The Barton Model 199 differential pressure unit is a forged-steel bellows-type DP sensing element built to feed a Barton chart recorder or gauge with a stable, repeatable differential pressure signal. A 316 stainless steel bellows and Viton O-rings handle the process media, an Inconel spring sets the calibrated span, and the assembly is filled with hydrocarbon oil for consistent response. The standard 2-inch pipe slip-on mounting and 1/2 inch NPT top by 1/4 inch NPT DP connection match Barton's existing recorder and static pressure assembly hardware, so it drops into an existing installation without rework. The 199N variant is built to NACE-compliant material requirements for sour service.

Frequently Asked Questions
What differential pressure range does the 199N(0-400” WC) SWP :2500PSI cover?
0-400" WC, with a safe working pressure of 2500 PSI.
What is a Barton differential pressure unit used for?
It's the bellows-type sensing element that feeds a Barton chart recorder or gauge a stable, repeatable differential pressure signal, commonly used for flow or level measurement via orifice plate or similar primary element.
What materials are wetted by the process?
A 316 stainless steel bellows and Viton O-rings, filled with hydrocarbon oil, inside a forged steel housing.
Is this compatible with my existing Barton recorder?
It uses Barton's standard 2 inch pipe slip-on mounting and 1/2 inch NPT top by 1/4 inch NPT DP connection; confirm your existing hardware matches, or send us your current unit's details and we'll verify.
What's the difference between the 199 and 199N models?
The 199N is built to NACE-compliant material requirements for sour (H2S) service; the standard 199 is for commercial, non-sour applications.
Should I choose the 199N(0-400” WC) SWP :2500PSI or the 199N(0-200” WC) SWP :2000PSI?
Compare the headline specifications above against your process requirements. The 199N(0-200” WC) SWP :2000PSI differs in rating from the 199N(0-400” WC) SWP :2500PSI; contact our team and we'll confirm the exact match for your application.
