複数のトランシーバを備えた無線産業用プロセスフィールドデバイス

Abstract

The wireless industrial process field device (200) includes a process interface element (212) configured to interface with a process fluid and control or detect a process variable of the process fluid. A controller (204) is configured to control the operation of the process interface element (212). An RF circuit board (244) carries multiple RF transceivers (212), each configured to transmit and / or receive RF signals carrying information about the process variable. Multiple antennas (214) are mounted on the RF circuit board (244) to form an antenna array. Each of the multiple antennas (214) is connected to at least one of the multiple RF transceivers (212). Each of the multiple antennas (214) has a different antenna pattern. The controller (204) controls the operation of the multiple RF transceivers (212) to communicate with a remote device through an antenna array pattern formed by transmitting RF signals via the multiple antenna patterns of the multiple antennas (214).
