  • Publication number: 20040025598
    Abstract: A circuit board, which includes one or more sensors, is integrated in a fluid control device, such as a valve manifold and a base plate. The fluid control device selectively directs a fluid used to control pneumatic or hydraulic equipment. The sensors are used to measure physical characteristics of the fluid, such as flow rate, pressure, and temperature. A flow sensor includes a paddle and a support member. The paddle is disposed at least partially in an orifice and is displaced in response to fluid flow. The support member positions the paddle in the orifice and includes a plurality of strain gauges. The strain gauges are disposed on only one side of the support member and are mechanically stressed in response to the paddle being displaced by the fluid flow.

  • Patent number: 6304977
    Abstract: A field bus arrangement comprising at least one field bus station adapted to be connected with a serial field bus and furthermore at least one load controlled by way of a control output of the field bus station, the load being connected with a power supply line provided in addition to the lines of the field bus. The controlled switch is able to be actuated via the control output of the field bus station. The power circuits are completely decoupled, this meaning for example that the load can be switched off both by way of the field bus station itself and also by switching off the power supply line.
