1. Safety
System operation assumes knowledge of the operating instructions.
1.1 Symbols Used
The following symbols are used in these operating instructions.
Indicates a hazardous situation which, if not avoided, may result in minor or moder-
ate injury.
Indicates a situation that may result in property damage if not avoided.
Indicates a user action.
iIndicates a tip for users.
Measure Indicates hardware or a software button/menu.
1.2 Warnings
Connect the power supply and the display/output device in accordance with the safety regulations for electri-
cal equipment.
> Risk of injury
> Damage to or destruction of the sensor and/or controller
Avoid shock and vibration to the sensor and the controller.
> Damage to or destruction of the sensor and/or controller
Avoid mechanical violence on the sensor.
> Damage to or destruction of the sensor
The supply voltage must not exceed the specified limits.
> Damage to or destruction of the sensor and/or controller

Safety
thermoMETER CT
Protect the sensor cable against damage.
> Destruction of the sensor, failure of the measuring device
Do not kink the sensor cable and bend the sensor cable in tight radius. The minimum bending radius is
14 mm (static). A dynamic movement is not allowed.
> Damage to the sensor cable, failure of the measuring device
No solvent-based cleaning agents may have an effect on the sensor (neither for the optics nor the housing)
> Damage to or destruction of the sensor
Avoid abrupt changes of the ambient temperature.
> Inaccurate or incorrect measurements
1.3 Notes on CE Marking
The following apply to the thermoMETER CT:
- EU Directive 2014/30/EU
- EU Directive 2011/65/EU
Products which carry the CE mark satisfy the requirements of the EU directives cited and the relevant appli-
cable harmonized European standards (EN). The measuring system is designed for use in industrial environ-
ments.
The EU Declaration of Conformity and the technical documentation are available to the responsible authori-
ties according to the EU Directives.

Laser Safety
thermoMETER CT
2. Laser Safety
The optional available laser-sighting tools (TM-LST-CT and TM-LSTOEM-CT) for thermoMETER CT, see A
1.4.4, operate with a semiconductor laser with a wavelength of 500 ... 650 nm (visible/red).
The laser fall within laser class 2 (II). The maximum optical power is ≤ 1 mW.
i
Observe the laser protection regulations.
Although the laser output is low, directly looking into the laser beam must be avoided. Close your eyes or im-
mediately turn away if the laser beam hits the eye. For repair and service purposes, the sensor must always
be sent to the manufacturer.
Lasers of class 2 (II) are not subject to notification and a laser protection officer is not required.
The following warning label must be attached to the cover (front side) of the laser-sighting tool housing:
Fig. 1 Laser warning sign and laser label
During operation of the sensor, the pertinent regulations according to IEC 60825-1 on “Safety of laser prod-
ucts” must be fully observed at all times. The sensor complies with all applicable laws for the manufacturer of
laser devices.
Laser radiation.
Irritation or injury of the
eyes possible. Close
your or immediately
turn away if the laser
beam hits the eye.

3. Technical Data
3.1 Functional Principle
The sensors of the thermoMETER CT series are non-contact measuring infrared temperature sensors. They
calculate the surface temperature based on the emitted infrared energy of objects, see 13
The sensor housing of the thermoMETER CT is made from stainless steel (protection class. IP 65/ NEMA 4),
the controller is placed in a separate box made of die casting zinc.
iThe thermoMETER CT sensor is a sensitive optical system. Please only use the thread for mechanical installation.
Avoid mechanical violence on the sensor.
