TMT & TMT-2 - Doppler Sensors for Overspeed Detection

Doppler Sensors for Overspeed Detection

The TMT & TMT-2 are two doppler sensors designed for vehicle overspeed detection. It allows for the use of one or two relays to regulate Vehicle Activated Signs, and traffic lights.

TMT

  • Detection up to 150 m (492’), 1 relay, setting per DIP-Switch

TMT-2

  • Detection up to 120 m (393.7’), 2 relays, setting per RS232 

Benefits

Above Ground Technology

  • Safer for the traffic engineers, who can stay on the roadside for installation  
  • Less expensive: no roadwork nor traffic interruption needed for installation

Efficient Reliability

  • Frost, snow, fog, etc. have no influence on the radar’s performance
  • No lens to clean means no calibration

Features

Easy to Install

  • Detachable cable at the rear 
  • Delivered ready to install, i.e. including cable, fixing support, screws and bolts 
  • Settings adjustable without radar opening 
  • Extended operating temperature: -40°C/+75°C (-40°C/+167°C)

Applications

  • Intersections
  • Warnings (VMS activation)
  • Wrong-way detection

Options - LP Version

  • Low power consumption for solar power, with open collector output for the TMT
