Available in 0 10 v output or 4 20 ma output.

Duct air flow sensor.

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. Air and most other non condensing gases including corrosive and explosive gases. Options for hazardous locations intrinsically safe explosion proof are available. Sensor only digital display.

The amp series ampliflow air velocity sensor is designed to measure air flow velocity in hvac duct systems. Duct sensors air belimo offers a broad range of air duct sensors covering all standard measurement values. 3 6 out of 5 stars 9. Comes with optional display to show air velocity and temperature as well as option to choose rs485 modbus.

The output can be in mass standard volume or velocity units. Tjernlund ps1503 duct airstat pressure switch. Free shipping by amazon. Standard materials consist of a g90 galvanized casing and 6063 t5 anodized aluminum flow sensors suitable for most hvac applications.

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. 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. Single or multiple airflow elements are factory mounted and pre piped in a casing designed for flanged connection to the duct work. This provides rapid response to the air or gas flow and amount and direction delivering a proportional output voltage.

Remote or duct mounting 0 10 v or 4 20 ma output. What can we measure. Air velocity transmitter coupled with temperature monitoring. Rheotherm flow sensing probes for duct gases are easy to install and provide long term service with little or no maintenance.
