Load Cell Protectors

The Gatekeeper GKLCP has been developed to offer over-voltage protection to sensitive strain gauge based load cells and signal conditioners. It is configured to provide voltage clamping across the strain gauge outputs as well as the excitation voltage from the signal conditioner. A low capacitance connection to earth helps to avoid earth loops, whilst providing a reliable current path under transient conditions.


The ILC36V load cell surge protector is designed for use with load cells using four wire or six wire connections to a strain gauge bridge. It is installed in series with the line to be protected.
