Explosion-proof Device Manual EN.IX.SGE.25.SMART
1. Introduction
Explosion-proof Device Manual EN.IX.SGE.25.SMART only applies to smart level probes:
SGE–25.Smart, SGE–25S.Smart, SGE–25C.Smart in intrinsically safe version with marking as a point
2 on the nameplate and the Ex version in the Product Certificate. When installing and using probes in
User's
Ex
version,
EN.IX.SGE.25.SMART must be used.
2. Using probes in hazardous area
The probes are produced in accordance with the requirements of the following standards:
EN IEC 60079-0:2018-03+A11:2014-03; EN 50303:2004; EN 60079-11:2012.
The probes may operate in areas where there is a risk of explosion , in accordance with the rating of
the explosion protection design:
3. Permissible input parameters (based on data from certificate
KDB 11ATEX140X)
-
The probes should be powered from co-operating power supply and measuring
equipment with relevant intrinsic-safety certificates, whose parameters for output to the
danger zone should not exceed the permissible power supply parameters for the
probes given in points a) and b).
-
Probes in "SA version" should be powered from devices with galvanically separated
power supply.
-
The probe is an intrinsically safe device with protection level "ia" when the supply circuit
has protection level "ia" or an intrinsically safe device with protection level "ib" when the
supply circuit has protection level "ib".
a)
Permissible
Ui = 30 V DC; Ii = 0,1 A
b)
Permissible input parameters for power supply with trapezoidal and rectangular characteristic:
Ui = 24 V DC; Ii = 0,1 A
Input capacitance and inductance: Ci = 11 nF*; Li = 0,611 mH*
*) Consider the cable capacitance and inductance, which for a permanently connected cable are:
Ck= 0.2 nF/m i Lk=1 µH/m.
Input capacity Cw and inductance Lw taking into account the parameters of a permanently connected
cable is: Cw = Ci + a x Ck = 11nF + a x 0.2 nF/m; Lw= Li + a x Lk = 0,61 mH + a x 1 µH/m
where: - a - length of the wire permanently installed in the probe in metres.
