FN3148
Load Cell with mechanical stops
SPECIFICATIONS

Ranges from 10 N to 2 000 N [2.25 lbf to 450 lbf]
S-Beam sensor in tension and compression
Combined linearity & hysteresis < 0.05% F.S.

The FN3148 high precision load cell is protected against
accidental overloads in tension and compression.
High-level outputs are available with amplifier A1 or A2
integration.
For lower ranges, another sensor, model FN3280, canmeasure 0-1 N to 0-5 N [0.2 lbf to 1 lbf].

FEATURESHigh accuracy
Integrated Amplifier optional
Cable or connector output

APPLICATIONS

Process control equipment
Medical Instruments
WeighingLaboratory and ResearchCalibration test benches
