OMEGA’s OS100E Series miniature infrared sensors/transmitters measure a temperature range of -18 to 538°C (0 to 1000°F). They consist of a remotely mounted infrared sensor head connected to a high-performance, microprocessor-based signal conditioner. The miniature sensor head is ideal for measuring temperature in confined, hard-to-reach places and harsh environments. The sensor head is connected to the main electronics housing via a 1.8 m (6') shielded cable. The signal conditioner’s main electronics are mounted in a rugged NEMA 4 (IP65) rated die-cast aluminum housing. Model OS102E includes a built-in LED display that is switchable between °C and °F. Standard features include adjustable emissivity, field-adjustable alarm output, and RS232 PC interface. The unit has analog outputs such as 4 to 20 mA, 0/5 Vdc, 0/10 Vdc, 1 mV/degree, and Type K thermocouple.

Adjustable emissivity from 0.1 to 1 makes the OS100E Series suitable for a wide variety of different material surfaces. Applications such as asphalt, brass, brick, paints/lacquers and much more can be measured. Thermocouple outputs allow for easy convenient replacement of thermocouple contact sensors and don’t require external power source.

The manual refers to a serial bus interface and an installation of the software with a CD. Is an interface with a USB available ? Also is an alternative emthod of installing the associated software available ?

Asked by: Flyingcar1
Thank you for the inquiry. You would need to use an RS232 to USB adapter. Software can be downloaded from this product page under "Manuals and Downloads". We do not currently offer the RS232 to USB adapter for this model. Best regards OMEGA
