HYDROSTATIC LEVEL PROBES type: SGE–25, SGE–25S, SGE–25C
1.
Introduction
1.1 This "Appendix Ex.04" applies only to hydrostatic level probes SGE-25, SGE-25C and SGE-25S in Ex
versions, marked on the rating plate as shown in 2.2 and denoted Ex in the Product Certificate.
1.2 The appendix contains supplementary information relating to the Ex versions of the SGE–25, SGE–25C,
SGE–25S probes. During installation and use of Ex probes reference should be made to DTR.SG...04 in
conjunction with "Appendix Ex.04".
2. Use of probes in danger zones
2.1. The probes SGE–25, SGE–25S are produced in accordance with the requirements of the following
standards: EN 60079-0:2006, EN 50303:2004, EN 60079-26:2007, EN 60079-11:2007
2.2. The probes may operate in areas where there is a risk of explosion, in accordance with the rating
of the explosion protection design:
II 1G
Ga Ex ia IIC T4/T5/T6
I M1 Ex ia I
KDB 09ATEX007
3. Identifying marks
The above mentioned probes in Ex-version , must have a rating plate containing the information specified in
paragraph 4 of DTR. SG...04, and also at least the following:
-
CE mark and number of notified unit: 1453 in the case of GIG KDB,
-
designation of explosion protection design, certificate number,
-
values of parameters such as Ui, Ii, Ci,
-
year of manufacture
4. User information.
Together with the probes ordered, the user will receive: User's Manual numbered DTR.SG...04
with Appendix Ex.04, and also the Product Certificate.
5. Permitted input parameters of the SGE–25, SGE–25S, SGE–25C probes
(based on data from the KDB 09ATEX007 certificates, and certification
documentation.)
-permitted input parameters for power supply with a linear characteristic.
Ui = 28V DC Ii = 0,1A
-permitted input parameters for power supply with a "rectangular" characteristic and "trapezoidal"
characteristic
Ui = 28V DC Ii = 0,08A
