5.7 Setup: Pressure Sensor
Pressure Sensor
is used to configure settings related to the SciPres Disposable Pressure
Sensors. The following can be configured; Range, Units, Source (control and alarms), Filter
(signal noise) and Zero/Span.
Range:
Set the overall pressure range, the Default is 60.0 psi, and is the maximum.
Changing this setting requires re-calibration of the sensor signals.
Units:
Select between Psi, Bar, and KPA. Default = Psi.
Source:
Controls the source pressure sensor for control in Constant Pressure Mode, and
for all pressure alarms. Select between P1, P2 or P3. Default = P1
Zero:
Used to “Zero” the sensors to establish the zero offset cause by the circuitry and any
inherent hydraulic pressure in your tubing beyond the pump head. Connect the sensor, and
remove any pressure from the system. Select the sensor, P1, P2 or P3 and press “Zero”.
You are prompted to confirm the action. “Span” should not be used on a routine basis, as it
sets the max input value. NOTE: Do not Zero P1, P2 or P3 unless a sensor is connected.
The display should read “--.-“ with no sensor connected. If it reads 0.0 in this state, connect
the sensor and re-zero it.
Filter:
This feature filters out the pulsations in the pressure signal due to the peristaltic
nature of the pump head. This provides better control and easier to read values, as
well as improved graphed data. Select from 1 to 7, 1 = no signal filter, 7 = maximum filter.
Default = 4.
