Patent number: 7925386Abstract: The disclosure relates to a control device for a pneumatically operated actuator in the field of process automation, in particular for continuous control of material flows in the industrial environment. The control device has a communications interface for receiving an electrical setpoint value, and an output for the output of a pneumatic fluid, whose pressure is varied as a function of a control deviation. The received electrical setpoint value is suitable as a process parameter. The control device is connected via a communications channel to an actual-value encoder, which is designed to output an electrical signal corresponding to the actual value of the same process parameter.Type: GrantFiled: December 13, 2007Date of Patent: April 12, 2011Assignee: ABB AGInventors: Peter Krippner, Thomas Kleegrewe, Armin Gasch, Detlef Pape, Wolfgang Lasarzik, Wolfgang Scholz, Urs E.

Patent number: 7694571Abstract: The invention relates to a pressure sensor, the measuring cell of which is provided with at least one membrane for the protection of the pressure-sensitive element and a measuring chamber, filled with pressure medium, in which the pressure-sensitive element is housed. According to the invention, the membrane is monitored for damage, whereby at least one surface wave sensor is arranged in the chamber filled with pressure medium. On damage to the membrane occurring, process medium is mixed with the pressure medium. A substance change in the sensitive region of the surface wave sensor is thus brought about which results in a differing signal run time. Any change in run time is an indictor of damage to the pressure sensor and may be signaled as such.Type: GrantFiled: December 23, 2005Date of Patent: April 13, 2010Assignee: ABB AGInventors: Wolfgang Scholz, Armin Gasch, Raiko Milanovic, Peter Reigler

Patent number: 7284437Abstract: The invention relates to a device and a method for the status monitoring of a pressure measuring unit in an absolute or differential or relative pressure transducer, a pressure-sensitive element installed in the pressure measuring unit being impinged with at least one pressure generated by at least one membrane. During a defined diagnosis time interval, a testing element integrated in the pressure measuring unit is induced to undergo a change in volume, preferably by electrical activation. The pressure difference caused as a result in the pressure measuring unit is registered by a pressure-sensitive element. The curve registered during a diagnosis time interval is compared with a reference curve recorded with the pressure measuring unit intact. A fault indication is given if the deviations between the registered curve and the reference curve exceed predetermined tolerance values.Type: GrantFiled: April 12, 2005Date of Patent: October 23, 2007Assignee: ABB Research LtdInventors: Peter Krippner, Wolfgang Scholz, Peter Riegler, Emrullah Altiok, Jürgen Biskup, Wilhelm Daake, Raiko Milanovic, Rolf Merte, Armin Gasch, Fabrizio Lorito, Andrea Moroni, Franco Vecchiato, Corrado Bianchi, Eugenio Volonterio
