Macro Sensors’ HLR 750 Series of 3/4 inch diameter high reliability LVDT position sensors are specifically designed for use in gas turbine environments. Rated for operation to 300°F (150°C), these hermetically sealed AC-LVDTs are listed for Class I, Division 2, Groups A, B, C, D and Class I, Zone 2, Group IIC hazardous locations by Underwriters Laboratories.

The Macro Sensors SQ 1250 Series of heavy duty LVDTs were developed specifically to measure position or motion in mill-type hostile environments. These rugged and reliable contactless sensors, available in measuring ranges from ±0.50 inches to ±10.00 inches, have their electrical assembly totally encapsulated within a heavy duty aluminum housing, with their electrical connections made to screw-terminal style barrier strips. This complete encapsulation of SQ 1250 Series LVDTs allows them to withstand the high shock and vibration levels typically encountered in mill environments and permits them to meet the IEC IP-64 sealing standard against the intrusion of splashed water and other liquids.

The SI 750 Series of 3/4 inch diameter, loop powered 4-20 mA LVDT position transmitters is designed for a wide range of position monitoring and feedback applications. Their stainless steel housings act as magnetic shields to reduce the effects of external AC magnetic fields, and their sealing meets IEC standard IP-62.
