Application
The device is a non-contact electronic ultrasonic filling level transmitter for continuous measuring of
filling levels in liquids, pastes and coarse bulk materials.
The use of a non-contact operating measuring systems opens a broad range of application possibilities
like e.g. at aggressive process materials.
Function
The transducer of the ultrasonic sensor transmits ultrasonic pulses to the product surface.
These pulses are reflected by product surface and received back by the transducer as echoes.
The running time of the ultrasonic pulses from emission to reception is proportional to the distance
and hence the level.
The determined level is converted into an appropriate output signal and outputted as measured value.
An integrated temperature sensor compensates changes in the velocity of sound caused by
temperature changes.
The interference echo suppression function ensures that interference echoes (e.g. from edges,
welded joints and installations) are not interpreted as a level signal.
The measuring value is diagrammed at the display, whereby it can be selected between different
display styles (digital value / manometer / chart / bar graph).
In the internal ring memory up to 1 million measuring values can be recorded durable.
The measuring value can be converted into a continuous current signal 0/4...20 mA resp. voltage
signal 0...10 V or monitored by four PNP switch outputs for exceedance of limit values.
By the use of the Bluetooth interface records measuring values can be downloaded. Moreover the
configuration data can be downloaded or uploaded. This allows a fast and simple configuration of
multiple devices with the same preferences.
Additional functions can be realized on request:
•
Real-time-clock for storing of the measuring values with time signature (data logger)
• Communication interface RS485 (different protocols, e.g. Modbus)
• Communication interface USB (Slave)
•
Communication interface UART
