APPENDIX C: PressureMAT Data Acquisition Software
The PendoTECH PressureMAT (PMAT) monitor/transmitter that is used to read the PendoTECH Pressure
Sensors comes with an RS232 data port as a standard feature. PendoTECH has a customized software package
(Part # PMAT-GUI ) to trend data real-time and also collect the data to a file that can be opened by programs
such as Excel. The software has settings to choose the PressureMAT model from a list and it can optionally
perform calculated values such as DeltaP and also trans-membrane pressure that are used for certain filtration
applications. PMAT-PLUS models will collect the flow data into a trend separate from the pressure data. The
PMAT-2PLUS model has an analog input port to which different sensors such as the PendoTECH Temperature
Sensor, UV Sensor, Turbidity Sensor or other sensor can be connected via their 4-20mA transmitter and this
data can be logged with the pressure and flow data. Additionally, a scale with an RS232 output maybe plugged
into the PC directly and the software can acquire weight data along with the PressureMAT data.
Setup View
The setup view is used to enter information specific to the PMAT model and to select calculated values for specific
applications. Data collection from a scale can be activated here also. The units of measure are selected to match the units
on the PressureMAT and scale. At the top, information can be entered that is specific to an experiment and this data is
written to the header of the data file when the data file is created. The data file location is also displayed. The data file
may be updated at a rate of every 2 seconds or slower. All of the inputs to this view are locked out when the “Start Process
Data Collection” button is clicked.
The PMAT model and units are
selected by pick-lists. These units are then used for the trends view and used in the column headers
of the data files to indicate the units
of the values in each column.
