Description
FN9620 HARSH ENVIRONMENT S-BEAM LOAD CELL
The FN9620 is a S-Beam load cell with ranges from 500N to 10kN, designed to operate in hostile environments from -40 to 90°C with IP68 ingress protection.
It provides high stiffness for high cycle use, low off-axis load sensitivity and high level of accuracy.
To ease its use for Process Control Automation equipment, the sensor’s sensitivity (in mV/V) is calibrated with
2% tolerance. On request, Instruction documents can be provided to ease the selection and use of our sensors and provide helpful tips.
