Überblick

Der Wintersense SDI-12 ist ein berühungsloser Oberflächentemperatursensor, der vor allem für Straßenoberflächen zum Einsatz an einer Strassenwetterstation (RWIS) entwickelt wurde. Er ist leicht anzubringen, nicht-invasiv, kompakt und leicht und man kann vorhandene Strukturen wie Straßenlaternen oder RWIS Masten zum Aufbau verwenden. Der Wintersense SDI-12 hat ein Kabel zur Stromversorgung und zur Kommunikation mit einer RWIS oder einem Datenlogger, der die Daten speichert und weitergibt. a 

Mit genauen Straßenoberflächentemperaturdaten in Echtzeit können Sie Ihren Winterdienst optimieren und so Verkehrsunfälle und potenzielle Verluste an Menschenleben verhindern.

Technische Beschreibung

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

Road-Surface Temperature

Measurement Range -40 to +70°C (-40 to +160°F)
Accuracy at -40 to +60°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.
  • ±1°C or better
Resolution ±0.01°C

Air Temperature

Measurement Range -40 to +70°C (-40 to +160°F)
Accuracy at -40° to +70°C ±0.2°C
Resolution ±0.01°C

Relative Humidity

Measurement Range 0 to 100%
Accuracy at -40 to +60°C < ±3%
Resolution 0.1%

Dew Point Temperature (Calculated)

Measurement Range -40 to +70°C (-40 to +160°F)
Accuracy at -35 to +50°C
  • Note: The calculated dew point temperature is found from Tetens' equation solved for dew point with coefficients optimized for the temperature range -35 to +50°C.
  • ±0.2°C
Resolution 0.1°C

Kompatibel mit

The Wintersense SDI-12 is SDI-12 v1.4 compliant and is compatible with all SDI-12 compliant recorders and all Campbell Scientific RWIS stations. Please check with the manufacturer of any non-Campbell Scientific RWIS station to determine compatibility with the SDI-12 industry standard.
