The supply voltage must not exceed the specified limits.
> Damage to or destruction of the sensor and/or controller
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 static electricity and keep away from very strong EMF (electromagnetic fields) e.g. arc welders or
induction heaters.
> Damage to or destruction of the sensor

- EU Directive 2004/108/EU
- EU Directive 2011/65/EU, “RoHS”, category 9
Products which carry the CE mark satisfy the requirements of the EU directives cited and the European
harmonized standards (EN) listed therein. The EU Declaration of conformity is available to the responsible
authorities according to the EU Directive, article 10, at:
MICRO-EPSILON MESSTECHNIK
GmbH & Co. KG
Koenigbacher Str. 15
94496 Ortenburg / Germany
The measuring system is designed for use in industrial environments and meets the requirements.

thermoMETER CTL
1.4 Intended Use
- The thermoMETER CTL is designed for use in industrial and laboratory areas. It is used for non-contact
temperature measurement.
- The system must only be operated within the limits specified in the technical data, see 3.
- The system must be used in such a way that no persons are endangered or machines and other material
goods are damaged in the event of malfunction or total failure of the sensor.
- Take additional precautions for safety and damage prevention in case of for safety-related applications.
1.5 Proper Environment
- Protection class:
Sensor: IP 65 (NEMA 4)
Controller: IP 65 (NEMA 4)
- Ambient temperature:
Sensor 1: -20 ... +85 °C (-4 ... +185 °F), see also Chapter Measurement
Specification, see 3.3
Controller 2: 20 ... +85 °C (-4 ... +185 °F), see also Chapter Measurement
Specification, see 3.3
Avoid abrupt changes of the ambient temperature of both the sensor and the controller.
> Inaccurate measuring values
- Storage temperature:
Sensor: See also Chapter Measurement Specification, see 3.3
Controller: -40 ... +85 °C (-40 ... +185 °F)
- Humidity: 10 ... +95 %, non-condensing
1) The sensor can be used at ambient temperatures up to +85 °C without cooling. For applications, where
the ambient temperature can reach higher values, the usage of the optional water cooled housing, see Chap.
A 1.3, is recommended (ambient temperature up to +175 °C). The sensor should be equipped with the op-
tional high temperature cable (ambient temperature up to +180 °C), see A 1.4
2) With temperatures < 0 °C (+32 °F), display function is not guaranteed any more.

Laser Safety
thermoMETER CTL
2. Laser Safety
The thermoMETER CTL sensors operate with a double laser sight with a wavelength of 635 nm (visible/red),
see 9.4. The sensors 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
immediately turn away if the laser beam hits the eye. The housing of the optical sensors may only be opened
by the manufacturer, see 15. For repair and service purposes, the sensor must always be sent to the manu-
facturer.
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 controller housing.

3. Technical Data
3.1 Functional Principle
The sensors of the thermoMETER CTL series are non-contact measuring infrared temperature sensors. They
calculate the surface temperature based on the emitted infrared energy of objects, see Chap. 12. An inte-
grated double laser aiming marks the real measurement spot location and spot size at any distance on the
object surface.
The sensor housing of the thermoMETER CTL is made from stainless steel (protection class IP 65/ NEMA 4),
the controller is placed in a separate box made of die casting zinc.
i
The thermoMETER CTL sensor is a sensitive optical system. Please only use the thread for mechanical
installation.
Avoid mechanical violence on the sensor.
