MODEL DCU-11 : Self-Contained Ultrasonic Level Sensor
General Description:
The Model DCU-11 Ultrasonic Level Sensor is a highly accurate distance sensor used
to measure water level. Units with maximum measurement ranges of 35 ft. and 50 ft.
are available. The self-contained feature eliminates the necessity for an external
controller. The 4-20 mA and trip point outputs of the Model DCU-11 are programmable
to anywhere within the sensing range.
The unit is contained in rugged PVC housing which is environmentally sealed and enables
the sensor to provide reliable performance in harsh environments for extended periods of time.
A keypad is mounted on the back of the sensor and is opened for initial setup. The
keypad is then sealed with an O-ring fitted cap to preserve the NEMA-4 rating while
the sensor is in operation.
The Model DCU-11 is microprocessor controlled to enable total programmability and
signal filtering capabilities. The AutoSense software provides automatic filtering
of unwanted echoes received back from the perimeters of the ultrasonic beam pattern.
This software also provides automatic adjustment of the sensitivity of the sensor.
Temperature compensation is achieved by use of an internal thermistor which preserves
the sensor accuracy over a wide range of temperatures. |
