1.5 OPTISONIC 3000 F/...-DIV1
The OPTISONIC 3000 F/...-DIV1 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.
The intrinsically safe transducer circuits of the OPTISONIC 3000 F/...-DIV1 are connected to an
associated device and have the following maximum values:
1.6 UFC 400 F(/i)-DIV1
The UFC 400 F(/i)-DIV1 is the remote (field) configuration of the ultrasonic signal converter and
has intrinsically safe connections to the ultrasonic flow sensor in remote design. The ultrasonic
signal converter is either provided with non-incendive or intrinsically safe signal in-/outputs
indicated by an "i" in the type name as UFC 400 F/i-DIV1. The in-/outputs and mains supply
connections are located in the terminal compartment, which can either be configured as non-
incendive (installation in a Division 2 location) or explosion-proof (installation in a Division 1)..
The hazardous locations marking is as follows:
The intrinsically safe transducer output connections have the following values:
