dataTaker Solution The dataTaker DT50 was powered directly from the truck’s 24VDC battery. The sensors listed are installed around the truck and are connected to the data logger. The logging of data from the sensors is controlled by the SPRAY ON and SPRAY OFF push buttons on the drivers panel beside the steering wheel. This provides a safe voltage free contact closure input to the data logger, which is normally closed. Pressing the SPRAY ON button activates the data logging relay and opens the contacts. Pressing the SPRAY OFF button de-activates the data logging relay and closes the contacts. The Run Number counter is reset to zero each midnight, so that the first run each day is Run Number 1. Elapsed Spray Time – this counter is set to zero when the SPRAY ON button is pressed, and is incremented each second during a spray run. The Elapsed Spray Time is logged each second along with the sensor data for that second. Data can be viewed in real time during spray runs if desired, by connecting a computer running DeTransfer (supplied on the Resources CD supplied with the data logger) to the data logger’s RS232 Comms connector. Viewing data in this way does not disrupt saving the data to the memory card as well. Also the data can to downloaded as a CSV file using DeLogger, allowing further analysis in Microsoft Excel. Currently this project is ongoing and there is a likelihood of this system being replicated throughout the fleet.
