M2XT2

Super-mini Signal Conditioners Mini-M Series

THERMOCOUPLE TRANSMITTER

(PC programmable)
Functions & Features
• Accepts direct input from a thermocouple and provides a linearized process signal
• PC programmable
• Wide selection of thermocouples
• User’s temperature table can be used
• Leadwire resistance compensation
Typical Applications
• Small burnout sensing current enables long distance transmission with minimum offset drifts
• Electric furnace (isolation ensured even when 200 V AC power for heater leaks through furnace wall)
• No burnout type can connect to a single T/C in parallel with a recorder
• Ideal for quick spare part
