  • DPT200 High One Side Overload Differential Pressure Sensor - DP transmitter for measuring pressure difference between two pressure points which can tolerate up a very high overload pressure independently on either the positive or negative side port or both together at the same time.
  • Low Differential Pressure Transmitters DPS300 User Switchable Pressure Range, Volts or Current Output Low DP Sensor - The DPS 300 is a low range HVAC differential pressure sensor. The lowest possible pressure range is 0...100 pascals. 2 or 3 switchable pressure ranges, plus volts or current output are included with most standard configurations.

User Guide

This differential pressure flow transmitter square root extraction 4 to 20 milliamp current output calculator provides a way to determine the flow output reading from the pressure drop measured across an orifice plate and the differential pressure transmitter range. A conversion scale graphic for each differential pressure and SqRt 4-20mA flow output range combination entered is also displayed below the calculated values.

Formula

This dp flow transmitter output calculator uses the following formula to calculate the output over a SqRt 4-20mA range:

Linear mA out = 4 + (16 x ((Rdg – Low Limit) / (High Limit – Low Limit)))

Parameters

Unit

Enter the unit used for measuring differential pressure, e.g. mbar, psi, kPa, inH2O etc…

Reading

This is the differential pressure measured by the dp flow transmitter that you wish to convert to a square root extraction 4 to 20 milliamp current output reading.

Low Limit

Enter the lowest pressure that the dp flow transmitter will measure. For example zero would be a typical value for most dp flow transmitters, but you can also add negative (-) or positive (+) values as well. Please enter the value in the same pressure units as specified for all other input values.

High Limit

Enter the maximum differential pressure that the dp flow transmitter will measure.

SqRt Output (mA)

This is the expected ideal dp flow transmitter current output signal in milliamps for theĀ  pressure drop specified.
