AvionTEq is able to supply the Loop Resistance Testers (LRTs) required for aircraft maintenance, resistance testing, and electrical safety. Whether one is looking to rent or buy, we have new, used, and refurbished units on hand. For the technician, this is the sort of specialized gear necessary to test the cable shields and shield connections in an airplane’s wire bundles and confirm that every piece of critical wiring is as it should be.
In use, an LRT will inject current into the loop via clamps or couplers. With the current in motion, the device will determine the voltage required to sustain it and use that figure to work out the loop’s impedance or resistance. This gives maintenance crews a means of obtaining calibrated data as they evaluate a shield connection. In doing so, they can identify high-resistance joints and avoid the kind of troubleshooting mistakes that might otherwise occur.
There is no room for compromise in aircraft applications when it comes to grounding, lightning protection or the integrity of an electrical system; all are matters of safety and reliable operation. A well-calibrated LRT provides the data for your maintenance records and can do away with some of the more time-consuming manual work, in keeping with Boeing and other industry requirements.
We are here to assist in locating the right LRT model to fit an aircraft’s standards and the customer’s particular maintenance profile. Any refurbished stock we put forward has been put through its paces and will come with a new calibration certificate if called for. We also purchase surplus or excess LRTs and will take trade-ins on other aviation test gear.
