Honeywell p7640b1032 Differential Pressure Sensor Duct

Product Description

The HONEYWELL p7640b1032 is a duct-mount differential pressure transmitter designed for accurate, reliable measurement and control of extremely low pressure applications in commercial and institutional HVAC systems. The unit ships with a factory-installed duct probe, eliminating field fabrication of the sensing interface. Pressure scale is selectable between inches water column (inches w.c.) and Pascals, and response time can be set to fast or standard depending on system requirements. Licensed HVAC technicians and building automation specialists are the primary installers of this device.

This transmitter is suited for building and room pressure monitoring, air flow measurement, variable air volume (VAV) system control, filter status indication, and duct pressure sensing. Typical installation environments include clean rooms, hospitals, fume hoods, and computer rooms where low-pressure differential measurement is critical to maintaining safe, controlled airspaces. The duct-mount configuration allows direct integration into supply or return ductwork without requiring a separate panel enclosure.

Key Features

• Duct-mount configuration with factory-installed duct probe for simplified installation
• Selectable pressure scale: inches water column (inches w.c.) or Pascals
• Selectable fast or standard response time to match system control requirements
• Designed for extremely low differential pressure measurement
• No display model suited for installations using external building automation or BMS readout
• Suitable for clean rooms, hospitals, fume hoods, and computer rooms

Compatibility

Designed as an OEM-style differential pressure transmitter for duct-mount applications in commercial and institutional HVAC and building automation systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or building automation controls specialist. Shut down the air handling unit and verify zero static pressure in the duct before mounting the probe and making wiring connections. Follow NEC requirements for low-voltage signal wiring and maintain separation from line-voltage conductors. Verify transmitter range and output signal match the requirements of the connected building automation controller before commissioning.
