Omega Engineering”s OS4000 Series of industrial high-speed fiber optic infrared transmitters are capable of measuring temperature from 200 C to 1,600 C (392 F to 2,912 F) using three standard optical fields of view and three standard fiber-optic cable lengths. This CE-compliant product has a response time of one millisecond and adjustable emissivity from .05 to .99. Other standard features include built-in laser sighting for lens probe positioning, linear analog output (1 mV/ Deg, 0/5 VDC, 0/10 VDC, or 4-20 mA), high and low alarm outputs, fiber-optic gain adjust, maximum & minimum temperature measurement, RS232 interface, and a Windows-based PC interface software to allow changing response time, high & low alarm set points, and data logging. Transmitter mounting bracket and mounting nuts are included. Water cool jacket, vacuum bushing, air purge collar and mounting bracket for the fiber optic lens probe are all optional accessories. Optional two relays with contact closure outputs and custom optical field of views and temperature ranges are available. The transmitter is a good fit for semiconductor, petrochemical, steel and plastic industries. Recommended applications are induction heating, vacuum chamber, metal processing and power generation.
