Product #GS320/026

This kit contains the the GS026 Wireless Wind Speed Sensor and GS320 Wind Speed Display. Below are descriptions of each.


The GS026 Wind Speed Sensor from Trimble’s Lifting Solutions Division offers a user-focused and cost-effective design to the market.

For applications requiring a wireless wind speed unit, the GS026 has the best market value.

Whether the application is residential, commercial, marine or heavy industrial, the GS026 offers the best value for the money based on features, functionality and radio performance.

The GS026 Wind Speed Sensor has a communication range of 4,600 feet (1,400 meters)

RF signals are always present in the day-to-day atmosphere. There are many products that advertise extremely long-distance communication ranges, but due to RF interference those advertised range claims can often be reduced by up to 75%.

At Trimble’s Lifting Solutions Division, we have developed our own radio technology that has been market-proven in worldwide applications. Our proven technology has very minimal effect from RFI intrusion.

The GS026 Wind Speed Sensor’s innovative design provides users with a wide range of cost-saving features and vastly simplified product support.

Design features include:

  • Communication range: 4,600 feet (1,400 meters)
  • Measurement range: 0 to 150 mph (0 to 241.4 km/h)(The GS320 display shows a maximum wind speed of 99 mph)
  • Typical accuracy: +/- 3 mph (+/- 4.8 km/h)
  • User-replaceable wind cup assembly
  • Simple and easy battery change
  • Powered by either a 3.6V lithium battery or a 1.5V alkaline battery

Users can expect up to 3 years of battery life under normal operation. If wind speed was monitored continuously 24 hours a day / 7 days a week, users could expect 20 months of battery life from one “D” cell lithium battery.

The wind speed sensing element has no moving parts. The wind cup head assembly has 2 embedded magnets that pass by a reed switch in the wind speed body as the wind speed head assembly turns, producing an accurate wind value.

The GS026 Wind Speed Sensor pivots on its steel mounting bracket, useful in applications where the structure it is mounted on moves up and down, such as with cranes or other lifting equipment. This keeps the wind cups perpendicular to the wind, the ideal angle to accurately measure the wind speed.


The GS320 Wireless Wind Speed Display offers maximum benefit for crane applications where wind speed monitoring is critical.

In the crane industry, wind is a potentially deadly element in the day to day operating environment.

Our GS320 Wind Speed Display and GS020 Wind Speed Sensor offer users an effective and proven solution for monitoring wind speed.

The GS320 has an operating range of 4,300 ft (1,300 m).
This range is especially effective when working in and around wind turbines. Wind turbines output a very strong RF signal, and our innovative technology has been perfected to work in this uncompromising environment.

Our technology is also very successful when installed on long boom lattice cranes. While a 500 ft lattice boom often presents challenges for other systems, a Trimble system will effectively and efficiently communicate with the cab mounted display.
The GS320 Display will show the wind value in MPH or meter per second. You will also be able to set a wind speed warning limit which will provide an audible and visual alarm when the limit has been reached.

A key installation tip is to ensure that the wind speed sensor is placed at the boom tip of the crane, as compared to the top of the crane cab. There have been many avoidable accidents due to a cab-mounted wind speed sensor.

One of the major advantages of Trimble’s two-way radio communication is the management of battery life. When the GS320 Display is turned off, the GS020 Wind Speed Sensor stops active transmission. At that point, it simply listens for the display to say that it is back online. This process uses virtually no battery life.

The GS320 also controls the radio power level of the GS020
Wind Speed Sensor. The GS320 Display will automatically increase
or decrease the radio power on the GS020 Wind Speed Sensor depending on the signal strength. This ensures effective communication at all times and optimizes battery life. The typical battery life of our GS020 Wind Speed Sensor is 2 years.
