Pressure Sensors
Accommodates one SciPres
®
pressure sensor using the P1 Port.
P2 and P3 Ports may be used as alternates. Pressure is used for monitoring
and alarms. The user selects P1, P2 or P3 as the pressure source.
Pressure Displayed
With a resolution of 0.1 psi (0.007 bar); choice of psi, bar, kpa.
Pressure Range: 0-60 psi
(0 - 4.14 bar)
The default pressure range of the sensors is 0-60 psi (0 - 4.14 bar), and is
calibrated at the factory. Most peristaltic pumps generate pressures up to
40 psi (0 - 2.76 bar). This can be re-calibrated using an external pressure
reference source.
