Anemometers Model 300

Anemometer Model 300:
Analog or Digital Output For Measurements of:

  • Crosswind
  • Headwind
  • Crosswind or Headwind
  • Atmospheric Pressure
  • Air Temperature

Fidelity’s Model 300 anemometer series combines the robust physical design and performance capabilities of the analog Model 270 and the output capabilities of the digital Model 500 sensors. Built with more current manufacturing technologies and components, the Model 300 measures either crosswind or headwind or both and reports wind speed and direction, barometric pressure, and ambient temperature. An optional external temperature sensor is available.

The Model 300 sensor suite also features built-in test capabilities. The 300 system was subjected to, and successfully completed, a wide range of military specification qualification tests, including extreme temperatures and humidity, solar, radiation, vibration, shock, salt fog, dust, rain, electrical power surge and electromagnetic interference.

Fidelity’s Patented Thermal Anemometers provide long-term, trouble free operation under most severe climatic, environmental and electromagnetic conditions. They withstand shock, vibration, wind gusts, gun blast over pressure and thermal shock. The Series 300 has long-term stability and calibration repeatability. They are not influenced by radar vicinity and exhibit negligible infrared and radar signatures. A test facility is provided to check proper operation of the electronics. 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. The Series 300 is intrinsically safe in hazardous fuel environments.

All sensors are built to military specification and are fully qualified for use on tank fire control systems.
