Duct Air Flow Sensor

This provides rapid response to the air or gas flow and amount and direction delivering a proportional output voltage.

Duct air flow sensor.

The output can be in mass standard volume or velocity units. Air and most other non condensing gases including corrosive and explosive gases. Free shipping by amazon. Single or multiple airflow elements are factory mounted and pre piped in a casing designed for flanged connection to the duct work.

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. Temperature humidity dew point co voc s pressure and low temperature limit detection. Silicon chip design is created from thin film thermally isolated bridge structure containing both heater and temperature sensing elements. Sensor only digital display.

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. What can we measure. 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.

Totalizers measure the cumulative flow volume. 3 6 out of 5 stars 9. Duct mounted airflow measurement station is easy to install and utilizes an airflow averaging element. Options for hazardous locations intrinsically safe explosion proof are available.
