The TX94A-SS temperature
transmitters are high performance
stainless steel industrial transmitters
designed for direct connection to
most CIP (clean-in-place) sanitary
Pt100 probes that incorporate an
M12 style connection. Available
in four temperature ranges, the
TX94A-SS has a standard
4 to 20 mA output signal.
