Technology Behind the Insight® Air Cylinder

QVLA® is a precise, repeatable and long lasting measurement system working on the simple principle of measuring light intensity within the air cylinder. As the piston moves more cylinder wall is available to absorb light thereby resulting in changing light intensities within the cylinder indicating rod extension.
iNSiGHT® replaces reed switches providing identical electronic outputs, easier set-up by a permanently attached keypad on the outside of the cylinder and can also be used for an end of stroke sensor. Unlike traditional switches, which can be run over with speed, iNSiGHT® establishes "end zones." Once a position is tripped an "end zone" of switched electrical signal is established.
iNSiGHT® has no magnets or coils, extremely low electrical noise and is inherently wield field immune. It works with steel, aluminum or opaque composite structures.
iNSiGHT® Series cylinder is made in two footprints. The "Dprint" is our basic D Series cylinder line with 1.25", 1.75", 2" and 2.5" bore cylinders. The "Kprint" is our NFPA K Series cylinder with 1.5", 2", and 2.5" bore cylinders. All typical mountings available.
9 foot cable standard.
