- Each of the two pressure sensors 66, 67 provides an electrical sensor signal to the control device 63 via the assigned sensor lines 86, 87, from which the control device 63 can determine a pressure difference between the first pressure sensor 66 and the second pressure sensor 67 and based on the known flow resistance of the throttle 65 can determine a flow through the third fluid channel 35.
- a third pressure sensor 68 and a flow measuring device 69 are arranged in the fourth fluid channel, which are connected to the control device 63 via sensor lines 88, 89 and which are also designed to provide sensor signals to the control device 63.
- the use of the combination of the third pressure sensor 68 with the flow measuring device 69 enables an immediate flow measurement in the fourth fluid channel 36.
- the pressure sensors 66 to 68 are each arranged at the end of a branch line 93 to 96 on an assembly surface 100 of a sensor board 97, in which the sensor lines 86 to 89, which are drawn separately for illustration purposes only, are in practice are integrated.
- it can be provided to close the respective branch line 93 to 96 in a fluid-tight manner with an assigned pressure sensor 66 to 68, as shown in FIG. 4, or alternatively to insert a blind plug into the respective branch line 93 to 96, provided there is no pressure measurement or another measurement (temperature measurement, humidity measurement, etc.) for the third fluid channel 35 or the fourth fluid channel 36 is provided.
- the assembly area is 100 of the sensor board 97 is arranged opposite an underside 50 of the carrier plate 2.
- control device 63 is assigned a sensor line 90, which is provided at the end with a plug connector 91.
- a sensor cable 98 is plugged into the plug connector 91 and is used for an electrical connection between a position sensor 99 assigned to the compressed air consumer 82 and the control device 63.
- the connecting channels 43 to 46 formed in the respective channel plates 24 to 27 have the designations P for the pressure supply that were previously common in pneumatics , S for the ventilation, A for the first working connection and B for the second working connection.
- P for the pressure supply that were previously common in pneumatics
- S for the ventilation
- A for the first working connection
- B for the second working connection.
- the assignment of the respective function to the respective connecting channel 43 to 46 is therefore identical to the schematic representation according to FIG Arrangement of silencer 78 and compressed air source 79 is made.
- valve module system can hereby be used, for example, to deliver gas mixtures with variably adjustable proportions of compressed air and a pressurized gas.
- the channel plates 24 to 27 are each provided purely as an example for coupling two valve assemblies 18. Depending on the application, all can be done in the same way as with the figure
- a redundant coupling of four valve assemblies 18 can also be provided, in which case the connection configuration shown in each case is doubled, in particular mirrored, in the respective channel plate 24 to 27.
- a supply connection 31 is connected to the first connection channel 43
- a second supply connection 31 is connected to the second connection channel 44
- the two first valve connections 20 are connected to the third connection channel 45
- the two second valve connections 21 are to the fourth connection channel 46 tied together . Accordingly, one valve assembly 18 is used as a ventilation valve for the two connecting channels 45 and 46, while the other valve assembly 18 is used as a ventilation valve for the two connecting channels 45 and 46.
- a supply connection 31 is connected to the first connection channel 43 and a second supply connection 31 is connected to the second connection channel 44. Furthermore, all valve connections 20, 21 are connected to the third connection channel 45, while the fourth connection channel 46 has no connection.
- ventilation and venting of a compressed air consumer can each be realized with double volume flow, whereby these compressed air consumers can be, for example, a single-acting pneumatic cylinder.
- both supply connections 31 are connected to the first connection channel 43, while the respective first valve connections 20 are connected to the third connection channel 45 and the respective second valve connections 21 are connected to the fourth connection channel 46.
- a fluid flow control for two separate compressed air consumers which are fluidly connected to the third connecting channel 45 or are connected to the fourth connection channel 46.
- both supply connections 31 are connected to the first connection channel 43 while all valve connections 20, 21 are connected to the third connection channel 45 and have no connection to the fourth connection channel 46.
- a fluid flow control for a compressed air consumer can be carried out with a flow cross section that is twice as large as that of the channel plate 27 according to FIG.
- each of the stub lines 93 to 96 can be assigned different sensors as required, each being assembly variants for the sensor board 97, while otherwise no changes, in particular to the carrier plate 2, are required.
