Overview

The R.M. Young Model 86004 Ultrasonic Anemometer is a 2-axis, no-moving-parts wind sensor with integral 60 watt heater for use in cold climates. It is ideal for general meteorological applications requiring accurate and reliable wind measurement. Heaters integrated into the transducers and housing enhance performance in cold conditions.

The sensor features durable, corrosion-resistant construction with sensitive ultrasonic transducers secured in a streamlined molded frame. The 86004 is fully wind-tunnel tested and calibrated to provide accurate wind measurement over a wide operating range.

Technical Description

The standard sensor offers a variety of useful output options. Analog voltage outputs are provided for wind speed and wind direction. A variety of serial output formats are also available. These include ASCII text, RMYT (compatible with R.M Young displays), and NMEA formats.

The sensor installs on readily available 1 inch (IPS) pipe. Wiring connections are made in a convenient weatherproof junction box; special mounting adapters and connectors are not required.
