Rail
1. INTRODUCTION
Universal head transmitter is used for resistance thermometers (RTD)
, thermocouples
(TC), resistance and voltage transmitter, settable via HART-protocol. The slim housing with
12.5mm wide is used for DIN-rail mounting. Temperature Transmitter with HART-protocol is
mostly applicable in the areas for converting input signals into a scalable 4~20 mA analogue
output signal.
2. PRESENTATION
2.1 Features
