Intelligent in-pavement sensor
for winter service systems
FEATURES
RUGGED DESIGN.
MONITORS PAVEMENT CONDITION.
RS485 OUTPUT WITH OPEN PROTOCOL.
LOW POWER CONSUMPTION
EXCELLENT RESISTANCE TO MECHANICAL STRESS
AND CHEMICAL AGENTS.
DESCRIPTION
The IT-Sens probe has been designed to be
installed in the pavement. IT-Sens WSS basic is
specialized for Winter Service Support.
The direct RS485 output provides outstanding
integration flexibility in any existing or future system.
The very low power consumption and rugged
design make it the ideal candidate for general winter
service applications.
The sensor accurately reports the road surface
temperature and condition, as well as the water film
thickness on the pavement. In addition, freezing
point temperature and chemical factor are
detected. These parameters allow for a tight
monitoring of road conditions for winter service
operations or Intelligent Transportation Systems
(ITS).
This sensor can be used jointly with the Present
Weather (PWS) and/or Air Temperature - Relative
humidity (RF/TL) sensors of the Boschung product
range for a complete Road Weather Information
System.
TRANSPORT PRESCRIPTIONS
The IT-Sens probe should be transported in its original packaging and handled with great care.
