Field of the Invention The invention relates to a device for converting an active element, which carries out a change of states of a material, which is present in a fluid, into a fluid pressure signal or into a fluid pressure variable as a response to a parameter that characterizes a state of the material, which is present in a fluid, when the active element is actuated. The device includes an electronic circuit having a control input and a signal output, a sensor element that is acted on by the active element, and a variable which is a function of the state of the material present in the fluid, and which is connected to the sensor element, as well as an actuator that is connected to the active element and the control input and that is provided with a drive device, the control input being connected to the sensor element via the drive device. 2. Description of the Related Art A device for converting an active element, which changes the state of a material, which is contained in a fluid, into a fluid pressure signal is known from U.S. Pat. No. 4,834,422. The known device has an active element, which is adapted to generate a signal that is a function of the state of a material contained in a fluid. In this case, the device includes a circuit that has a control input and a signal output, a sensor element, which is acted on by the active element, and a variable, which is a function of the state of the material, and which is connected to the sensor element. Furthermore, the known device has an actuator, which is connected to the active element and to the control input and which is connected to the drive device. In order to be able to convert the active element into a fluid pressure signal in the known device, a control element is required. It is accordingly an object of the invention to provide a device for converting an active element that overcomes the above-mentioned disadvantages of the heretofore-known devices of this general type and that is distinguished by a simple design. In particular, it is an object of the invention to provide a device for converting an active element that does not require a control element. 4bc0debe42
