Vaisala TempCast is an easy and affordable way to monitor key temperature parameters from any critical location. The wireless, pole-mounted sensor has different variants to measure air temperature, relative humidity, and surface temperature.
Monitor frost formation on roads
Surface and dew point temperatures are important when assessing the risk for frost formation on the roads. TempCast reports high-quality observations and enhanced point forecasts so that you can be prepared for what is ahead within the next 72 hours. This information allows you to make the right treatment decisions and act at the right time.
Get measurements from locations not feasible before
TempCast is wireless and mounts to existing infrastructure allowing flexible installation to various locations. External powering is not required. This makes it a cost-effective solution for covering data gaps in your existing weather observation network and an ideal starting point for gaining access to local weather observations.
Sensor replacement takes 5 minutes
The sensor does not need any maintenance during its lifetime. It has an automatic self-cleaning function that removes contamination from the humidity sensor. At the end of its life, the sensor is replaced with a new one. There is no need for a crane or a ladder to
access the sensor. The replacement takes 5 minutes by a single person from ground level by using a telescopic rod. The sensor is secured to its mounting bracket with a convenient twist-lock mechanism. This ensures that the replacement process is fast and safe.
Easy access to data
Measurement data from TempCast is automatically available in Vaisala Wx Horizon. Wx Horizon combines local sensor observations, radar data, and alerts in one subscription package for enhanced road weather forecasts. For integration to other systems, the Wx Horizon API can be used.
Best performance with Vaisala GroundCast
TempCast with remote surface temperature measurement is a convenient product for frost monitoring. When you want to monitor ice formation as well and further enhance your road weather forecast, you can co-locate TempCast with Vaisala GroundCast.
