CalTrans Monitoring System
This system includes all of the features of the standard panel plus has several additional useful functions. The system can monitor Conveyer Slip Ratio (the timing between the head pulley and the tail pulley and measures slippage between the two and automatically shuts down the conveyer belt if too much slippage is registered). The emulsion tank and aggregate hopper also have safety shut down systems that will stop the production of slurry if they fail to register material flows. All three systems have warning lights with push buttons, which allow the alarm to be shut off during calibration or in case of a malfunction. The emulsion tank and water tank levels are displayed on the computer display. This system also has a calibration mode, which allows it to be preset for a determined number of revolutions for aggregate, emulsion and fines counts and have the unit stop at that number. The CalTrans system also monitors ground travel and when the spreader box width is input into the computer, the production rate and spread rate can be displayed, as well as displaying an average distance remaining per load. In addition, the computer provides automatic maintenance indications based upon filter condition and engine hours. To comply with CalTrans specifications a separate display is provided that can be viewed from the ground next to the machine that displays material usage and shutdown alarms.
