DESCRIPTION
Model 1242 is a high accuracy, low profile,
low cost, two beam, single point load cell
ideally suited for industrial application
where space is limited. Typical applications
include platbs, hanging scales and
personal weighers.
This high accuracy load cell is OIML R60
class C6 approved. For hazardous
environments this load cell has EEx ia IIC
T4 level of approval, as well as Factory
Mutual approval.
A special humidity resistant protective
coating assures long term stability over the
entire compensated temperature range.
The two additional sense wires feed back
the voltage reaching the load cell.
Complete compensation of changes in
lead resistance due to temperature change
and/or cable extension can be achieved by
feeding this voltage into the appropriate
electronics.
APPLICATIONS
• Small platbs
• Hanging scales
• Personal scales
