2. Installation
2.1 Transmitter Installation
For the installation of NCS-TT105 Intelligent temperature sensors, there are three types of mounting brackets available: tube-mounted flat bracket, tube-mounted curved bracket, and disk-mounted curved bracket. Correspondingly, there are three installation methods, namely flat bracket tube installation, curved bracket plate installation, and curved bracket tube installation. The installation methods are described below:
A typical installation of flat bracket tube installation is shown in Figure 2.1,fix the transmitter on the tube-mounted flat bracket, and then fix the tube-mounted flat bracket to the vertical tube of about Φ50mm through U-bolts.
Figure 2.2 shows the typical installation method of the curved bracket plate installation. Fix the transmitter on the panel mounting bracket, and then fix the panel mounting bracket on the dial with M10 bolts (provided by the user).
Figure 2.3&Figure 2.4 show the typical installation method of the curved bracket tube installation. Fix the transmitter on the tube mount bracket, and then fix the tube mount bracket to the horizontal pipe of about Φ50mm through U-bolts.

PA Intelligent Temperature Sensors Configuration
Topological Connection
A PROFIBUS PA network topology can have a variety of different structures, as shown in Figure 4.1Figure 4.2 shows the bus connection of the PA instrument. Both ends of the bus need to be connected to terminating resistors to ensure the quality of the bus signal. The bus has a maximum length of 1,900 m and can be extended to 10 km using a repeater.
