Ring Master 1000 PLC Proximity Detection
The Ring Master 1000 LD (100mm x 50mm Single Board Computer) uses PWM
and Frequency shift to detect metallic objects. Inductive Loop
Detection unit defies 2/3 shortest leg rule when detecting metallic
mass which includes aluminum passing through detection loop perimeter.
This detector employs a derivative of both Fixed Drive and Ringing Coil
theory thus improving the detection range of slow moving and stationary
vehicles. RS232 PC Serial Port allows the installer to adjust device
sensitivity and frequency settings as well as view diagnostics information
from a computer terminal.
