Warranty

Each single product passes through a quality process. Nevertheless, if failures occur please contact the customer
service at once. The warranty period covers 24 months starting on the delivery date. After the warranty is expired the
manufacturer guarantees additional 6 months warranty for all repaired or substituted product components. Warranty
does not apply to damages, which result from misuse or neglect. The warranty also expires if you open the product. The
manufacturer is not liable for consequential damage or in case of a non-intended use of the product.
If a failure occurs during the warranty period the product will be replaced, calibrated or repaired without further charges.
The freight costs will be paid by the sender. The manufacturer reserves the right to exchange components of the product
instead of repairing it. If the failure results from misuse or neglect the user has to pay for the repair. In that case you may
ask for a cost estimate beforehand.

Description

The sensors of the optris CSmicro series are noncontact infrared thermometers.
They calculate the surface temperature based on the emitted infrared energy of objects [► Basics of
Infrared Thermometry].
The sensor housing of the optris CSmicro is made of stainless steel (IP65/ NEMA-4 rating) – the sensor
electronics is integrated inside the connection cable.

Read the manual carefully before the initial start-up. The producer reserves the right to change the
herein described specifications in case of technical advance of the product.

Scope of Supply

 CSmicro incl. connection cable
 Mounting nut
 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.

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.

Optical Charts

The following optical charts show the diameter of the measuring spot in dependence on the distance
between measuring object and sensing head. 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.

D = Distance from front of the sensing head to the object
S = Spot size
The D:S ratio is valid for the focus point.

LT15/ 2WLT15/ 2WLT15H/ 2WhsLT D:S = 15:1

The size of the measuring object and the optical resolution of the infrared thermometer determine the maximum
distance between sensing head 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.
