28V compliance range this circuit uses an op-amp, low-dropout linear regulator, transistor and an analog temperature sensor. It is powered by the loop with the only consequence being a slight offset error because of …

In some industries, to control the some equipments they are use computer-controlled 4-20mA current loop. This current loop is used transmit a signal over a long distance wires. With current loop, the signal will be resistant from noise interference.
To operate this computer-controlled 4 – 20mA we need a single power supply with a range of …
