Abstract
A wireless circular chart recorder is presented. The wireless chart recorder includes a probe for sensing a process variable, a wireless transmitter coupled to the probe, a circular chart recorder having an input terminal, and a wireless receiver coupled to the input terminal of the circular chart recorder. The wireless transmitter receives data including the sensed process variable form the probe and transmits signals including the data over a wireless communication path. The wireless receiver receives the transmitted signals over the wireless communication path and provides the received signals to the circular chart recorder for display thereon. In one embodiment the process variable includes at least one of temperature, voltage, relative humidity, pressure, strain, resistance, motion, light, current, velocity and flow.
