ASG Adds MHE-7 Series LVIT 

Alliance Sensors Group, a division of H.G. Schaevitz, has expanded its in-cylinder position sensor product line to include the embeddable MHE-7 Series linear inductive sensors. 

The MHE-7 Series LVIT offers more robust construction and a lower cost of ownership than other embeddable in-cylinder sensing technologies. 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 blind hole in the cylinder rod to sense the rod’s position without requiring targeting elements to be assembled to the piston.

Features include nominal ranges from 25mm to 900mm (1 inch to 36 inches), contactless sensing for long sensor life, easily adaptation to existing cylinder designs, integral high-resolution electronics with choice of analog I/Os, and SenSet feature for field scalability of analog output.

An MHE-7 has a 28-mm (1.10-inch) diameter sensor head with an O-ring and back-up ring in a groove, so it can be mounted an industry-standard 28-mm (1.10-inch) 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 suffers no output signal deterioration over the life of the sensor. Because it uses a simple inductive coil, an MHE-7 sensor can withstand much greater shock and vibration than other technologies.
