The new Convir FL series of fibre-optic infrared temperature sensors are ideal for installations where traditional sensors cannot operate, for example near induction heaters, in vacuums or in areas with high ambient temperatures.

The FL series sensors can measure temperatures from 400șC to 1200șC, with adjustable emissivity and an ultra fast response time of just 1ms.

Two optical heads are available; the LVO25 is designed for use over short distances with very small spot sizes, and the LVO35 head is intended for longer distance measurements. Both of these optical heads use a manually adjustable focal distance to help provide the best possible measurement spot size at any distance. A white LED light can be shone through the lens of either sensing head showing the area being measured to help with precise alignment and focusing.

The sensing heads of the FL series sensors can operate in ambient temperatures up to 250șC without the need for additional cooling.

The emissivity setting of the FL models can be quickly and easily changed using a simple rotary switch on the rear of the instrument. This adds extra flexibility to the FL models, allowing them to measure most materials and eliminating the need to remove them from service to configure them for new target materials.
