4-20 mA transmitter current output can be converted to the voltage within a specified range, from 0 to a maximal amplitude Vmax,
For any unit conversion on any PLC, you can use four function math with the following for PLC Analog Input
Sensor Scaling – Converting Current and Voltage Inputs To Engineering Units Such As psi, Deg C, m3/hr etc… Sensor Scaling
In Linear to Square Root Conversion, Relationship is non-linear there is a greater change in flow at low pressures compared to higher ones.
RTD’s are based on the principle that the resistance of a metal increases with temperature. The temperature coefficient of resistance (TCR)
The amount of psi can also be calculated from the amount of the milliamp signal, or one can calculate the amount of the milliamp
Flow Coefficient Kv Definition Kv-value: Amount of flow (m3/hour) of water of 20°C in a valve with a pressure loss
An electronic transmitter with an output of 4 – 20 mA is calibrated for a pressure range of 7 –
A pH transmitter has a calibrated range of 4 pH to 10 pH, with a 4-20 mA output signal. Calculate
