M2EXT  Super-mini Signal Conditioners with
Display Mini-M M2E Series

THERMOCOUPLE TRANSMITTER
(PC programmable)

Functions & Features
• Accepts direct input from a thermocouple and provides a linearized process signal
• Adjustments with the front button
• Wide selection of thermocouples
• OEL display with good visibility
Typical Applications
• Small burnout sensing current enables long distance transmission with minimum offset drifts
• Electric furnace (isolation)
• No burnout type can connect to a single T/C in parallel with a recorder
