Multi Loop Tester (MLT)
Excel has designed and manufactures a Multi-Loop Tester (MLT) unit for the qualification of multiple loops at once. The MLT is a field service device for in-pavement loop analysis, measuring all relevant loop parameters (inductance, DC series resistance, 'Q' performance factor and tuned frequency) for a group of up to eight (8) in-pavement loops at once. The unit communicates via serial (or serial<>USB conversation) with Excel's proprietary user interface in order to download and save data in .csv format.
The unit has been designed to interface with a number of 'adapters' currently suited to the ribbon cable output from our own Field Termination Panel (FPT), a block of eight loop terminals, and Tyco-Philips detector modules.
The software tool facilitates the following functions:
- Enter site name and details
- Enter detector type / manufacturer
- Select loop block (i.e. 1-8, 9-16)
- Create file name from above details to confirm or change via
- Initiate test sequence of eight loops - display progress / completion
- Display data - loop inductance, DC resistance, 'Q' factor and tuned frequency
- Transfer data to a permanent .csv file storage on laptop
- Confirm data storage or clear and repeat
- Terminate program or continue
