Part A: SciPres®
Pressure Sensor Hardware
1.0 Overview
The SciLog® SciPres® pressure sensor system consists of two major components, the SciPres®
pressure monitor, with its power supply, and the single-use SciPres® pressure sensor, with its cable.
The monitor is a small desktop package with a backlit display and seven buttons for easy interface and
menu selections. It displays up to three measured pressures and one calculated pressure in real time.
The monitor’s output signals are in both analog and digital forms. It comes with a small wall adapter
as a universal power supply.
The monitor reads and utilizes calibration data from SciPres® sensors that have been calibrated to two
points, 0 and 30 psi, or three points, 0, 54 and 6 psi depending upon the sensor purchased. It has also
been equipped with a Supervisor Password, a Max Pressure Watchdog, and a Noise Filter setting.
The “Max Pressure Watchdog” feature records in the sensor’s memory the maximum pressure seen
by the sensor while it is connected to the SciPres® Monitor. This value is displayed for a few seconds
along with the Sensor ID and calibration information when the Monitor is powered up after a sensor is
connected.
Caution: Disconnection and reconnection of the sensor while in operation may cause corruption of the sensor’s memorys and consequent loss of calibration. Please turn the
monitor off when connecting / disconnecting the sensors.
Note: The maximum recommended pressure for the sensors is 60 psi (4.14 bar). If this is
exceeded, problems with leakage and functionality can occur.
The Filter setting is used to average the pressure signals when peristaltic pump heads are used. This
makes the display readings easier to interpret, and produces cleaner graphs that are easier to read. At
the lowest setting, the data is “live”, and at the highest, it is averaged over a four second period.
The SciPres® pressure sensors utilize a silicone piezoresisitive sensing element in a polysulphone tube
available in five sizes: Luer, 3/8" or 1/2" Barb, 3/4" and 1" ‘Ladish’ Sanitary TC connections.
All sensors are pre-calibrated at the factory, and retain the calibration data on a small chip embedded
in the sensor body. The following information is retained and is accessed upon connection to the
sensor:
• ID number (Contains Size, Lot number, Mfr Code, and Calibration date)
• Calibration Factors
• Calibration Points
• Pressure Zero Offset
• Max Pressure Value

Part B: SciPres® Pressure Sensor Monitor Software
1.0 Software Overview
The SciPres® pressure monitor digitally displays inputs from up to three SciPres® pressure sensors
simultaneously, while also calculating and displaying either trans-membrane or differential pressure.
It has also been equipped with a “Supervisor Password”, a “Max Pressure Watchdog”, and a
“Filter” setting.
The “Max Pressure Watchdog” feature records in the sensor’s memory the maximum pressure seen
by the sensor while it is connected to the SciPres® monitor. The maximum recommended pressure
for the sensors is 60 psi (4.14 bar). If this is exceeded, problems with leakage and functionality can
occur. This value is displayed for a few seconds along with the Sensor ID and Cal information when
the monitor is powered up and a sensor connected.
The “Filter” setting is used to average the pressure signals when peristaltic pump heads are used.
This increases the sensor precision as well as accuracy and makes the display readings easier to
interpret when compared to ever changing values caused by pulsation. Thus it produces cleaner
graphs that are easier to read. At the lowest setting, the data is ‘live’, and at the highest, it is
averaged over a 4 second period. Please refer to the graph in section 4.0.
The “Supervisor Password” is a number between 1 and 9999 that must be entered to access the
Menu and its settings. Setting the password to 0 disables it.
The “Main Menu” allows you to change the pressure units, (psi, kPa, bar, mmHg are available) the
high and low analog range settings, adjust the baud rate and print time, change the mode between
trans-membrane, differential and none, adjust the “Filter” setting, as well as configure user-defined
hi / low pressure alarms for all four displayed values.
The SciPres® pressure monitor will also allow custom zero and single point full span calibration of
the sensors through the use of the “Sensor” button on the front panel. This is a modification of the
existing factory two or three point calibration. This can be reset or cleared if desired.

