OMEGA’s 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.
