DESCRIPTION
The RTM300/500 vehicle detection system monitors changes in the earth’s
magnetic field caused by passing vehicles and signals this change to the
controller as a detection event.
The RTM vehicle sensor system - comprising the RTM300 sensor and the
RTM500 interface card - is specifically designed for use at traffic signal controlled
locations for the detection of vehicles. It has been designed to be retrofitted at
failed loop locations and can also be installed at new locations during site
refurbishment or during site highway works.
It is easy and quick to install, with the interface card fitting into the controller in
exactly the same manner as a loop detector card, and the sensor into available
ducting, or as defined in section 6 below.
Each RTM500 interface card can support up to 4 RTM300 sensors. Each sensor
takes power and set up data from, and signals detection events to, the interface
card over a two wire link which may be either new or legacy loop feeder cable.
