DPT-2W
Multi-range differential pressure transmitters with 2-wire configuration
DPT-2W series differential pressure transmitters are engineered for building automation in the HVAC/R industry. The DPT-2W measure static and differential pressure and they have a field selectable range.
DPT-2W series devices include:
• 8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper, (see Product Information)
• Pressure measurement in Pa
• 4-20 mA 2-wire current loop
