Aerovane Indicator Model 135
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.
Features
The wind speed indicator is a jeweled voltmeter, and the wind direction indicator is a torque-receiver synchro. The indicators require 115 V, 60 Hz power.
The wind speed indicator has a range of 0 to 120 knots (other options are available). The wind direction is indicated by degrees and compass points.
- Accurate, Rugged, Reliable
- Illuminated, Easy 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
Standard Features
- 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
Options
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 120Transmitters 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.
