Space-saving Plug-in Signal Conditioners H-UNIT

THERMOCOUPLE TRANSMITTER

(field-programmable)

Functions & Features

• Accepting direct input from a thermocouple and providing

a standard process signal

• Micro-processor based

• Field-programmable T/C type and temperature range

• Linearization

• Burnout protection

• High accuracy cold junction compensation

• Loop testing via hand-held programmer PU-2x

• High-density mounting

Typical Applications

• Ideal for quick spare part

• High-accuracy cold junction compensation benefits narrow

span measurements

• 0.1 μA burnout sensing enables long distance

transmission with minimum offset drifts

• Electric furnace (isolation)

• No burnout type can connect to a single T/C in parallel

with recorder
