Magnetostrictive LDT for High Shock and Vibration Areas


*** Call, email or live chat today with any questions or to place an order! ***

Gemco brand position sensing products have been known for survival in harsh industrial environments. We have taken over twenty years experience in magnetostrictive linear sensors and married it with our understanding of rugged industrial sensors to develop the BlueOx LDT as the industry’s first truly rugged magnetostrictive linear transducer.

The BlueOx LDT is lab tested and field proven to stand up to high shock and vibration. With test results of 2,000 Gs of shock and 30 Gs of random vibration without false signals or mechanical damage, the BlueOx LDT is ready to perform on the most demanding applications.

In addition to its ability to withstand shock and vibration, the BlueOx LDT is rugged in other ways. Sensing tube construction is welded stainless steel, suitable for insertion in 5000 PSI hydraulic cylinders. The electronics are enclosed behind an aluminum housing with O-ring seals for IP67 indoor applications (Type Nema 6 rating and stainless steel covers and connectors are available as a special option).

The 952 BlueOx is available with Analog, Control Pulse, Variable Pulse or RS422 Start/Stop outputs. The 952 is compatible with PLC interface cards and our 1746 LDT Interface Card. The 16 bit resolution analog output is programmable over the entire active stroke length. The units can easily be changed in the field from a 0 - 10 VDC to a 10 - 0 VDC or a 4 - 20mA to a 20 - 4mA. As an added feature, the optional differential analog output allows the distance between two magnets to be measured.

The BlueOx, with its high resolution and rugged construction, is at home in heavy duty areas such as lumber mills, steel mills, stamping plants, assembly automation, material handling, robotics and any other industry where highly accurate and reliable continuous linear position sensing is needed.

952QD BlueOx Magnetostrictive LDT with Quadrature Output

The BlueOx Quadrature is a magnetostrictive linear displacement transducer (LDT) for continuous machine positioning in a variety of industrial applications. The quadrature output makes it possible for customers to have a direct interface to virtually any incremental encoder input or counter card, eliminating costly absolute encoder converters and special PLC interface modules.

The BlueOx Quadrature LDT is lab tested and field proven to stand up to high shock and vibration without effect. With test results of 2,000 Gs of shock and 30 Gs of random vibration without false signals or mechanical damage, the BlueOx Quadrature LDT is ready to perform in the most demanding applications.

The BlueOx Quadrature LDT can be ordered with 1 to 9999 cycles per inch of output resolution and the position data is absolute. The transducer features an input to re-zero the probe “on the fly”. Another unique feature is the “burst” mode. An input on the transducer triggers a data transfer of all the incremental position data relative to the transducer’s absolute zero position. This can be used to achieve absolute position updates when power is restored to the system.

The BlueOx Quadrature is shipped from the factory pre-calibrated and ready for installation. In addition to its ability to withstand shock and vibration, the BlueOx Quadrature is rugged in other ways. Sensing tube construction is welded stainless steel, suitable for insertion in 5,000 PSI hydraulic cylinders.

The electronics are enclosed behind an aluminum housing with O-ring seals. The BlueOx Quadrature LDT, with its rugged construction, is at home in heavy duty areas such as lumber mills, steel mills, stamping plants and any other harsh environment where accurate and reliable continuous linear position sensing is needed.
