20080289410 | Thermal Mass Flow Meter - The disclosure relates to a thermal mass flow meter for determining a material flow through a vessel. In this case, a heating element is mounted on a holder which is immersed into a vessel with a flowing medium. It is suggested that the holder is subdivided into two zones of differing thermal conductivity, the holder substantially having a high thermal conductivity adjoined by a short zone of low thermal conductivity in which the heating element is arranged. | 11-27-2008 |
20080289412 | Thermal mass flow meter and method for its operation - A thermal mass flow meter is disclosed for determining a material flow through a vessel. In this case, a sensor arrangement is mounted on a holder immersed into a vessel with a flowing medium. It is proposed that the sensor arrangement comprises a first and a second measuring element, with one of the respective measuring elements being heated while the other respective measuring element is not heated and that the two measuring elements can be heated alternately. | 11-27-2008 |
20090034584 | THERMOMETER HAVING AN EXCHANGEABLE MEASUREMENT INSERT, AND METHOD FOR REPLACING THE LATTER - The disclosure relates to a thermometer having an exchangeable measurement insert for measuring process temperatures of liquid or gaseous media in vessels of process installations, and to a method for replacing the measurement insert. On the basis of a thermometer in which the measurement insert is accommodated, such that it can be changed, in a protective tube which is closed at one end and has a process flange, the closed end of the protective tube being immersed, as far as the process flange, in a container in which the medium whose temperature is to be determined is situated, and the open end of the protective tube being guided at least indirectly to a connection housing in which at least connection terminals for connecting the measurement insert to a remote measured value processing system are arranged, provision is made for the transition from the open end of the protective tube to the connection housing to have a clearance fit with a cylindrical fitting surface between the measurement insert and a fitting sleeve which at least partially surrounds the latter. | 02-05-2009 |
20090100202 | WIRELESS FIELDBUS MANAGEMENT - The invention relates to a communication system for interchanging data in an automation system for communication between central and peripheral devices. A converter is connected into the communication path between the central devices and peripheral devices and being designed for line-bound communication with the central device and for wireless communication with the peripheral devices. | 04-16-2009 |
20090138104 | FIELD DEVICE - A field device of a distributed automation system is disclosed for controlling and monitoring technical processes. In order to include the field device in an installation management system, an exemplary field device has an associated wireless adapter. The wireless adapter is equipped with an identification feature which comprises the identification feature of the associated field device and a generic supplement. | 05-28-2009 |
20090187691 | Method for operation of a bus system - The disclosure relates to a method for operating a bus system, in which a plurality of subscribers communicate with one another over the same bus line and all subscribers are assigned a subscriber address from a limited address set. To avoid address conflicts, it is suggested that by each subscriber newly added to an existing bus system, the bus traffic will be monitored before the first send access to the bus with the current subscriber address, in order to form a list of already used subscriber addresses. The subscriber then assigns itself an address from the as yet unused address space according to a predefinable schema. | 07-23-2009 |
20100007208 | ELECTRONIC DEVICE AND METHOD FOR SUPPLYING OPERATING VOLTAGE TO FIELD DEVICES - An electronic device for supplying an operating voltage to field-proximal equipment, in which a bus supplies the operating voltage to the field-proximal equipment via a current loop between a field device and a voltage supply unit which are connected to the bus. The field-proximal equipment includes control means for adaptive operating-voltage matching to an instantaneous power demand. The control means utilizes the energy which is still freely available in the loop. | 01-14-2010 |
20100040112 | TEMPERATURE SENSOR FOR A PROCESS ENGINEERING INDUSTRIAL INSTALLATION - A temperature sensor is disclosed having a measuring resistor which is accommodated inside a protective tube and a proximal end of which is connected to a sensor head. The sensor head includes a measurement insert for electrically connecting the measuring resistor and a measuring transducer which is connected downstream thereof to, for example, condition measurement signals. The sensor head is formed by a cylindrical housing having an intermediate base, the measurement insert being accommodated in a lower housing section which is adjacent to the measuring resistor and is sectioned off by the intermediate base, and the measuring transducer being accommodated in an opposite, upper housing section. | 02-18-2010 |
20100091816 | TEMPERATURE SENSOR - A temperature sensor is disclosed having at least one thermal measuring element which is arranged on a carrier body to convert a temperature into an electrical measurement signal which can be tapped off by electrical connecting lines as a result of a voltage supply. A generator is likewise fitted to the carrier body adjacent to the thermal measuring element to convert thermal energy into electrical energy, and to supply the voltage to the thermal measuring element. | 04-15-2010 |
