MDP-LC
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
• Absorbs surges only without affecting instrumentation signal
• No interruption of signal by unplugging the protector element
