A series of fibre-optic infrared temperature sensors are for installations where traditional sensors cannot operate, such as near induction heaters, in vacuums or in high ambient temperatures.
Infrared temperature sensors work to 2500 deg C
Fibre-optic infrared temperature sensors offer a much wider temperature range, from 300 to 2500 deg C and provide a very short wavelength spectral response for measuring metallic targets.
These fibre-optic units are ideal for applications where traditional temperature sensors are unsuitable, for example near induction heaters, in vacuums or in areas with high ambient temperatures.
The temperature range of the FLA models is 300C to 1300C, an astonishing feat for a fibre-optic sensor.
This temperature range combined with their short wavelength spectral response of 1.58 to 1.8um makes the FLA units ideal for measuring metal targets, even at relatively low temperatures.
Through the USB interface and AT-301U software the temperature range, emissivity value and response time of these sensors can be configured to meet the requirements of individual applications.
This software can also provide a real-time display of the current temperature measurement of the FLA sensor, and of the maximum, minimum and average readings.
Furthermore the AT-301U software offers graph plotting functions, and can save and export measurements as text files.
These sensors use optical heads with manually adjustable focal distances to provide the best possible measurement spot size at a given distance.
Two versions are available, the LVO25 for very small measurement spots at short distances, giving a measurement spot of O1.6mm at a distance of 80mm, and the LVO35 for measurements over longer distances, which provides a measurement spot of O11mm at a distance of 1m.
These optical heads provide a white LED pilot light to show both the position and size of the measurement spot for precise alignment.
The optical head and electronics enclosures are made of stainless steel and sealed to IP65 (IP54 where the fibre-optic cable enters).
The optical head can operate in ambient temperatures up to 250C without the need for cooling.
The fibre-optic cable is protected by a stainless steel braid, with 1.5m of cable supplied as standard and up to 15m available on request.
