Pressure Transmitter Simulator – Working Principles
Every pressure transmitter does the same job: turn pressure into a 4 to 20 mA signal. The difference is the sensing principle: what physical property changes when the diaphragm moves. Pick a sensor type, change the pressure, and watch the sensor, the electrical signal, and the path to the final 4 to 20 mA output.

Pressure Transmitter Simulator
The Pressure Transmitter Simulator is an interactive learning tool that explains how different pressure sensors work and convert pressure into an electrical signal. Explore Bourdon tube, strain gauge, piezoresistive, capacitive, inductive, Hall effect, piezoelectric, resonant, and optical sensing technologies.
Change the applied pressure and process temperature to observe sensor behaviour, signal conditioning, and the standard 4–20 mA output used in industrial instrumentation.
This simulator is ideal for instrumentation engineers, technicians, and students learning pressure measurement, transmitter fundamentals, and process control systems.
Explore the simulator below to understand how pressure transmitters work in power plants, refineries, and other process industries.
