  • Answer:

    This logger can accept inputs from up to three pressure transducers.  It is designed to be used with pressure transducers that measure in PSIG and connect via an NTP threaded connection.    Typically a differential pressure gauge or logger uses two inputs and gives the variance between the two.  This will just give you the data for each input in PSIG.
