January 13, 2015 - Alliance Sensors Group announces MHP in-cylinder position sensor. These compact inductive linear sensors can be installed into the rear endcap of hydraulic cylinders for operation at pressures up to 5000psig. Their 1-inch hex aluminum or stainless steel housing are ideal for mobile hydraulics, factory automation machinery, or oil and gas exploration equipment, and mount to the cylinder with a standard male o-ring port thread.
Features of the MHP:
No magnet required
Compact 1-inch hex aluminum or stainless steel housing
Contactless- no wear from cycling or dithering
Ranges from 50 to 600 mm (2 to 24 inches)
Excellent stroke-to-length ratio
SenSet for field scalability of analog output
The MHP series sensors are based on a contactless inductive sensing technology with a short stroke to length ratio. They employ a 7 mm diameter probe inserted into an 8 mm (5/16 inch) gun-drilled hole in the cylinder rod to measure position rather than a ring magnet or pot contact spool. They are offered in ranges from 50 to 600mm (2 to 24 inches) full scale with a wide variety of on analog I/Os and either connector and cable terminations.
The MHP series also includes the MR and ME series for larger cylinders and actuators.
