The MR-7 Series Inductive Linear Position Sensor from Alliance Sensors Group is designed to be a drop-in, form, fit and function replacement for magnetostrictive sensors but with a much more robust construction and at a lower sell price and cost of ownership. Available in Ranges from 2" to 36", the MR-7 was designed to specifically target port mounted industrial or subsea hydraulic and pneumatic actuator and cylinder applications.
The MR-7 Series is based on proprietary, contactless inductive sensing technology that employs a unique solid 7mm diameter probe construction and only requires a simple conductive tube target (or simply the gun drill ID of the cylinder rod) for operation, rather than a magnet or some other special target type.Resembling a magnetostrictive sensor with a sensor head, threading and a sensing rod but with a shorter stroke to length ratio, the MR-7 can thread into the same location that is configured to accept a magnetostrictive sensor and for applications where the MR-7 is replacing an existing magnetostrictive sensor, the magnet can be left in place and will not affect the performance of the sensor. Being contactless the MR-7 Series is not subject to wear and experiences no output signal deterioration over the life of the sensor.
The MR-7 1.750" OD housing with 1.750" hex housing and thread mounting are the same configuration as typical magnetostrictive sensors. By using an inductive coil rather than wires and “time of flight" technology the MR-7 can withstand much greater shocks and vibrations.
