OIML R60. C3 or C6 precision class.

Stainless steel. IP68/IP69K protection.

This fully welded stainless steel bending beam load cell is hermetically sealed to IP68 / IP69K and can be used in the harshest industrial environments. It is suitable for weighing platforms, bag fillers, belt weighers and tank weighing in the Food Processing, Chemical, Pharmaceutical and general Bulk Handling industries.

OIML C3 or C6 approved versions are available. A 6 wire cable (with Sense wires) is supplied as standard.
For applications in aggressive environments where stress corrosion or acid attack is an issue, a special Parylene coating can be specified as an option. High temperature variants for continuous operation in environments up to 150˚C are also available.
