PSE530 and 532 are remote pressure sensors with a 1 to 5V analog signal output.  530 is for a standard pneumatic system's pressure range, while the 532 model is for low pressure.  PSE sensors measure pressure of any non-corrosive, non-flammable gas.  An accuracy of ±2% of the full scale rated pressure range is suitable for general purpose applications.  The cable is replaceable, with a locking
