Product information "Single point load cell H44A"

The H44A is a single point load cell made from Aluminium. The load cell is suitable for bench scales, platform scales and weighing machines with accuracy class III.  The load cell H44A is approved to OIML R60 up to 3000d and gives extremely accurate reproducible results, over a long term even in harsh industrial environments. Each individual load cell H44A is corner adjusted and optimised for out of center load sensitivity. This ensures that there will be no measurement error when the load is placed off centre, eg in a corner of a platform.
The load cell is potted and meets the requirements of protection class IP65.

Mounting

montage_h44a

The large screw-on surfaces and four threaded holes at the front and rear provide ideal conditions for the problem-free construction of a scale with large platform dimensions. The construction of a platform scale with this load cell is very easy. Two steel or aluminum plates of up to 600 x 800 mm are screwed on via the two screw-on surfaces above and below or at the front and back of the cable outlet. A parallel connection of several platform load cells is only possible with a balanced output (nominal value and output resistance).
