RWS200 Product Catalog / Vaisala Road Weather Station RWS200 For Roads, Rail, and Runways

VAISALAVaisala Road Weather Station RWS200 To keep the roads and runways safe and passable at all times, the pavement and atmospheric weather must be continuously monitored. Weather conditions such as snow and ice, heavy rains, fog, high winds, and sand storms can impact road and runway safety in many different ways. Unfortunately, you cannot usually observe the weather impact from your office window so it is important to have a reliable tool for information gathering. Road weather stations, also known as Road Weather Information Systems (RWIS), have been developed for several decades to collect...

VAISALA RWS200 is equipped with smart power management. The full-featured RWS200 comes with a backup battery. When main power is lost, RWS200 detects the change and begins shutting down operations that drain the most power. This ensures that in an environment where power is not always stable, RWS200 continues to provide observations and access to the system as long as battery power is available. Vaisala sensors are sold around the world for many different applications, both separately and with Vaisala weather stations. RWS200 supports a large range of Vaisala sensors and a selected set of third-party...

VAISALA RWS200 is reliable, sustainable, expandable, and upgradable. It provides remote access for maintenance and for viewing the observations. You can also integrate RWS200 to your data collection system using the various interfaces it offers. RWS200 comprises of high quality components that have been specifically designed for and tested in harsh conditions. Each RWS200 system is thoroughly tested before it leaves the Vaisala factory. A comprehensive documentation set, including the test reports, is delivered with each RWS200. Road Specific Design Vaisala offers a wide variety of sensors for...

Remote Road Temperature Sensor DST111 The DST111 sensor provides a remote alternative to measuring road surface temperature. By measuring the infrared radiation emitted by the surface and applying intelligent signal processing, DST111 provides a reliable remote surface temperature measurement. The sensor has a faster response time than traditional road temperature sensors and therefore provides a good option for special locations, such as bridges. General Specifications Operating temperature Storage temperature Operating humidity Communication interface Dimensions (H × W × D) Weight Cover Mounting...

The DRS511 sensor, when connected to RWS200, forms a part of a complete remote processing system for ice warnings and predictions. The durable design of the sensor withstands the heavy stress of traffic, allowing the sensor to be installed in the wheel track. Vaisala’s unique measurement technologies enable accurate analysis of road state, snow and ice coverage detection, water-film thickness, amount of de-icing chemicals, and depression of freezing point. Temperature sensors Two Pt100 elements, 1/3 Class B DIN 1EC 751 Dimensions (H x W x D) 75 x 30 x 84 mm, bottom 38 mm 50 m/165 ft cable...

The FP2000 sensor monitors the condition of the road surface and determines if there is water or a chemical solution on the road. The data is used for maintenance operations during critical winter periods and throughout the year. Available in North America only.
