SITRANS P280 WirelessHART transmitter

■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

■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.

■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.
