Non-Moving Parts Instruments For Measurements of:
- CROSSWIND AND HEADWIND
- ATMOSPHERIC PRESSURE
- AIR TEMPERATURE
FIDELITY patented Thermal Anemometers provide long term trouble
free operation under most severe conditions. They withstand shock,
vibration, wind gusts, gun blast over pressure, and thermal shock.
They are not influenced by radar vicinity and exhibit negligible
infrared and radar signatures. All sensors and their related electronics
are located in the ruggedized body of the probe. FIDELITY Thermal
Anemometers are well suited for military combat, naval vessels,
and meteorological applications where precise measurements and reliability
are essential. All sensors are built to military specifications
and are fully qualified for use on tank fire control systems.
