Rugged Compact Canister Compression Load Cell-Series CNR950
Standard for most sizes are welded on or Hermetic bolt on electrical connectors made of stainless steel.
Other features you can expect include a 5 point calibration record (NIST traceable) as well as vibration and shock protection.
DESCRIPTION
The Series CNR950 load cells are compact canister designs for
compression force applications. These load cells incorporate an
integral spherical load button.
The CNR950 is constructed of welded stainless steel for the
most demanding application environments. Hermetic bolt on
or welded on stainless steel electrical connectors are standard
for most sizes. Additional features include shock and vibration
protection and each unit is shipped with a 5 point calibration
record traceable to NIST, both as standard.
