The MHE-7 Series LVIT (Linear Variable Inductance Transducer) Position Sensor from Alliance Sensors Group offers more robust construction and a lower cost of ownership than other embeddable, in-cylinder sensing technologies, making the MHE-7 the preferred choice of cylinder users. These sensors can be embedded into the end cap of industrial or mobile hydraulic cylinders or electric linear actuators and are based on a contactless inductive sensing technology that employs a 7 mm diameter probe with a shorter stroke-to-length ratio than most other sensing technologies. It uses a simple, gun-drilled, blind hole in the cylinder rod to sense the rod's position without requiring any targeting element(s) to be assembled to the piston.
An MHE-7 has a 28 mm (1.10 inch) diameter sensor head with an O-ring and back-up ring in a groove. It can be mounted in an industry standard 28 mm diameter cavity in the cylinder cap and locked in with radial set screws or a snap ring. Being contactless, an MHE-7 Series sensor does not wear out and has no output signal deterioration over the life of the sensor because it uses a simple inductive coil. The MHE-7 sensor can withstand much greater shock and vibration than other technologies. The MHE-7 is also offered with ASG’s proprietary SenSet™ feature whereby a sensor’s analog output can be easily adjusted after installation to match the range of motion of the cylinder rod.
