Duct Air Flow Sensor

Silicon chip design is created from thin film thermally isolated bridge structure containing both heater and temperature sensing elements.

Duct air flow sensor. 3 6 out of 5 stars 9. Ideal for building automation systems bas and hvac applications the design of the airflow sensor allows it to amplify the velocity pressure by a factor of three which in turn allows accurate measurement of low air flow velocities. Flowmeter totalizers display both the flow rate and the cumulative flow volume. Series pafs 1000 ideal for sensing fan flow rates averaging flow sensor is ideal for sensing differential pressure in the inlet section of variable air volume terminal units and fan terminal units.

All airflow sensors operate on heat transfer flow and differential pressure. Duct sensors air belimo offers a broad range of air duct sensors covering all standard measurement values. This provides rapid response to the air or gas flow and amount and direction delivering a proportional output voltage. Standard materials consist of a g90 galvanized casing and 6063 t5 anodized aluminum flow sensors suitable for most hvac applications.

Air flow in cfm q flow velocity in feet per minute v x duct cross sectional area a. Flowmeters measure the rate of flow for a liquid or a gas. 4 2 out of 5 stars 251. Options for hazardous locations intrinsically safe explosion proof are available.

What can we measure. Temperature humidity dew point co voc s pressure and low temperature limit detection. Determining duct air flow in cfm using the bapi pressure sensor application note to calculate air flow in cubic feet per minute cfm determine the flow velocity in feet per minute then multiply this figure by the duct cross sectional area. Rheotherm flow sensing probes for duct gases are easy to install and provide long term service with little or no maintenance.

Remote or duct mounting 0 10 v or 4 20 ma output. Get it as soon as wed sep 30. Air and most other non condensing gases including corrosive and explosive gases. Available in 0 10 v output or 4 20 ma output.

Duct mounted airflow measurement station is easy to install and utilizes an airflow averaging element. Air velocity transmitter coupled with temperature monitoring. Totalizers measure the cumulative flow volume. Free shipping by amazon.

Sensor only digital display. Single or multiple airflow elements are factory mounted and pre piped in a casing designed for flanged connection to the duct work. Comes with optional display to show air velocity and temperature as well as option to choose rs485 modbus.
