Asphalt state temperature, aqueous film, freezing and residual salt
Asphalt status sensors

Asphalt state temperature, aqueous film, freezing and residual salt

Different versions of the same sensor are made to measure also the underground temperatures using separate sensor units. Main difference between DQA352 and DQA353 is the better accuracy of the DQA353 in the Water film thickness and Freezing point temperature specifications. DQA352 has RS485 output with an open protocol suitable for connection to LSI LASTEM and Boschung data loggers as well as third part integration systems. DQA353 has a Boschung proprietary protocol only. DQA352-353 sensors are made by Boschung Mecatronic AG. Surface temperature, asphalt state and aqueous film Highlights These sensors accurately report the following parameters: Road surface temperature; Road conditions; Water film thickness on the pavement; Model codes: DQA352.0, DQA352.0E, DQA352.1E, DQA352.2E, DQA353.0, DQA353.0E, DQA353.1E, DQA353.2E.
