AquaSense graphic user interface

AquaSense uses a Windows Graphic User Interface (GUI) for setup and calibration.  Here's how it works:
Single moisture sensors can use either RS232 or RS485.  For multiple sensor systems, connect sensors in daisy-chain or bus fashion, using RS485.  USB/RS485 adaptor plugs into computer.  The RS485 protocol is Modbus compatible, allowing the sensors to be used in SCADA systems. Load the software onto a laptop or PC from CD or internet and run through the guided setup of your serial port. Same software is used for both AquaSense aggregate moisture sensors and MixTron mixer moisture sensors.  They can even be connected on the same RS485 line if the batching controller can handle it.

Click the Discover Sensors button and the software automatically makes the connection, runs through all sensors on the line and reports back as seen at left. Each sensor is identified, showing you which ones are on-line, together with the current moisture readings in filtered and raw states and the temperature at the sensor faceplate.

Configuration screen allows entry of setup parameters with easily understood titles. For more complex parameters, complete manual is available at the click of a button, embedded within the software. Multiple languages are available directly on the menu - contact us for availability of your choice.

Calibration screen displays current moisture value and raw value, plus temperature reading. Table allows entry of oven-dry test results, along with corresponding sensor readings. You can select or disable each set of readings according to the graph at right or a "consistency" value that shows the best fit of your readings, allowing you to obtain the best calibration curve. Up to 10 such tables can be entered for different materials such as sand and different sizes of aggregates, allowing the same bin and sensor to be used for these different materials with full accuracy. Included in the moisture pobe calibration software is a full instruction manual and a guide on doing oven-dry moisture tests.
