The Aerovane® Model 135 Wind Indicator is used with the Aerovane® Wind Transmitter and provides a constant visual indication of wind speed and direction for use in meteorological observations and monitoring of wind speed and direction.
- Accurate, Rugged, Reliable
- Illuminated, East to read 4″ front panel meters
- Parallax free reading
- Continuous update linear scales for land station or shipboard applications
- One Aerovane® sensor drives two Model 135 indicators or up to five Model 136 indicators
The wind speed indicator is a jeweled voltmeter, and the wind direction indicator is a torque-receiver synchro. The indicators require 115V, 60 Hz, power.
The wind speed indicator has a range of 0 to 120 knots (other options are available – see ordering information). The wind direction is indicated by degrees and compass points.
Calibration available in knots, miles/hour, and kilometers/hour Direction dial graduated in degrees and compass points for land use or degrees only for shipboard use.
The Standard Aerovane® is capable of driving a maximum of two Series 135 Indicator stations. If specifications require additional indicators, the 136 Marine Wind System should be chosen. The 136 System features an amplifier that enables the master indicator to drive up to four additional repeaters. A typical 136 package includes two Model 120 Transmitters for installation on the ship’s yardarms. Two sensors are required shipboard to permit the bridge to select the windward sensor. Data taken from the leeward sensor can be a distortion of actual ambient conditions, due to deflection or slowing of the wind by the ship’s superstructure. PLEASE CONTACT BELFORT FOR ASSISTANCE WITH MODEL 136 SYSTEMS. The Model CV-3 Signal conditioner can be mounted within the indicator or supplied on a separate 19″ rack mount. The CV-3 converts the analog signals of the wind sensor to proportional d.c. voltages of 0 – 1 or 0 – 10 VDC. An optional 4-20 mA current output is also available. A 60 to 400 Hz converter is available to interface with navigation or fire control equipment.
