| Deltapoint resistance welding tip-loss monitors  Rocon announces DeltaPoint tip-loss monitors with DeviceNet interface for protecting critical welds and helping assure quality in resistance welding robotic applications. DeltaPoint monitors from Rocon 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 DeltaPoint monitors can provide sensitive tip-loss detection in welding guns, robotic work cells or non-robotic hard tooling. One DeltaPoint unit can monitor up to 13 welding tips.DeltaPoint tip-loss monitors are equipped with vortex shedding flowmeters that require minimal maintenance, are not affected by dirt in water, and have no moving parts to clog, wear or repair. The flowmeters are bench-calibrated to minimize possibility of nuisance tripping. Two flowmeters are used in the monitors to measure water flow in and out and compare flow rate and temperature. If a leak is detected, an alarm is sent to the robot to stop welding, and the water is shut off. The monitor will not allow the welder to operate without water flow, even in bypass mode. Rocon DeltaPoint tip-loss 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. Models in the DeltaPoint series accommodate cooling flows up to 12 gallons per minute and water temperatures up to 230ºF. write your comments about the article :: © 2006 Construction News :: home page |