3.0 Custom Calibration Menu, Continued:
SUMMARY: This menu shows the settings used for performing a custom calibration of a given
SciPres® pressure sensor. This allows you to calibrate zero the unit for existing pressure offsets,
and re-span the unit with a NIST traceable pressure source if you wish. This procedure adds a
modification to the existing Factory Calibration, it does not modify it, and it can be reset if needed.
After connecting the sensor, press the “Sensor” button, you will be prompted for the sensor to
re-load, choose the sensor and press “Enter”. After reloading the data from the sensor, the
“Custom Cal…” screen appears. Press the “Enter” key to enter the Custom Cal menu, use the
“Exit” key to bypass it.
3.1 SENSOR PORT: Use the up/down arrows to select from P1, P2 or P3 and press “Enter”.Default = 0.0 °C (0.0 °F).
3.2 SENSOR ZERO: To zero the sensor, use the up/down arrows to change “NO” to “YES” and
press “Enter”. To bypass, leave the setting at NO and press “Enter”. Default = NO.
3.3 CAL PRESS: To Re-span the sensor at the upper limit, use the up/down arrows to select the
pressure being used for the custom calibration and press enter. To bypass, press “Exit”.
3.4 CUSTOM CAL PRESS: When you reach this screen, and are ready to perform the custom
calibration at the upper limit. Be sure you have pressurized the sensor using a NIST traceable
pressure source (gauge). Press the “Enter” key to do the calibration. You may press “Exit” to
cancel the process.
3.5 CAL IN PROGRESS: This screen is displayed during the calibration, and will count up to 10
to complete the custom calibration.
3.6 CUSTOM CAL FACTORS: This screen displays the custom calibration data, the Custom Cal Factor, (CCF) can the Custom Zero Offset (PZ).
3.7 CALIBRATION ERROR! / OUT OF RANGE: This message will be displayed if the pressure is out
of range, i.e. you’ve tried to perform a custom calibration at an elevated pressure with the
sensor un-pressurized.
3.8 SENSOR RESET: Used to reset / remove the custom calibration. Press the “Sensor” key to
reload the sensor data, and while the custom cal factors are displayed, press the “Enter” key.
The Sensor Reset screen will be displayed, and you can change the No to Yes with the
Up/Down Arrows, and press the “Enter” key to reset / remove the custom calibration.
There is an “Are you sure?” screen that will also need a Yes answer to complete this task.
This graph shows the effects of the Filter setting on the SciPres® monitor and the incoming signal
from the SciPres® sensors.
This provides the added benefit of improving the precision and accuracy of the sensor reading
by eliminating the need to interpret between ever changing high and low values caused by
pump-generated pulsation. It makes the processes easier to control and the cleaner graphs
are easier to read.
Data was collected at 1 second intervals. A peristaltic pump running at 100 mL / min was
connected to the SciPres® sensors and back pressure was applied.
The Filter setting was changed from 1 through 6 over the course of the run. Data was stable at that
point, and it was not increased further due to lack of noticeable effect at these flows and pressures.
As the Filter setting is increased, a small delay occurs in the response of the filtered data when the
pressure is changing. The maximum delay at a setting of 12 is 4 seconds. A setting of 1 yields “live”
data with no delay and no filtering.

1.0 Data Collection
SUMMARY: The SciPres® pressure monitor has two serial ports. The serial port which is labelled
“Printer / PC,” is used for RS-232 serial communication with a PC or serial printer. The second
serial port is disabled.
SciDoc software is available and includes an Excel spreadsheet with custom macros that is
automatically populated when data is received. It also automatically populates a graph in real-time
as the data is generated. Discussion of this package begins on the next page.
Alternatively, when a PC is connected to this serial port, all data generated can be sent to a
“HyperTerminal” program. HyperTerminal is OK for viewing the data in real time, but can be a
challenge for actually capturing and retrieving the data. The HyperTerminal settings are provided
for you in section 1.2 entitled “PC HyperTerminal Settings”.
1.1 SciPres® SciDoc Data Collection Software:
SciPres® offers SciDoc software to capture the data output of the SciPres® pressure monitor and
place it in an Excel spreadsheet in real-time. This spreadsheet also populates a graph to aid you in
the analysis of your process. It consists of a copy of WinWedge and a customized spreadsheet with
built in macros. It requires the use of a SciPres® RS-232 cable to connect your SciPres
pressure sensor to an available Com Port on your PC.
Minimum system requirements are Windows 98, Excel 2000 and WinWedge v3.4, which is
included in the package.
Once installed, click on the shortcut for the spreadsheet, and Excel will launch.
Press “Enable Macros” or “Enable Content”to begin the process for data collection. One may
choose to have the computer recognize this as a trusted document, if desired.
Note: If you are opening a previously saved data set, choose “Disable Macros” or “Disable
Content” instead.

The following screen will be displayed:
Choose the Com Port you have the SciPres® pressure monitor connected to. Click on the “OK”
button and WinWedge will start, showing itself as an icon in your system tray.
You are then presented with the next screen:
WinWedge Icon
Enter all of the approprite Operator information in this dialog box and click on “OK”.
Note: The “Clear Data” button on the spreadsheet does not affect the information in these
fields. You may click on the “Operator Info” button and update these fields as needed.
Clicking on “OK” leaves the next screen, ready to get started collecting data from the SciPres®
pressure sensors.

When ready, turn on the SciPres® pressure monitor, pressing the “On / Stby” button. The monitor
will load the calibration data from the sensors, and place that information in the spreadsheet. All
remaining data generated will automatically be placed in the cells of the spreadsheet, and the
charts populated with the same data. The text box in the upper left of the spreadsheet contains the
header information that is generated by the SciPres® pressure sensors and monitor. This will list
the version, the calibration data, all operating parameters, alarm settings and alarm limits.
Note: If you have clicked on “Cancel” on either of the two previous screens, you may click on
the “Com Port Setup” or “Operator Info” buttons to complete these tasks.
A chart of Pressure versus Time has been included for your use, and you may view it by clicking on
the appropriate tab at the bottom of the worksheet.
You may, of course, create your own charts or modify those included by adding trend lines,
changing titles, etc.

When you are finished with a run, the screen will look similar to this one:
Click on “File”, “Save As” and choose an appropriate file name based on your needs and store it in
a different folder. When ready for another run, simple press the “Clear Data” button, or close and
re-open the original file.
