DeltaPoint tip-loss monitors with DeviceNet interface are designed for protecting critical welds and helping ensure quality in resistance welding robotic applications. DeltaPoint monitors sense tip-loss in resistance welding cells by comparing total inflow and outflow of cooling water to the cell. DeviceNet outputs are a standard feature of the DeltaPoint units, which monitor flow and temperature, provide flow comparisons and detect leaks in multiple weld devices. The monitors can provide sensitive tip-loss detection in welding guns, robotic work cells or non-robotic hard tooling. One unit can monitor up to 13 welding tips. The monitors are equipped with vortex-shedding flowmeters that require minimal maintenance and have no moving parts. The flowmeters are bench-calibrated to minimize possibility of nuisance tripping. The monitors feature remote shutoff and restart and are programmable for leak-rate alarm, time delay, restart delay, temperature fault level, flow okay and minimum flow indication.
