Intrinsically Safe Differential Pressure Transmitter Dwyer Series ISDP

Intrinsically Safe Differential Pressure Transmitter  Dwyer Series ISDP

• The 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.
