Introduction
GXPS540 Wind Pressure Differential Pressure Transmitter adopts
high-precision, high stability diaphragm and is assembled by stress
isolation technics. By strict precision temperature compensation
and signal amplification, transfer micro differential pressure, air
pressure, flow and other parameters to reliable 4~20mA or 1~5V
signal output.
