Yes, you can. Of the various force sensors we make, the ones most suitable for a wind tunnel investigation would be our Dual-Range Force Sensor<\/a> (DFS-BTA<\/nobr>) and Go Direct®<\/sup> Force and Acceleration Sensor<\/a> (GDX-FOR<\/nobr>). If you want to measure more than one force at once (i.e. lift and drag), you will need multiple force sensors.<\/p>\n

In general, you can think of our force sensors as similar to spring scales, but they read force and relay it to a computer or mobile device for graphing and analysis. Some considerations when setting them up to work in a wind tunnel:
\n* Our force sensors may not be sensitive enough, depending on the magnitude of the forces generated. For instance, the Dual-Range Force Sensor’s most sensitive range is 10 Newtons. You should give some thought to the magnitude of the forces you would be measuring.
\n* If the size of the air foils and wind speeds you are investigating generate extremely small forces (relative to the force sensor measurement range), you may need to use a lever system to increase the force or you may need a more sensitive probe than ours.<\/p>\n

Our Go Direct®<\/sup> Force and Acceleration Sensor<\/a> (GDX-FOR<\/nobr>) can connect via Bluetooth or USB to a device running our Graphical Analysis app<\/a>, Graphical Analysis Pro<\/a>, LabQuest 2<\/a> (LABQ2<\/nobr>), or LabQuest 3<\/a> (LABQ3<\/nobr>). The Dual-Range Force Sensor<\/a> (DFS-BTA<\/nobr>) requires an interface [such as a LabQuest Stream<\/a> (LQ-STREAM<\/nobr>), LabQuest 2, or LabQuest 3] to connect to a computer or mobile device.<\/p>\n
