OPTIBAR 5060
www.krohne.com 04/2014 - 4003591801 - AD OPTIBAR 5060 Ex ia R01 en
OPTIBAR * 5060 VGK5/6/D*A/W C/U/0/H/T with integrated electronics Z (4…20 mA),
H (4…20 mA/HART) or A (4…20 mA/HART with SIL qualification), version with double chamber
housing D, W or R with housing version/protection category P (with M12 x 1)
Circuit for the display and adjustment
module: (spring contacts in the "Ex-i"
terminal compartment)
in protection type intrinsic safety Ex ia IIC
Only for connection to the display and adjustment module.
In the double chamber housing version, the display and
adjustment module in the terminal compartment should only
be equipped if there is no OPTIBAR * 5060 with electronics S, T
connected.
Circuit between sensor and external
electronics
in protection type intrinsic safety Ex ia IIC
For the OPTIBAR * 5060 VGK5/6/D*A/W C in the version with
the cable permanently mounted to the sensor and external
electronics, the length of the supplied cable between the
external housing and the sensor should not exceed 180 m and
for the OPTIBAR * 5060 VGK5/6/D*A/W C with external
housing it should not exceed 50 m.
OPTIBAR * 5060 VGK5/6/D*A/W C/U/0/H/T with integrated electronics S or T, only single
chamber housing version)
Supply and signal circuit: (terminals
5,6,7,8 in the electronics compartment)
in protection type intrinsic safety Ex ia IIC
For connection to the intrinsically safe circuit of an OPTIBAR *
5060 VGK5/6/D**C with integrated electronics H, A, P, F for
differential pressure measurement.
The rules for interconnecting intrinsically safe circuits
between OPTIBAR * 5060 with electronics S or T and the
OPTIBAR * 5060 VGK5/6/D**C are observed when the overall
inductance and overall capacity of the connecting cable

OPTIBAR * 5060 VGK5/6/D*A/W C/U/0/H/T version with separate cable outlet
Circuit between sensor unit and
external electronics (terminal 1 - yellow,
terminal 2 - white, terminal 3 - red,
terminal 4 - black)
in protection type intrinsic safety Ex ia IIC
For the OPTIBAR * 5060 VGK5/6/D*A/W C/U/0/H/T in the
version with the cable permanently mounted to the sensor
unit and external electronics, the length of the supplied cable
between the external housing and the sensor unit should not
exceed 180 m.
