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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDuct-mount configuration with factory-installed duct probe for simplified installation\u003c\/li\u003e\n\u003cli\u003eSelectable pressure scale: inches water column (inches w.c.) or Pascals\u003c\/li\u003e\n\u003cli\u003eSelectable fast or standard response time to match system control requirements\u003c\/li\u003e\n\u003cli\u003eDesigned for extremely low differential pressure measurement\u003c\/li\u003e\n\u003cli\u003eNo display model suited for installations using external building automation or BMS readout\u003c\/li\u003e\n\u003cli\u003eSuitable for clean rooms, hospitals, fume hoods, and computer rooms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style differential pressure transmitter for duct-mount applications in commercial and institutional HVAC and building automation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Duct Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Scale\u003c\/strong\u003e: Selectable inches w.c. or Pascals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time\u003c\/strong\u003e: Selectable fast or standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Accessories\u003c\/strong\u003e: Factory-installed duct probe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: p7640b1032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51468599656754,"sku":"P7640B1032","price":303.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/P7640B1032.jpg?v=1783918623","url":"https:\/\/voomisupply.com\/products\/honeywell-p7640b1032-differential-pressure-sensor-duct","provider":"Voomi Supply","version":"1.0","type":"link"}
