Pressure Sensor Simulator – Interactive Pressure Measurement
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 (or liquid, or gas) responds. Pick one of 19 sensor types, change the pressure, and watch the sensor, the electrical signal, and the path to the final 4 to 20 mA output.

Frequently Asked Questions
What is a pressure sensor simulator?
A pressure sensor simulator is an interactive learning tool that demonstrates how different sensing technologies respond to applied pressure and generate measurable signals.
What is the difference between a pressure sensor and a pressure transmitter?
A pressure sensor detects pressure and produces a physical or electrical response. A pressure transmitter processes that response and provides a standardized output, commonly 4–20 mA in industrial applications.
What is a strain gauge pressure sensor?
A strain gauge pressure sensor measures the deformation of a diaphragm. This deformation changes the resistance of bonded strain gauges, producing a small electrical signal that can be amplified and converted into a pressure reading.
Why is temperature compensation important?
Temperature can affect sensor resistance, sensitivity, and mechanical properties. Compensation reduces temperature-related measurement errors.
Who can use this simulator?
Instrumentation engineers, students, technicians, and process-control professionals can use it to understand sensor principles and compare measurement technologies.
