Are Hardy Load Cells FM Approved?

Do Hardy Load Cells have FM (Factory Mutual) Intrinsic Safety Approval? If so, how are they installed in a hazardous area requiring FM approval?

The following Hardy Load Cell Models normally have the C2® chip internal and are FM approved:

ADVANTAGE® & ADVANTAGE® Lite Cells
Load Cell	Load Point Type, Mount Type, or Scale Type
HI HBB01	HIONELP & Footed Load Cell Mount
HI HBB06	HILPB Load Point
HI RCH03	HILPRC03 Load Point
HI RCH04	HILPRC03 Load Point
HI SB02	HILPRE
HI SB05	HIONELP, HILPRE05, & HIMSBRE
HI SBH04	HIONELP, HIHLPRE04, HIMSBRE, & HIHLPS
HI SBHF14	Cells for HIFS Floor Scales & Footed Load Cell Mount
HI STH01	HIHLPT Load Point
HI STH06	HIHLPT Load Point
Single Point Cells
Load Cell	Load Point Type, Mount Type, or Scale Type
HI SP1	HIPS Bench Scale
HI SP6	No Mount
HI SPA22	No Mount
HI SPA42	No Mount
HI SPA60	No Mount
HI SPB1	HIBS400 Bench Scale

 

Non Advantage Hardy load cells that are not FM approved need to be ordered with a "Specials" designation. All Hardy load cells ordered with the Specials designation will retain their original label, model number, serial number, and have a FM approval sticker.

The C2® data chip is NOT approved for use in hazardous areas unless it is internal to the load cell, encapsulated as a module, or is in a "Special" Load Cell. At that time, a C2® module will be made with the serial number of the load cell. This module is attached to the C2+ and C2- of the controller load cell connector. Certificates are kept on file in the Support Center Online "C2® Load Sensor Certification Retrieval Tool" at Hardy Process Solutions.
