2.    INSTRUMENT DESCRIPTION

DESCRIPTION 

The OMX 100 model series are programmable transmitters to DIN rail manufactured in the following types:

OMX 100DC  

DC voltmeter/ammeter

OMX 100PWR 

 AC voltmeter/ammeter, wattmetr 

OMX 100PM  

Process monitor 

 

OMX 100RTD  

Thermometer for Pt 100/500/1 000, Ni 1 000

OMX 100T/C  

Thermometer for thermocouples

OMX 100DU  

Display instrument for linear potentiometers
