Lightning Surge Protectors for

Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR

STRAIN GAUGE USE

Functions & Features

• Designed to protect strain gauge transmitters from

lightning surge damage that enters on the wiring between

the strain gauge and the transmitter

• Absorbing surges only without affecting instrumentation

signal

• Shallow depth

• DIN rail mounting
