Description
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 [► Basics of
Infrared Thermometry]. The alignment of the sensor can be done with the integrated video sighting and
crosshair laser aiming.
The sensor housing of the CTVideo sensor is made of stainless steel (IP 65/ NEMA-4 rating) –the sensor
electronics is placed in a separate box made of die casting zinc.
Scope of Supply
CTVideo sensor with connection cable and controller
Mounting nut and mounting bracket (fixed)
5 m USB cable (outgoing from the controller)
Software
Operators manual
Maintenance
Lens cleaning: Blow off loose particles using clean
compressed air. The lens surface can be cleaned with a
soft, humid tissue moistened with water or a water based
glass cleaner.
The CTVideo sensor is a sensitive optical system. Please use only the thread for mechanical installation.
Avoid mechanical violence on the head –this may destroy the system (expiry of warranty).

Cautions
Avoid abrupt changes of the ambient temperature.
In case of problems or questions which may arise when you use the CTVideo, please contact our service
department.

Optical Charts
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 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.
The size of the measuring object and the optical resolution of the infrared thermometer determine the maximum
distance between sensor and measuring object.
In order to prevent measuring errors the object should fill out the field of view of the optics completely.
Consequently, the spot should at all times have at least the same size like the object or should be smaller than
that.
