Description
1Description
The sensors of the CSmicro series are noncontact infrared temperature sensors.
They calculate the surface temperature based on the emitted infrared energy of objects [►Basics of
Infrared Thermometry].
The sensor housing of the CSmicro is made of stainless steel (IP 65/ NEMA-4 rating) – the sensor
electronics is integrated inside the connection cable.
1.1 Scope of Supply

Mounting nut
Operators manual
1.2 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.
PLEASE NOTE: Never use cleaning
compounds which contain solvents
(neither for the lens nor for the housing).

Description
1.3 Cautions
Avoid abrupt changes of the ambient temperature.
In case of problems or questions which may arise when you use the sensor, please contact our service
department.
The sensors CSmicro are sensitive optical systems. Please use only the thread for mechanical
installation.
Avoid mechanical violence on the sensor – this may destroy the system (expiry of warranty).

Technical Data
2.6 Optical Charts
The following optical charts show the diameter of the measuring spot in dependence on the distance
between measuring object and sensor. The spot size refers to 90 % of the radiation energy.
The distance is always measured from the front edge of the sensor housing/ CF-lens holder/ air purge.
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.

2.7 CF Lens and Protective Window
If the CF lens is used, the
transmission has to be set to 0.78
[
SF
15/ 2W/
HS
].
The optional CF lens allows the measurement of very small
objects. The minimum spot size depends on the used sensor. The
distance is always measured from the front edge of the CF lens
holder or laminar air purge collar. The installation on the sensor
will be done by turning the CF lens until end stop. To combine it with the HS model please use the
version with external thread M12x1.
Versions Overview:
TM-CF-CS CF lens for installation on sensor [SF15/ 2W/ HS]
TM-CFH-CS CF lens for installation on sensor [2WM-2]
TM-CFAG-CS CF lens with external thread for installation in massive housing [SF15/ 2W/ HS]
TM-CFHAG-CS CF lens with external thread for installation in massive housing [2WM-2]
For protection of the sensor optics a protective window is available. The mechanical dimensions are equal
to the CF lens. It is available in the following versions:
TM-PW-CS Protective window for installation on sensor [SF15/ 2W/ HS]
TM-PWH-CS Protective window for installation on sensor [2WM-2]
TM-PWAG-CS Protective window with external thread for installation in massive housing [SF15/ 2W/ HS]
TM-PWHAG-CSProtective window with external thread for installation in massive housing [2WM-2]
If the protective window is used, the transmission has to be set to 0.83 [SF15/ 2W/ HS] or 0.93

3.1 Mechanical Installation
The CSmicro is equipped with a metric M12x1 thread and can be installed either directly via the sensor
thread or with the help of the hex nut (standard) to the mounting bracket available. The CSmicro HS will
be delivered with the massive housing and can be installed via the M18x1-thread.
The sensors CSmicro are sensitive optical systems. Please use only the thread for mechanical
installation. Avoid mechanical violence on the sensor
