© Siemens AG 2015 Pressure Measurement Transmitters with WirelessHART SITRANS P280 for gauge and absolute pressure ■ Overview ■ Application The SITRANS P280 is a WirelessHART field device for measuring absolute and gauge pressure. The measuring ranges for absolute and gauge pressure measurements are 0 to 1.6, 10, 50, 200 and 320 bar (0 to 23, 145, 725, 2900 and 4641 psi). The sensor is integrated into the transmitter housing. On the wireless communication side, the transmitter supports the WirelessHART standard. A HART modem can be connected to the transmitter particularly for initial comissioning, alternatively the device can be commissioned comfortably by means of the local pushbuttons w/o any additional handset devices. It can be used in all industries and applications in non-explosive areas. ■ Design The SITRANS P280 has a robust aluminum enclosure and is suitable for outside use. It conforms with the IP65 safety class. The operating 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. SITRANS P280 for flexible and cost-effective applications in pressure monitoring • 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 display and readability using graphical display (104 x 80 pixels) with integrated backlight • Stand-by (deep sleep phase) can be activated and deactivated device with push of a button • Battery power supply • Battery service live up to 5 years • Extend battery service life with HART modem interface which can be shut off • Optimized power consumption through new design, and increase in battery service life. • Simple configuration thanks to SIMATIC PDM • Device meets IP65 degree of protection • Can be used for absolute and gauge pressure measurements ■ Benefits The SITRANS P280 is a pressure transmitter that features Wireless HART as the standard communication interface. Also available is a wired interface to connect a HART modem: • Flexible pressure measurements • Save costs on writing for difficult installation conditions. Wireless technology offers cost advantages in cases where extensive wiring cost would normally apply. • It enables additional hitherto unfeasible measuring points, particularly for monitoring purposes. • Easy installation on moveable equipment • Enables cost-effective temporary measurements, for example for process optimizations. • Optimum solution in addition to wired communication and new possibilities for system solutions in process automation The aerial 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 option for direct operation on the device. The operating strategy used in this case seamlessly integrates into the strategy of all new Siemens field devices. Using the device’s control 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 service life of the battery. The SITRANS P280 transmitter features a ceramic measuring cell for gauge and absolute pressure measurements. ■ Function The SITRANS P280 can join to a WirelessHART network. It can be parameterized and operated through this network. Measured process values are transported 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, section 8 or http://www.siemens.com/wirelesshart. Detailed information on IE/WSN-PA can be found in the FI 01 catalogue, section 7 or http://www.siemens.com/wirelesshart.

Of particular interest are measuring points which are to be added and for which no MSR wiring is available. Mode of operation Where larger distances between the IW/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 products of the SCALANCE W family.
