AC STAG PS-04 MAX pressure sensor – LPG/CNG pressure, vacuum and temperature sensor – up to 5.5 bar – E8 approved – replaces PS-04 PLUS
AC STAG PS-04 MAX: the high-performance pressure sensor for modern LPG and CNG conversions
The AC STAG PS-04 MAX represents the latest generation of pressure sensors for LPG (Autogas) and CNG gas injection systems. Developed to overcome the limitations of its predecessor PS-04 PLUS, the PS-04 MAX pressure sensor offers an extended measurement range up to 5.5 bar for both pressure and vacuum, making it ideal for modern engines including turbocharged, direct injection, and diesel engines converted to LPG/CNG.
Where the previous PS-04 PLUS sensor reached a maximum of 4 bar, the STAG PS04 MAX sensor easily handles higher boost pressures, preventing unnecessary fuel switchovers to petrol during peak loads on turbocharged engines.

Why choose the AC STAG PS-04 MAX?
With the PS-04 MAX LPG sensor, STAG delivers the perfect solution to a well-known problem in LPG and CNG conversions. In modern turbocharged engines, standard sensors often reached their limit, causing unnecessary switching back to petrol. Thanks to the 5.5 bar high-pressure gas sensor, this issue is completely eliminated.
The LPG MAP sensor features highly precise yet extremely robust sensing elements, specifically designed to resist gas contamination. This ensures stable, accurate and durable measurements even after many years of use.
