PSE541 and PSE543 are remote vacuum sensors with a 1 to 5V analog signal output.  The sensor construction optimizes space savings, for tight, constrained spaces.  PSE541 is for a low vacuum (-101 to 0 kPa), while PSE543 is for compound pressure (-100 to 100 kPa).  PSE sensors can monitor any non-corrosive, non-flammable gas.  8 different port options offer tremendous adaptability to various
