PD-232 Advanced Microprocessor Vehicle Loop Detector
The PD-232 is a double-channel inductive loop detector featuring
advanced microprocessor technology with 10ms fast reaction time.
Utilizing automatic calibration upon power application, this
vehicle detection system operates by detecting changes in loop
inductance caused by metallic vehicle components.
