Pressure transducer millivolts to pressure

1Parameters

Editable starting values, not standards or manufacturer recommendations. Check the values for your material or equipment.

How it works

In Numloom: “Pressure sensor voltage” → “Pressure after linear calibration”.

mV → bar

This page shows the formula and parameters. The calculation runs in Numloom.

Assumptions and limits

Calculation basis: “Pressure sensor voltage” (mV) → “Pressure after linear calibration” (bar). Use the parameters shown for this particular operation.

Use the sensor's measured zero and span under the actual excitation conditions. Millivolts and millivolts per volt are not interchangeable; this linear model does not establish sensor accuracy.

Enter a non-negative value in the app.

Coefficient sources

Initial settings: Signal at the lower calibration point = 0 mV (demonstration value); Difference between upper and lower signals = 10 mV (demonstration value); Difference between output values = 10 bar (example in the original task description); Output at the lower calibration point = 0 bar (demonstration value).

These starting values are not a standard, calibration certificate or manufacturer recommendation. Replace them with values measured for your process or specified for your product.
