Current To Pressure Measurement Trainer Manufacturer,Supplier and Exporter in India
Product Code : EL-MLLE-9169
Jlab Export is a leading Current To Pressure Measurement Trainer Manufacturer,and suppliers in India
This trainer shows how an I to P converter turns an electrical current signal into an air pressure signal. The converter is fitted on a base and driven by a current source with a digital display. One pressure gauge reads the supply air at its input and a second reads the output pressure. It needs a constant 20 psi air supply from a standard compressor.

I to P Calibration Practicals
The main exercise is a calibration check. Students set the current source to a series of values, first rising and then falling, and read the output gauge at each point. Plotting output pressure against input current shows whether the converter is linear and whether the rising and falling readings agree. Any gap between the two curves is hysteresis. On a converter with zero and span screws, zero is corrected first, then span, and the check is repeated.
For a true calibration the output gauge should itself be compared with a standard, such as a gauge proven on the Dead Weight Pressure Gauge Tester. The reverse conversion is covered by the Pressure To Current Measurement Trainer, so the pair shows the signal changes at both ends of a pneumatic loop. Air can come from a workshop unit such as the Air Compressor, held at a steady 20 psi.
Frequently Asked Questions
What does an I to P converter do?
It takes a current signal from a controller and gives out a matching air pressure. That air signal can then work a pneumatic actuator, such as the diaphragm on a control valve, which an electrical signal cannot move directly.
What air supply does the trainer need?
A constant supply at 20 psi, about 1.4 bar, from a standard compressor. Keep it steady, because a falling or unsteady supply can upset the output readings taken during calibration.
Why are there two pressure gauges?
The input gauge shows the supply air reaching the converter, so students can confirm it is steady before they start. The output gauge shows the converted signal, which is the reading recorded against each current setting.
What is the difference between zero and span?
Zero is the output at the lowest input current. Span is the change in output between the lowest and the highest current. A zero error shifts every reading by the same amount, while a span error grows as the current rises.
Does it need a separate current meter?
No. The current source has its own digital display, so the input current is read there while the output pressure is read on the gauge.
