4–20 mA Telemetry System

Current telemetry systems are used where the industrial measuring instrument produces a current output varied by means of an adjustable resistance .

The experimental setup helps to understand & use of 4–20 mA transmitter and receiver.

The set up contains :

• Current Transmitter Trainer :

The single board trainer helps to study current transmitter for 2, 3 and 4 wire system. The trainer contains :

1. IC regulated power supply.
2. Current transmitter.
3. Provision for zero and span adjustment facilities.

• Current Receiver Trainer :

The single board trainer helps to study current to voltage receiver. The trainer contains :

1. IC regulated power supply.
2. Digital voltmeter and milliammeter
3. Current to Voltage converter.
4. Provision for zero and span adjustment facilities.

• Oven 200 Degree Centigrade.
• RTD & Thermocouple.
• Oven Controller with Temperature indicator.
