Function 
The new OMEGA® PX5200 is a 
compact wet/wet differential pressure 
dP transmitter, ideal for flow and 
tank level applications where 
reliable, low dP measurements are 
required. Equipped with a solid state 
sensor and a 316 Stainless Steel 
isolating diaphragm, the PX5200 
can monitor a wide variety of wet or 
dry media. Available in unidirectional 
ranges from 0 - 4 to 0 - 400 inH2O 
and bi-directional ranges up to 
PX5200
±200 inH2O, the PX5200 operates 
on line (static) pressures up  
to 300 psi.
A rugged aluminum NEMA 4X 
(IP65) enclosure measures only 
65 mm (2.56") in diameter and 
incorporates a backlit LCD display 
for local reading.
The output is a two-wire 
configurable 4 to 20 mA signal that 
can be adjusted to re-range the 
transmitter or “tare” unwanted fluid 
head preloads. In addition, this 
instrument offers flow measurement/

square root extraction, where the 
indicated flow rate and analog signal 
can be displayed. Rangeability for 
zero and span are from -10 to  
110% FS URL (Upper Range Limit). 
This means a 20 inH2O transducer 
can have the zero set between 
-2 inH2O to FS 22 inH2O. Span  
can be set over that range also.  
For example zero could be set for  
2 inH2O and 22 inH2O maximum  
so the output would be 4 mA at  
2 inH2O, midpoint 12 mA would be  
12 inH2O and 20 mA would be  
22 inH2O.
