Description FTK9 series infrared thermometers employ fiber optic cable
designed for precise non-contact temperature measurement of otherwise
inaccessible or moving targets. Thermometer consists of a remote sensor
head, fiber optic cable and a converter unit. Infrared energy of the
target is passed on from the lens to the converter unit through a fiber
optic cable. The converter unit converts infrared energy into linear
analog output signal for convenient display or recording by external
devices like temperature indicator, controller, recorder or PLC. Analog
output scaling is possible. Optional computer interface is available.
Single point alarm output is provided.
Thermometer is equipped with a LED guide light for aiming at the target and for indication of the target spot size. It is also equipped with peak hold and smoothing function. |

Reflection correction function is available in
case of error caused by target surface is reflecting any external energy. Sensor head and fiber optic cable can withstand ambient
temperature up to 150°C allowing close access to target for precise
temperature measurement under harsh environmental conditions. Length of
the fiber optic cable can be chosen to keep the converter unit safely away
from extreme environment. Converter unit also has robust design and work
well at ambient temperature of up to 70°C.
Parameter setting unit Various measurement parameters of thermometers such
as emissivity correction, temperature measurement mode, measuring range,
analog output scaling, alarm point and response time can be programmed
into the converter unit using parameter setting unit. |
