HONEYWELL P7640B1008 Differential Pressure Transmitter, 0-1.0, 0-0.5, 0-0.25, or 0-0.1 inches w.c., uni- or bi-directional, duct mount, with display. The P7640 Pressure Sensors are designed with field-selectable 4-20 mA, 0-5 Vdc, or 0-10 Vdc output. The four pressure range options offered on each model fall between 0 and 1 inches water column (in. w.c.) or 0-10 in. w.c., depending on the model. Pressure ranges can be set for either uni-directional (e.g. 0 to 1.0 in. w.c.) or bi-directional (e.g. -1.0 to 1.0 in. w.c.)
• The P7640A Panel Mount and P7640B Duct Mount Differential Pressure Transmitters provide reliable, accurate measurement and control.
• Proper applications include measurement of extremely low pressure applications such as: building/room pressure, air flow, variable air volume, filter status, and duct pressure.
• They are ideal for clean rooms, hospitals, fume hoods, and computer rooms.
