®
accept all the
mentioned process connections.
Ex approval
ATEX certificate KEMA 01 ATEX1169 X (1 or 1/2 GD IIC EEx ia T6...T1 T85...450°C) for TR 45.
Material certification
The 3.1.B material certificate, according to standard EN 10204, is selectable directly from the sale structure of
the product. Other types of material certifications can be requested separately.
The "standard" one is a simplified and cost-effective version, in which the documentation about the origin of
the materials employed refers to each sensor. The "labelled" version also has a specific marking that relates to
the wetted parts of the sensor and ensures that the relevant data are placed in the archives by means of the
serial number of the thermometer.
Test report & calibration
Regarding testing and calibration, the "inspection test report" consists of a declaration of conformity with the
essential points of standard DIN EN 60751.
The "Factory calibration" is carried out in the E+H EA (European Accreditation) accredited laboratory for tem-
perature calibrations, following an internal procedure. A calibration performed according to an EA accredited
procedure (SIT calibration) may be requested separately.
The calibration is executed on the thermometer insert, when that has been installed in the sensor (TR 45).
For TR 44 a minimum immersion length (120 mm) is required to ensure a precise calibration.
With the Sensor Matching Calibration, a preliminary Factory calibration of the sensor is carried out and subse-
quently the output curve of the transmitter is adjusted in order to minimize measurement error. In this way
some of the sensor errors (probe or "loop" probe+transmitter) are compensated for through the transmitter.
Further details
Maintenance
Omnigrad M thermometers do not require specific maintenance. For the models supplied with process con-
nections including seals, the integrity of the sealing ring should be checked regularly and it must be substituted
when necessary.
In case of ATEX-certified components (transmitter, insert), please refer to the relevant documentation (see the
code at the end of this document).
Delivery time
For small quantities (about 10 units) and standard options, generally 10 days.
