The OMEGA® PRS-S-TMM12 
Series probes are identical to the 
PRS-S-M12 probes except for the 
addition of a built-in 4 to 20 mA 
transmitter inside the housing.  
This eliminates the need for a 
separate transmitter when a  
4 to 20 mA signal is required for 
your instrumentation. The housing  
cover is removable, allowing for 
adjustment of the transmitters zero 
and span settings.
