Profile: A C I C International Ltd. specializes in data acquisition and remote condition monitoring systems. Our product line includes track circuit condition monitoring system, alphameter, relay room temperature monitoring, weather stations, and legacy replacements. Our unit has been designed to detect and monitor excessive rail surface contamination caused by the build up of leaves or Sandex on track circuits currently in use by network rail. The unit operates with AC and DC current transducers, and is therefore suitable for both AC (T1) or DC track circuits. Calculations are performed on each input channel to provide a reading, which is linearized for the particular current transducer, and for calibration purposes.
