The OMEGA OS555A Series
industrial high performance
thermometer/transmitters offer a high
temperature range of 538 to 2482ºC
(1000 to 4500ºF), 110 to 1 optical field
of view, any voltage or current analog
output to feed directly to panel
meters, recorders, temperature/
process controllers, data loggers, and
data acquisition systems. It also
offers adjustable Emissivity, high and
low alarm outputs, PC serial
interface, temperature data logging in
real-time, and fast response time of
These ruggedly designed units are
ideal for high temperature
measurement and see through
glass window applications.
