Linear to Square Root Extraction
In Linear to Square Root Conversion, Relationship is non-linear there is a greater change in flow at low pressures compared to higher ones.
Formulas
Instrumentation control engineering formulas used in industrial control systems and field instruments like 4-20mA and 3-15 PSI conversions.
Level Calculation with Remote Seals
Diaphragm seals for tanks under Vacuum The transmitter must be mounted level with or below the lowest tap to ensure positive pressure at the transmitter.
Calculate Temperature Coefficient of RTD
RTD’s are based on the principle that the resistance of a metal increases with temperature. The temperature coefficient of resistance (TCR)
