The Dwyer ISDP Differential Pressure Transmitter provides a 4-20 mA process output, a robust NEMA 4X enclosure, plus a large LCD display that can be programmed to read in pressure, velocity or flow. The ISDP offers simplified programming via a Menu key that enables the user to select security level; English or Metric engineering units; pressure, velocity or flow operation; K-factor for use with various Pitot tubes and flow sensors; circular or rectangular duct size for volumetric flow operation plus many more.

The Dwyer ISDP Differential Pressure Transmitter is powered on its two wire loop with 10-35 VDC via its integral M-12 four pin male connector. The ISDP provides a 0.5% full scale accuracy on ranges from 0.25" w.c. to 100" w.c. as well as bi-directional models up to 10" w.c. These features make the Series ISDP Differential Pressure Transmitter the ideal instrument for monitoring pressures or air flows in hazardous zones having Class I Div I Groups A, B, C, D; Class II Div I Groups E, F, G; Class III Div I ratings.
