Steel Mill LVDT Position Sensor Reduces Mill Downtime
with Long Term Operation, Easy Installation

Rugged LVDT is designed for easy installation, calibration and configuration

Pennsauken, NJ, January, 2012…

Macro Sensors new non-contacting LVDT Position Sensor keeps steel rolling mill operations running smoothly with less downtime. Ensuring quality control during steel production, Macro Sensors Steel Mill Position Sensor monitors the position of milling frames that support rollers during the hot rolling process. Position feedback ensures frames don’t deform or shift during the rolling process. These non-contacting LVDTs can also be used to monitor the position of the rollers themselves.

The highly rugged and robust LVDT offers long-term operation within the high temperatures and harsh environments of steel rolling mills. Environmentally sealed to IEC standard IP-68, rated to 185°F (85°C), and protected against dust ingress, this linear position sensor resists moisture and contamination from airborne particulates and other dirt and grime inherent in steel mills.

While other LVDTs require a great deal of downtime for installation or replacement, this unit is specifically designed for easy calibration, configuration and installation. 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 the non-contacting Steel Mill Position Sensor 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.

Macro Sensors offers its non-contacting Steel Mill Position Sensor 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 ±0.015 inch (±0.38 mm) to ±10.0 inches (±250 mm).
