2. Technical Data
2.1 Functional Principle
The sensors of the thermometer CTVideo series are noncontact infrared temperature sensors.
They calculate the surface temperature based on the emitted infrared energy of objects, see Chap. 12.5. The
alignment of the sensor can be done with the integrated video sighting and crosshair laser aiming.
The sensor housing of the thermometer CTVideo sensor is made of stainless steel (IP 65/ NEMA-4 rating) –
the controller is placed in a separate box made of die casting zinc.
iThe thermometer CTVideo sensor is a sensitive optical system. Please use only the thread for mechani-
cal installation.
Avoid mechanical violence on the sensor.

4. Optics
The vario optics of the CTVideo allows a smooth focusing of the optics to the desired distance. The sensors
are available in two optic versions:
Optics Focus adjustable in the range
SF 200 mm til infinity
CF 90 mm til 250 mm
The size of the measuring object and the optical resolution of the infrared thermometer determine the maxi-
mum distance between sensor and measuring object.
Avoid that the measurement object fills the field of optics completely.
> Measurement error
Consequently, the spot should at all times have at least the same size like the object or should be smaller
than that. The following tables show the diameter of the measuring spot for some selected distances. The
spot size refers to 90 % of the radiation energy.
The distance is always measured from the front edge of the sensor.
