PED approval
The thermometer complies with paragraph 3.3 of the Pressure Equipment Directive (97/23/CE) and is not
marked separately.
Material certification
The material certificate 3.1 (according to standard EN 10204) can be directly selected from the sales structure
of the product and refers to the parts of the sensor in contact with the process fluid. Other types of certificates
related to materials can be requested separately. The "short form" certificate includes a simplified declaration
with no enclosures of documents related to the materials used in the construction of the single sensor and
guarantees the traceability of the materials through the identification number of the thermometer. The data
related to the origin of the materials can subsequently be requested by the client if necessary.
Test on thermowells
Thermowell pressure tests are carried out in accordance with the specifications in the DIN 43772 standard.
With regards to thermowells with tapered or reduced tips that do not comply with this standard these are tested
using the pressure of corresponding straight thermowells. Sensors certified for use in Ex Zones, are always
tested to pressures according to the same criteria. Tests according to other specifications can be carried out on
request. Dye penetration tests verify the absence of cracks on the thermowell welding.
Test report and calibration
For the tests and calibration, the "Acceptance report" comprises a declaration of conformity with the primary
points as per IEC 60751.
The "Factory calibration" is carried out according to an internal procedure in a laboratory of Hauser
accredited by the European Accreditation Organization (EA) to ISO/IEC 17025. A calibration which is
performed according to EA guidelines (SIT or DKD calibration) may be requested separately. The calibration is
performed on the replaceable insert of the thermometer. In the case of thermometers without a replaceable
insert, the entire thermometer - from the process connection to the tip of the thermometer - is calibrated.
