Product Description

SYN-706 – Wind speed & Direction

The Synchrotac SYN706 series has a long history of reliable service in very aggressive environments such as in coastal tropical cyclone areas and oil rigs.

They are solidly constructed from naval bronze, brass, stainless steel and other corrosion resistant materials. Bearings are low friction stainless steel for a low starting threshold.

The instrument is sealed against dust, moisture and vermin ingress and mounts directly on a ¾ inch diameter (speed only) or 1½ inch diameter (speed & direction) male BSP thread. Special bearing lubricants ensure reliable operation over the temperature range and, under normal conditions, should give maintenance-free operation in excess of 10 years.

Models

Three anemometer models and one wind direction model are available in the Synchrotac SYN706 series. The anemometer models available are:

  • The SYN732 – poly-phase linear generator;
  • The SYN734 – solated switch contact closure;
  • The SYN736 for opto-electronic pulse output.
  • The wind direction SYN706 section uses a single precision potentiometer.

The anemometer section may be purchased separately for wind speed only applications. For intrinsically safe and Ex applications, the SYN706 wind direction section and SYN734 wind speed section are classified as “Simple Apparatus” because they use passive sensors (potentiometer and switch) and there are no energy storage components within.
