DIMENSIONS in millimeters
PRODUCTION
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A
homogeneous film of platinum is deposited on a high grade
ceramic body (96 % AI2O3). The sensor-elements are
covered by a protective coating designed for electrical,
mechanical and climatic protection.
QUALITY
The result of the determined production is verified by an
extensive testing procedure performed on 100 % of the
individual sensors. Only accepted products are laid directly
into the waffle trays. The resistance values and tolerances
according to DIN EN 60751 are given for the device including
the standard leads. Any additional wiring will change
resistance values for the total setup.
ASSEMBLY
The Pt-sensors are suitable for all standard assembly
processes like crimping, soldering, brazing and welding
(LASER- or resistive welding).
The parameters of the assembly process should be chosen
in accordance with the used wire material. It is
recommended to verify the parameters by pre-testing.
The assembly process of the sensor should be in compliance
with the following guidelines and recommendations:
Fixation of only one lead during assembly
Tensile forces parallel to the leads < 5 N
Avoiding of large temperature gradients between the
welding region and the sensor during assembly, e.g. by
using a cooled clamp with a good thermal conductivity
Radius of curvature of the leads > 0.3 mm
Curvature or torsion strain > 3 mm away form the sensor
element
After assembly we recommend to fix the leads in the
welded region with a strain relief
ENVIRONMENTAL CONDITIONS
Unprotected sensor-elements are usable under dry
environmental conditions only. Platinum-plated nickel leads
enable the usage in applications with ambient temperatures
up to 550 °C. The environment of the sensor application
should be without any corrosive substances (e.g. potassium
hydroxide or hydrogen fluoride) or other contaminants which
could affect the sensor, especially shifting the temperature
coefficient of the sensor. This has also to be considered
during the assembly process.
DIRECTIVES
All products comply with the CEFIC-EECA-EICTA list of legal
restrictions on hazardous substances.
This includes full compatibility with the following directives:
2000/53/EC End of Vehicle Life Directive (ELV)
2000/53/EC Annex II to End of Vehicle Life Directive
(ELV II)
2002/95/EC Restriction of the use of Hazardous
Substances Directive (RoHS)
2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
APPROVALS
The Pt-sensors are tested in accordance with IEC 60751/
DIN EN 60751.
