Next Generation TT 290 Series Combination Detectors

ASIM is introducing its next generation of triple technology above ground detectors for individual counting,
occupancy, speed and classification by vehicle type for traffic data acquisition in traffic management systems.
Three independent technologies combined in a single detector with adaptive processing of the signals result
in accurate traffic data

  • Doppler radar for accurate speed measurement

  • Ultrasound for height profile and standing vehicles

  • Dynamic PIR detection channels for special functions

  • New features of the next generation TT 290 Series are:

  • Multiple PIR detection channels

  • Extended supply voltage range

  • Choice of new functions and output options
  • A key feature is the new multi zone infrared curtain,
    which gives lane position information of the vehicles to correctly treat lane changing vehicles (all models except
    base model TT 292). The configuration is easily and automatically achieved with the enhanced installation
    As special highlights, the detectors can operate in lanes with alternating traffic directions and can detect
    wrong-way drivers as well.
    Standard models are available for distinction of two, five or eight different vehicle classes respectively
    according to the German TLS specification. For other countries with different specifications more models are
    available. Logic outputs can activate speed or distance warnings, trigger video cameras and more.
    Stainless steel mounting points and brackets with integral alignment guides are just an example of the
    comprehensive and rugged construction elements. The detectors can easily be mounted on bridges, gantries or
    other stable structures above the lane to be observed, side mounting options are available as well.
