High Speed Fibre Optic Infrared Transmitter

Omega Engineering has introduced a high speed industrial fibre optic infrared transmitter and probe system, the OS4000, which offers many new and important measurement capabilities (See Figure 1). The unit can have an optical field of view or spot size as small as 0.6mm, which is less than half the size typically available. It also has a response time as fast as
1 msec, an order of magnitude faster than similar devices.  Before we review this product, let’s review this product category and take a look at some typical applications.

Infrared Probe Devices
One of the most effective methods of making non-contact high temperature measurements in industrial applications is with a fibre optic infrared probe. These devices typically consist of a lens probe assembly which is aimed at the object to be measured, and a fibre optic interconnecting cable, which is connected to an electronics package, the transmitter, to make the temperature measurement and convert it into a useable output signal.
Let’s examine each of these components.
