M2TT  Signal Conditioners Mini-M Series

THERMOCOUPLE TRANSMITTER
(photovoltaic system, instrument shelter)

Functions & Features
• Accepts direct input from a thermocouple and provides a standard process signal
• Burnout
• High-accuracy cold junction compensation
• Fast response type available
Typical Applications
• High-accuracy cold junction compensation benefits narrow span measurements
• 0.1 μA burnout sensing enables long distance transmission with minimum offset drifts
• No burnout type can connect to a single T/C in parallel with a recorder
