Legal information
Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

3.4 Mode of operation
SITRANS TF280 WirelessHART
Operating Instructions, 10/2010, A5E02619566-02 15
3.4 Mode of operation
Measuring principle
The device contains a Pt100 sensor element (resistance thermometer) in accordance with
IEC 751/DIN EN 60751. The temperature is measured as a change in resistance. This signal
is amplified by the measuring amplifier and digitized in an analog-to-digital converter.
The digital signal is analyzed in a microcontroller and corrected with regard to linearity.
The measured value is then available to a HART master via HART FSK as well as wireless
HART.
The sensor-specific calibration data are stored in an EEPROM.
3.5 Sensor
Properties
SITRANS TF280 WirelessHART applies Pt100 resistance thermometers of Class A or B.
The sensor elements used correspond to IEC 60751 and exhibit the following properties:
● Exchangeable sense element: The terminal is located in the device housing next to the
battery clips.
● Maximum length of sensor cable: 3 m with 2-, 3- or 4-wire connection.
● Software-based detection of sensor breaks.
● Measurement in temperature range -200 °C to +850 °C.
You can find additional information on the sensor elements under Technical data (Page 85).

3.6 Battery
The very low energy consumption of the device means that a battery service life of up to
5 years is possible. The current charging level of the battery is shown in the device's digital
display. If a critical charging level is reached, the device also sends this condition as part of
the "Extended Status Byte" to the host control system.
Other repair or maintenance measures are not required on the device. You can find
supplementary information on this under Inserting / removing the battery (Page 28) and
Alarm, error, and system messages (Page 79).

Frequency band 2.4 GHz
Data transmission Frequency spread procedure (per packet basis)
Transmission range Up to 250 m (visual connection)
Power supply Battery

Star topology
Combination of both topologies
HART specification HART protocol V7.1
HART - IEC 61158 E DDL - IEC 61804-3
3.7.2 WirelessHART
Fundamentals
Wireless HART is a fieldbus standard of the HART Communication Foundation and permits
radio-based networking of field devices.
The radio transmission is based on the wireless communication standard
IEEE 802.15.4-2006 (ISM band, 2.4 GHz).
The data transmission is appropriately encrypted using the
Advanced Encryption Standard (AES 128). Data transmission as well as parameterization of
the field devices involved is thus protected.
The data transmission is coordinated by the TDMA procedure
(Time Division Multiplex Access). Signals from different transmitters are then only
transmitted on the common bus within specific time slots, or the radio stations are
synchronized with a sampling rate of 10 ms.
Interferences from other radio stations also using the 2.4 GHz band are minimized by
application of a frequency spread procedure.

SITRANS TF280 WirelessHART
18 Operating Instructions, 10/2010, A5E02619566-02
Properties
Field devices communicating using wireless HART can be connected into a meshed
network:
● The wireless HART gateway obtains information from each field device involved in the
wireless HART network concerning the respective adjacent devices.
● The network manager in the wireless HART gateway organizes the network on the basis
of this information.
The field devices present on the network are both signal sources and repeaters. A message
is passed on from the transmitting field device via the connected fields devices until the
wireless HART gateway is reached. If a network station fails or if a hindrance prevents a
message from being passed on, the data is automatically transmitted via alternative routes.
If an additional field device is integrated into an existing network, it must be authenticated.

The transmission distance from station to station without barriers (line-of-sight) is up to
250 m. Significantly longer distances can be covered it the field devices of a network are
spatially positioned in sequence.
