The MHP-7 Series LVIT (Linear Variable Inductance Transducer) Position Sensors from Alliance Sensors Group were designed to be installed into the rear endcap of hydraulic cylinders having an SAE J1926-08 or ISO 6249-M18 female O-ring port. Their 1-inch hex aluminum or stainless steel housings are ideal for operation up to 5000 psig (350 bar) in high pressure mobile hydraulic systems, factory automation machinery, or oil and gas exploration equipment.
The MHP-7 series sensors are based on a proprietary contactless sensing technology with a good stroke-to-length ratio. They employ a 7 mm diameter sealed inductive probe inserted into a target tube mounted inside of a gun-drilled hole in the cylinder rod to measure its position rather than using a ring magnet or a potentiometer’s contact spool. They are offered in full scale ranges from 25 to 900 mm (1 to 36 inches), with a wide variety of analog I/Os, and either connector or cable terminations. The MHP-7 is also offered with ASG’s proprietary SenSet™ feature whereby a sensor’s analog output can be easily adjusted in the field after installation to match the range of motion of the cylinder rod.
