Lightning Surge Protectors for
Electronics Equipment M-RESTER
LIGHTNING SURGE PROTECTOR FOR RTD USE
Functions & Features
• Designed specifically for resistance temperature detector (RTD) circuits
• Protecting RTD and RTD transmitters from damage caused by surges on the RTD wiring
• Absorbs surges only without affecting instrumentation signal
• No interruption of signal by unplugging the protector element
