<p>A process variable transmitter (10) providing a transmitter output representing a process variable (14) sensed by a sensor (18). The transmitter (10) has a filter with a bandwidth which is automatically adjusted based on noise detected in a sensor output. When the transmitter (10) senses higher sensor noise levels, it automatically decreases the bandwidth to damp noise in the transmitter output. When the transmitter (10) senses lower sensor noise levels, it automatically increases the bandwidth to provide faster response to changes in the process variable.</p> |
