How many types of 4-20 mA type transmitters?

Question

Accepted Answer

There are several types of 4-20 mA type transmitters used in automation engineering.

Some common types include pressure transmitters, temperature transmitters, level transmitters, and flow transmitters.
Each type of transmitter is designed to measure a specific parameter and convert it into a 4-20 mA current signal.
For example, a pressure transmitter measures the pressure of a fluid or gas and converts it into a 4-20 mA signal.
Similarly, a temperature transmitter measures the temperature of a process and converts it into a 4-20 mA signal.
Other types of transmitters include humidity transmitters, pH transmitters, and vibration transmitters.
The 4-20 mA signal is widely used in automation systems for its simplicity, reliability, and compatibility with analog input modules.

Accepted Answer

There are 2 types of 4-20 mA type transmitters
1. 2 wire in which 2 wires are used for operating the transmitter and also used to get 4-20 mA singal from transmitter.
2. 4 wire in which 2 wires are used for operating the transmitter and another 2 are used to get 4-20 mA signal from transmitter.
