Interactive pressure measurement trainer — 0–100 PSI — LC = 2 PSI
A pressure gauge measures the pressure of gases or liquids in pipelines, tanks, cylinders, and hydraulic systems. This free online simulator covers 0–100 PSI with 2 PSI least count and a dual scale showing PSI, BAR and kPa simultaneously — essential for students in pneumatics, hydraulics, and fluid power training.
Step 1: Identify the scale units (PSI, BAR, or kPa). Step 2: Count the number of divisions between major marks to find the value of each small division. For this simulator each small division = 2 PSI. Step 3: Read the needle position — if it falls between marks, interpolate to the nearest graduation.
Key conversions to memorise: 1 BAR = 14.504 PSI, 1 BAR = 100 kPa, 1 PSI ≈ 6.895 kPa. The dual-scale gauge in this simulator displays all three simultaneously, reinforcing unit recognition — a critical competency in pneumatics, HVAC, automotive, and process instrumentation training.
Common types include: Bourdon tube gauges (most common for industrial applications), diaphragm gauges (for low pressures and corrosive media), and digital pressure gauges (for high-accuracy electronic measurement). This simulator models the standard Bourdon-type analogue gauge.
Designed for pneumatics and hydraulics students, automotive technology trainees, HVAC technicians in training, process plant operators, and any TVET learner who needs to demonstrate pressure gauge reading competency.
