1.1 Intended use
This TDR level transmitter measures distance, level, mass and volume of liquids, pastes,
slurries, granulates and powders. It can also measure level and interface of liquids at the same
time.
It can be installed on tanks, silos and open pits.
1.2 Certification
In accordance with the commitment to customer service and safety, the device
described in this document meets the following safety requirements:
•Electromagnetic Compatibility (EMC) Directive 2004/108/EC in conjunction with EN 61326-1
(2006) and EN 61326-2-3 (2006).
All devices are based on the CE marking and meet the requirements of NAMUR Guideline
NE 21/07.
1.3 Electromagnetic compatibility
The device design agrees with European Standard EN 61326-1 and EN 61326-2-3 when installed
in metallic tanks.
You can install the device on open-air tanks and tanks that are not made of metal. This agrees
with Emissions requirements for industrial environments (class A). For data on Immunity
requirements, refer to the note that follows.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
CAUTION!
If you install a device with a rod or cable probe in a non-metallic tank or open-air pit, a strong
electromagnetic field near to the device can have an unwanted effect on the accuracy. Use a
device with a coaxial probe for this type of installation.
INFORMATION!
Device operation agrees with residential-class (class B) emissions and industrial-class (class A)
immunity requirements if:
• the device has a single or double probe (rod or cable probe) and is used in a closed tank made
of metal or
• the device has a coaxial probe.

2.2 Device description
The TDR level transmitter is designed to measure the distance, level, interface, mass and
volume of liquids, pastes, slurries, granulates and powders.
TDR level transmitters use a probe to guide a signal to the surface of the measured product. The
device has a large choice of probes. Thus, it can measure most products in difficult conditions.
For more data, refer to
Technical data on page 125.
The device has a set-up wizard, fully-potted electronic sub-assemblies and online help
functions. You usually will not need this document to install, set up and operate the device.
You can order these accessories:
•Stainless steel weather protection.
•RS232 / HART®converter (VIATOR).
•USB / HART®converter.
•ESD protection (30 kV).
•Metaglas®dual process sealing system for dangerous products.

1 Process connection temperature
The process connection temperature must stay in the temperature range of the gasket material unless the device is
a High-Temperature version. Refer to the table "Temperature ranges for gaskets" that follows and to "Technical data"
on page 128.
Ex devices: see supplementary operating instructions
2 Ambient temperature for operation of the display
-20...+60°C / -4...+140°F
If the ambient temperature is not between these limits, the display screen switches off automatically
3 Ambient temperature
Non-Ex devices: -40...+80°C / -40...+175°F
Ex devices: see supplementary operating instructions
4 Process pressure
Refer to the table "Process pressure limits" that follows and "Pressure/temperature table for probe selection" on
page 134.
WARNING!
The process connection temperature range must agree with the temperature limits of the
