Head-mounted Two-wire Signal Conditioners

26-UNIT

RTD TRANSMITTER

(non-isolated)

Functions & Features

• Accepts direct input from an RTD and provides

a standard 4 – 20 mA DC signal

• Linearization and burnout

• Wide operating temperature range suitable for

harsh environments

Typical Applications

• Mounting in a sensor connection head minimizes noise

effect and signal degradation
