Our Heritage in Aviation Systems
From 1972 until the late 1990s, our core business was in power failure warning indicators for analog aircraft instrumentation. We have served, and in some cases continue to produce legacy products for the markets and programs listed at right.
Commercial
- Boeing
- Airbus
These rotary solenoid-actuated devices, which are designed to be MIL STD 810 G compliant and have successfully completed independent verification testing, reliably alert pilots to changes in circuit conditions as they occur during flight.
Specified for their compact size, low power consumption and high resultant force, these indicators provide autonomous advance warning of system malfunction and potential unsafe or hazardous conditions.
General Aviation
- Cessna
- Learjet
- Gulfstream
New Uses for Warning Indicator Technology
Indicators have a variety of automatic hazard detection and warning uses in the commercial electronics, industrial automated production line and quality control equipment where accuracy is paramount.
Military
- Black Hawk
- B1-B
- F-14, F-15, F-16, F-18
- A-10
If you have a need for an indicator, consider the failsafe properties of electromechanical rotary solenoids and contact Brandstrom Instruments.
