The OMEGA®OEM style OS550A-BB series industrial,
high-performance, economical thermometer/
transmitter offers a wide choice of temperature ranges,
optical fields of view and 3 analog outputs (1 mV/ deg,
4 to 20 mA, and 0 to 5 Vdc) to feed directly into panel
meters, recorders, PLCs, temperature/ process
controllers, data loggers, data acquisition systems, or
other process instrumentation.
Since the OS550A-BB Series infrared thermometers
do not use chopper motors or vibrator mechanisms,
they can be mounted in any position and in hostile
environments without suffering any loss in
performance. This OEM design coupled with relatively
small dimensions makes these sensors ideally suited
for a wide variety of applications.
