Compound range pressure transmitters for measuring plus and minus pressures using the same device. Compound range transmittters are calibrated with the most negative reading at 4mA and the most positive reading at 20 mA.
Since the same sensing diaphragm is used to measure both the negative and the positive pressure, there is a limit to how great the ratio between positive and negative pressure can be, before the lower range of the two becomes too inaccurate. In the case of a -1 to 10 bar (-15 to +300 psi range which is accurate to 0.25%, will be accurate to only 2.5% over the vacuum range.
Gauge reference pressure transmitters can be configured to measure from -1bar (-15psi) which is approximately zero vacuum up to a positive pressure such +2 bar (+60psi). For ranges below 1 bar (15psi) the compounds range is typically bidirectionally symmetric such as -500 to +500 mbar, but it is also possible to provide ranges such as -200 to +500 mbar if required.
