© Siemens AG 2016 Temperature Measurement Transmitters for field mounting SITRANS TF280 WirelessHART ■ Overview ■ Application The SITRANS TF280 is a WirelessHART field device for temperature measurement with a Pt100 sensor. This sensor can be installed directly on the field device, or connected at an offset with a cable connection. On the wireless communication side, the transmitter supports the WirelessHART standard. A HART modem can be connected to the transmitter particularly for initial parameterization. Alternatively the device can be commissioned comfortably by means of the local pushbuttons w/o any additional handset devices. 2 It can be used in all industries and applications in non-explosive areas. ■ Design The SITRANS TF280 has a robust aluminum enclosure and is suitable for outside use. It conforms with the IP65 safety class. SITRANS TF280 for flexible and cost-effective temperature measurements • Supports the WirelessHART standard (HART V 7.1) • Very high security level for wireless data transmission • Built-in local user interface (LUI) with 3-button operation • Optimum representation and readability using graphical display (104 x 80 pixels) with integrated backlight • Stand-by (deep sleep phase) mode can be turned on and off with push of a button • Battery power supply • Battery life time up to 5 years • Extend battery life time with HART modem interface which can be switch off • Optimized power consumption through new design, and increase in battery life time • Simple configuration thanks to SIMATIC PDM • Housing meets IP65 degree of protection • Supports all Pt100 sensors as per IEC 751/DIN EN 60751 ■ Benefits The SITRANS TF280 is a temperature transmitter that features WirelessHART as the standard communication interface. Also available is a wired interface to connect a HART modem: • Flexible temperature measurement • Save costs on wiring at difficult installation conditions. Wireless technology offers cost advantages in cases where extensive wiring costs would normally apply. • It enables additional hitherto unfeasible measuring points, particularly for monitoring purposes • Easy installation also on moveable equipment parts • Enables cost-effective temporary measurements, for example for process optimizations. • Optimum solution in addition to wired communication and for system solutions in process automation The operation temperature range is -40 to +80 °C (-40 to +176 °F). Power supply is provided through an integrated battery, which is available as an accessory. The device is only approved for operation with this battery. The antenna features a rotatable joint which can be used for directional alignment. Wireless signals can thus be optimally received and transmitted. A special highlight is the possibility to operate directly on the device with 3 push buttons. It perfectly matches the strategy of all new Siemens field devices. Using the device’s push buttons, it is easy to turn the HART modem interface of the device on and off. The device can be put to passive status and reactivated at any time. This helps to extend the life time of the battery. The SITRANS TF280 transmitter features a cable gland or a Pt100 sensor including protective piping. ■ Function The SITRANS TF280 can join to a WirelessHART network. It can be parameterized and operated through this network. Measured process values are transmitted via the network to the SIEMENS IE/WSN-PA LINK. Field device data received by the IE/WSN-PA LINK is transmitted to the connected systems, for example the process control system SIMATIC PCS 7. For an introduction of WirelessHART, please see the FI 01 catalogue Sec. 8 or www.siemens.com/wirelesshart. Detailed information on IE/WSN-PA LINK can be found in the FI 01 catalogue Sec. 7 or www.siemens.com/wirelesshart. ■ Integration Connecting to SIMATIC PCS 7 The integration of field devices in SIMATIC PCS 7 and other process control systems can be now done seamlessly and cost-effectively with wireless technology, especially in situations where high wiring costs may be expected. Of particular interest are measuring points which are to be added and for which no wiring is available. Where larger distances between the IE/WSN-PA LINK and control systems need to be overcome, this connection can also be implemented on a wireless and cost-effective basis using the SCALANCE W series of products. Siemens WirelessHART devices operate with optimum coexistence to SCALANCE W family products. 2/166 Siemens FI 01 · 2016 © Siemens AG 2016 Temperature Measurement Transmitters for field mounting SITRANS TF280 WirelessHART ■ Technical specifications ES OS MS Industrial Ethernet SITRANS AW210 SIMATIC system SITRANS AW200 The SITRANS TF280 can be mechanically installed in two ways: • Direct at the measuring point with a M20x1.5 thread. A connection to other threads can be done via the adapter. • Remotely from the Pt100 sensor, which is connected to the transmitter via a cable. The data in the following table refer to the transmitter only excluding a connected sensor, except as noted otherwise.
