Series ISDP Intrinsically Safe Differential Pressure Transmitter
For Hazardous Zone Pressure and Flow Applications
The Series 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 Series 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 a Class I Div. I Groups A, B, C, D; Class II Div. I Groups E, F, G; Class III Div. I ratings.

Certificate of Origin
NIST Certificate of Calibration
- ISDP-002 range of 0-0.25 in w.c. Is the accuracy 0.5% for the entire range? We are monitoring values as low as 0.007 in w.c.
- Yes, the 0.5% is a full-scale accuracy at 77°F (25°C) including hysteresis and repeatability (after 1-hour warm-up).
