ES-4262 Rev.9
26R1
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
