1 INTRODUCTION
1.4 OPTISONIC 3400 C(/i)-Ex
OPTISONIC 3400 
The OPTISONIC 3400 C(/i)-Ex is the compact configuration of the UFC 400 ultrasonic signal converter and the OPTISONIC 3000 ultrasonic flow sensor. It provides the ultrasonic transducers in the flow sensor with intrinsically safe (Ex ia) signals; which are only internal circuits. The flow converter is provided with increased safety (Ex e) or intrinsically safe (Ex ia) in-/outputs, indicated by an "i" in the type name and listed as OPTISONIC 3400 C/i- Ex.
The in-/outputs and mains supply connections are located in the terminal compartment, which can either be ordered as “Ex e” (default) or “Ex d” (optional). The explosion safety marking is as follows:
OPTISONIC 3400 C-Ex;
“Ex d” terminal compartment |
“Ex e” terminal compartment |
II 2 G Ex d [ia] IIC T6...T3 Gb |
II 2 G Ex d e [ia] IIC T6...T3 Gb |

|
|
1.5 OPTISONIC 3000 F/...-Ex
The OPTISONIC 3000 F/...-Ex is the remote (field) configuration of the ultrasonic flow sensor and has intrinsically safe transducer circuits. It is available in 4 versions as follows,
•Cryogenic: low temperature (LT) versions, suitable for process temperatures of -200...+180°C / -328...+356°F
•Standard versions: for process temperature of -45...+180°C / -58...+356°F
•Extra extended versions: (XXT) for process temperatures of -45...+250°C / -58...+482°F.
•High Viscosity versions (HV): for process temperatures of -45...+180°C / -58...+356°F
The normal and XXT-versions are also available as flow sensors, equiped with a closed steel circuit for hot medium (e.g. steam or hot oil), which is called heating jacket (HJ). The maximum temperature of the heating medium never exceeds the maximum permissible process temperature of 180°C (356°F) for the standard versions and 250°C (482°F) for the XXT version.
The flow sensor equipped with a heating jacket, ensures stable process temperatures.
Marking for the different flow sensor types, are listed below.
OPTISONIC 3000 F-Ex & 3000 F/HJ-Ex |
OPTISONIC 3000 F/XXT-Ex |
OPTISONIC 3000 F/LT-Ex |
OPTISONIC 3000 F/XXT/HJ-Ex |
|
|
II 2 G Ex ia IIC T6...T3 Gb |
II 2 G Ex ia IIC T6...T2 Gb |
|
|
The intrinsically safe (Ex ia) transducer circuits of the OPTISONIC 3000 F/...-Ex are connected to an associated device and have the following maximum values:
Ui = 13,1 V |
Ii = 600 mA |
Ci = 11,6 nF |
Li = 134 µH |
INFORMATION!
When thermally insulating the ultrasonic flow sensor, make sure that the temperature of the connection box does not exceed 90°C (194°F).

|
|
The intrinsically safe transducer output connections have the following values:
Uo = 8,2 V |
Io = 210 mA |
Po = 435 mW |
Co = 1,3 μF or 0,8 μF |
Lo = 0,5 mH or 1,2 mH |
