Answer / manohar chotrani

Negative range of a transmitter is nothing but the range
required to measure the vacuum of any equipment.If the
pressure inside a tank or equipment drops below zero and
goes to negative side then it is measured by the
transmitter.Maximum of 14.7 psi vacuum can be measured at
ideal conditions.For example a transmitter range is
calibrated as -600 to +600 mm of water means the
transmitter will measure negative pressure inside a pipe or
column or tank and give output as 4 mA and at pressure of
600mm(positive )it give 20 mA output
