Wintersense SDI-12 Non-Invasive Surface Temperature Sensor

Forecast winter treatments for road surfaces, prevent traffic accidents and loss of life

9 ₫

The Wintersense SDI-12 is a remote road surface temperature sensor designed for use with your Road Weather Information Systems (RWIS). It is an easy-to-deploy, non-invasive, compact, and lightweight sensor that you can mount on existing roadside structures such as streetlight columns or RWIS towers. The Wintersense SDI-12 has a cabled connection for power and communications with an RWIS station or data logger for data storage and forwarding.

With accurate, real-time road surface temperature data, you can forecast your winter road treatments, preventing traffic accidents and potential loss of life.

The Wintersense SDI-12 is equipped with a thermopile sensor that detects the presence of thermal radiation emitted from the target surface. The sensor also has an integrated optical filter that cuts off the visible and near-infrared radiation flux so that you get optimum ambient and sunlight immunity. These features, combined with an eight-second signal-averaging algorithm, provide you with best-of-class data for these measurement parameters:

- Road surface temperature
- Air temperature
- Relative humidity
- Dewpoint
- Installation angle
- Sensor temperature

Benefits and Features

- Accurate
- Non-invasive
- Easy to install
- Simple to maintain
- Compatible with most data loggers and RWIS
- Remote firmware updates

Accuracy at -40 to +60°C	±0.5°C Note: Accuracy is temperature dependent. The quoted accuracy is against a blackbody source within the ambient temperature range of -20 to +50°C and object temperature range of -40 to +60°C.
Resolution	±0.01°C
Field of View (FOV)	10° (at 50% normalized signal) Note: Use our field-of-view tool to make your calculations and install your Wintersense SDI-12 appropriately.
Distance to Target	2 to 15 m (6.6 to 49.2 ft)

Dew Point Temperature (Calculated)
Measurement Range	-40 to +70°C (-40 to +158°F)
