PSC-MUX

For many applications it is necessary to have a high-precision pressure measurement tapped at different locations.

In automated systems usually a combination of a single pressure scanner and external pneumatic valves is used.

PSC-MUX pressure scanners combine both in only one device. In order to cover a large measuring range with high accuracy sensors, several overload-proof pressure scanners are connected in parallel. Depending on the applied pressure the sensor with the highest measuring accuracy in this pressure range is evaluated.

The sensors are choosen according to the needs of the customers but their ranges have to overlap.

Via software command the sensor combination can be connected to the individual pressure connectors (=multiplexing). A maximum of 5 pressure connector pairs per device is available.

All PSC-Multiplexer devices are manufactured according to the needs of our customers. Please don't hesitate to contact us!

All PSC pressure scanners ar available with Ethernet (LAN) or CAN interface.

Properties:

  • The data is transmitted as ASCII text in the unit Pascal [Pa]. Through a simple protocol, the transmission rate can be adjusted in the range between 1 and 50Hz.
  • A TARE function can be triggered either by pressing the TARE button on the front panel or via a software command.
  • For the multiplexer pressure scanner version an external power supply is necessary. 
  • Since the pressure scanner identifies itself as a virtual COM port to the system, any software can be used which supports the RS232 protocol. A sample program for use with LabVIEW is included.
