Duct Differential Pressure Transmitter, 0-1", 0-2.5", 0-5", 0-10" Selectable
Overview
P7640 Pressure Sensors are designed with field-selectable 4-20 mA, 0-5 Vdc, or 0-10 Vdc output. They switch selectable pressure ranges between 0-1 in. w.c./0-250 Pa or 0-10 in. w.c./0-2500PA depending on the model.
Features
- The P7640A Panel Mount, P7640B Duct Mount and P7640U Universal 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.
- Selectable inches w.c. or Pascal scale.
- Selectable fast or standard response time.
- Duct mount model comes with factory installed duct probe.
- The Universal model comes with attachable duct probe and can be used in either panel or duct mounting application.
