2 Channel Super-mini Signal Conditioners

with Display M1E-2 Series

THERMOCOUPLE TRANSMITTER

(2 channels, PC programmable)

Functions & Features

• Accepts direct input from a thermocouple and provides a

linearized process signal

• Wide selection of thermocouples

• 2 channels

• Adjustments with the front button

• 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
