BP-LC Load cell surge protector

The BP-LC is a surge protector specially designed to protect the load cells and the mesurement instrumentation, used on weighbrige system or cranes, from possible distrubances or destructions caused by lightning transient surges.
This surge protector is based on fast clamping diodes and gas tube in order to provide powerfull and efficient protection. The diagram is chosen to suppress voltage drops and leakage currents in order to avoid loadcell calibration changes.
The BP-LC construction is completly waterproof to be used in harsh conditions as load cell installation, and it could be connected to 4 or 6 wires transmission.
