Three models of the PTP accept either a 3 to 15, 3 to 30, or 0 to minus 7.5 psig pneumatic pressure input and convert it to one of four proportional analog output ranges of 1-5, 2-10, 3-15 VDC or 4-20 mA which are jumper shunt selectable. PTP is a positive current output device that is fully temperature compensated. A plugged gauge port is provided in the aluminum manifold for local mechanical indication, if required. The PTP is designed to fit a 2.25" (provided) or 3.25" snaptrack and will accept standard 1/4" O.D. plastic tubing.  The PTP is covered by ACI's Two (2) Year Limited Warranty.
