Keeping steel rolling mill operations running smoothly with less downtime, Macro Sensors’ non-contacting LVDT position sensor monitors the position of milling frames that support rollers during the hot rolling process. Position feedback ensures frames do not deform or shift during the rolling process. The LVDTs can also be used to monitor the position of the rollers themselves. Environmentally sealed to IEC standard IP-68, rated to 85°C, and protected against dust ingress, they resist moisture and contamination from airborne particulates and other dirt and grime inherent in steel mills. A radial configuration with rod ends simplifies installation of the LVDT as there is no need for core rods for connection. Rod-ends make mounting easier, as units can quite literally be dropped into place, which saves on installation time. Units also incorporate pre-calibrated on-board electronics, eliminating the need to configure signal conditioners. Electrical null adjustment also makes for easy positioning. The Steel Mill Position Sensor are offered in 0-10V, 4-20mA, ±10V outputs. Based on the company’s popular HSDR Series of hermetically-sealed DC-operated LVDT position sensors, units are available in ranges of ±0.38 to ±250 mm.
