4.1 4-20mA Current Calculations

Temperature value to current calculation:

Temperature Range Current Output Formula
0 ~50°C 4~20mA I = (t – 0°C) / (50°C) · 16mA + 4mA

 

Pressure value to current calculation:

Pressure Range Current Output Formula
Pmin ~ Pmax psi 4~20mA I = (p – Pmin psi) / (Pmax psi) · 16mA + 4mA
