DNB level monitoring system
Transmitter assembly is housed in an explosion proof water-resistant enclosure. The Transmitter is coupled to a mechanical gaugehead, consisting of a rotating shaft and drum wound with cable and terminated at a float. The Transmitter measures the float movement with a rotary optical encoder and converts it to a 4-20 mA output signal. Span/zero and liquid levels can be set via the Calibrator. These values are retained in memory indefinitely.
