Wind Tunnel Balance 2.0

KineOptics has recently developed this simple cost effective Wind Tunnel Balance system. This component balance system will accurately measure small forces, typically lift, drag, and pitch moment, in small wind tunnels and water tunnels.

The KineOptics Wind Tunnel Balance utilizes a very flexible open architecture design in that the basic isolation axis can be configured in multiple axes and with various thickness flexures and load cells suitable to the intended application.

Each Component Balance Axis has a hard stop to prevent overload of the flexures when the load cells are not coupled.

The KineOptics WTB design is manufactured from 300 series stainless steel. It is designed for harsh environments in both wind tunnels and water tunnels. The KineOptics WTB design is difficult to damage if accidently overloaded but care must be taken when the load cells are coupled as they can be overloaded.

KineOptics does have a special design for mounting our Sensotec Model 11 Load Cells. This mounting design incorporates full protection of the small Sensotec 0-250 gram load cell while providing accurate measurement of small forces.

The WTB 2.0 is designed to measure forces in various ranges, depending on the flexure and load cell configuration. The maximum for the WTB 2.0 would be 0-25kg. The lowest forces would be in the 0-250 gram range. This is using our Sensotec 0-250 gram load cell.

The WTB 2.0 is sold on a component level. Each axis can be purchases separately. An axis unit does not include any load cells or load cell attachment hardware. We can design and supply mounting hardware for your particular load cell requirements for additional costs.

We also sell an Angle Kit to join the two units together to form a "Lift / Drag" measuring assembly. This is the conventional arrangement. There are other arrangements possible such as a three unit assembly for lift, drag, and pitch moment..

The WTB 2.0 is a semi-stock item. Depending on the configuration, shipping will take 2 to 6 weeks. E-mail or call for more information.

The WTB design is modular so parts are replaceable if damaged by an accident. Also, different gauge flexures can be ordered to allow various ranges of measurement.

KineOptics can supply larger models to meet your specific requirements. Please contact us regarding this or any other matter.
