Current to Pressure Measurement Trainer
Product Code : EL-MAILE-10805
Current to Pressure Measurement Trainer (code EL-MAILE-10805) is a self-contained I to P trainer for showing how a 4 to 20 mA current signal is converted into a 3 to 15 PSI pneumatic output. The converter is fitted on a base with a 30 PSI Bourdon gauge on its input side and another on its output side, a current source with a 3½ digit LED display supplies the signal, and an air regulator with filter, tubing and cable are included.

What Is the Current to Pressure Measurement Trainer Used For?
Current-to-pressure converters link electronic controllers, which send 4 to 20 mA signals, to pneumatic valves and actuators that are worked by air pressure, so they are a common item in process plant instrumentation. With the trainer, students set the current from the source with the potentiometer, read it on the LED display and watch the output gauge move through the 3 to 15 PSI span while the input-side gauge shows the supply. Plotting output pressure against input current shows the conversion characteristic, and the test points on the schematic let the signal path be traced. Compressed air comes from a standard compressor, which can be supplied as an option.
What to Specify When Ordering
- Quantity — the number of trainers required.
- Air compressor — whether the optional air compressor is to be supplied.
- Power supply — the 230 V, 50 Hz or 230 V, 60 Hz single-phase version.
Frequently Asked Questions
What signal conversion does the trainer demonstrate?
It demonstrates the conversion of a 4 to 20 mA current input into a 3 to 15 PSI pneumatic output, the signal ranges used between electronic controllers and pneumatic final control elements.
Does the trainer need compressed air?
Yes. It needs a constant air supply from a standard compressor, given as 30 to 80 PSI continuous. An air regulator with filter is included, and an air compressor can be supplied as an option at extra cost.
How are the input and output pressures shown?
Two 4 inch Bourdon gauges of 30 PSI range are fitted, one on the input side of the converter and one on its output, so both pressures can be read during the exercise.
What is included with the trainer?
The system is self-contained and comes with an air regulator with filter and the necessary tubing and cable. The air compressor is an optional extra at additional cost.
How does the enclosure help in teaching?
The instrument sits in a tapered fibreglass box with all necessary test points brought out on a schematic of the circuit, so students can follow how the current source and converter work.
What are the power needs, size and weight?
It needs a 230 V, single-phase supply of 50 Hz or 60 Hz, measures 500 × 400 × 300 mm and weighs approx. 22 kg.
