The PSC-series pressure scanners are designed for simultaneous measurements of multiple
pressure signals.
The PSC8-USB offers the ability to connect up to eight differential pressure probes, where
each pressure port has its own reference port.
The PSC16/24-USB features 16/24 pressure channels with a common reference port. A special
differential version with reference ports for each line is also available.
Different measuring ranges are available, noting that all channels are equipped with the same
kind of sensor.
Acquired data is internally scaled to the unit Pascal [Pa] and transmitted as plain ASCII text.
The acquisition rate can be adjusted within the range of 1 to 50 [Hz], using an intuitive
communication protocol.
The tare function is activated either by pushing the TARE-button on the front panel or via a
software command.
Optionally, the 8 channel device is available with built-in magnetic valves, allowing automatic
zero compensation measurements while pressures remain connected.
PSC-USB and -CAN devices are powered via USB respectively CAN port. To operate the
magnetic valves and PSC-LAN devices an external power supply has to be connected to the
back panel.
PSC-USB and -CAN devices are both equipped with a USB interface, allowing it to be easily
configured. In this case the scanners identify themselves as a virtual COM-port to the host PC.
Thus, any software which supports the standard RS-232 protocol can be used for
communication. The LAN-version sends the data using the TCP-IP protocol. A direct connection
can be set up via Telnet (Port 10001). The application putty.exe can be used when working with
Windows. With LabVIEW (National Instruments), the use of the VISA-class is recommended
due to the possibility to access both USB- and LAN-devices. An exemplary software for the use
with National Instruments LabVIEW is provided.
