Product information "Single point load cell H40A"

The H40A 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 H40A is approved to OIML R60 up to 4000d and gives extremely accurate reproducible results, over a long term even in harsh industrial environments. Each individual load cell H40A 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

The construction of a platform scale with this load cell is very easy. Two steel or aluminum plates of up to 500 x 500 mm are screwed onto the two screw-on surfaces at the top (front) and rear (bottom) at the cable outlet. A parallel connection of several platform load cells is only possible with a balanced output (nominal value and output resistance).
