Process variable transmitter with loop-powered wireless transceiver

A process variable transmitter includes transmitter circuitry for determining a process variable from a sensor signal produced using a process sensor. The transmitter circuitry has at least one operating parameter. The process variable transmitter also includes a wireless communication module configured to be powered by a two-wire process control loop. The wireless communication module is capable of communicating wirelessly with a general-purpose mobile device using a general-purpose wireless communication standard such that the wireless communication module can instruct the transmitter circuitry to change a value of the at least one operating parameter based on a wireless message received from the general-purpose mobile device. 种过程变量变送器，包括用于根据使用过程传感器产生的传感器信号来确定过程变量的变送器电路。变送器电路具有至少个操作参数。变量变送器还包括被配置为由双线过程控制环路供电的无线通信模块。无线通信模块，能够使用通用无线通信标准与通用移动设备无线地进行通信，以使得所述无线通信模块能够基于从所述通用移动设备接收的无线消息来指示所述变送器电路改变所述至少个操作参数的值。
