摘要： A two-wire temperature transmitter (12) is coupleable to a two-wire process control loop for measuring temperature of a process. The transmitter includes an analog to digital converter (20) configured to provide digital output (22) in response to an analog input (24). A two-wire loop communicator (26) is configured to couple to the process control loop (16) and send information on the loop (16). A microprocessor (28) is coupled to the digital output (22) and configured to send temperature related information on the process control loop (16) with the two-wire loop communicator (26). A power supply (30) is configured to completely power the two-wire temperature transmitter (12) with power from the two-wire process control loop. A temperature sensor (34) comprises at least two (16) temperature sensitive elements having element outputs which degrade in accordance (60, 62, 64, 66, 68) with different degradation characteristics. The element outputs are provided to the analog to digital converter (20), such that the microprocessor (28) calculates temperature related information as a function of at least one element output from a first temperature sensitive element (60, 62, 64, 66, 68) and at least as a function of one degradation characteristic of a second temperature sensitive element (60, 62, 64, 66, 68).

摘要： The pressure of a motor vehicle wheel can be determined by means of a device (1), independent of the wheel mechanically fixed to an element (2) of the body (3, 14) of the vehicle oscillating with the wheel (4). In order to determine tyre pressure, preferably absolute pressure, by combining the evaluation of data concerning the rotational speed and analysis of axle frequency, said device (1) comprises a signal preprocessing unit (6) provided with electronic components for processing sensor signals, said unit being connected to a magnetic sensor element (7) and an acceleration sensor element (8) or to a combined magnetic/acceleration sensor element (5) by an electrically conductive connection (9). The magnetic sensor element (7) or the combined magnetic/acceleration sensor element (5) is operatively connected to a magnetic encoder (16) arranged on the wheel side. In order to improve determination of characteristic quantities, the oscillating behaviour of at least two wheels (4) are analysed.

摘要： The invention relates to a transducer (4) and a method for determining measuring values and for exchanging data between an evaluation device and the transducer (4), which are connected by means of at least two connecting lines (2', 2; 11, 12). Data which is pre-determined by means of the evaluation device is read out of the data memory and/or rewritten into the same via at least two connecting lines (2, 2'; 11, 12) which have the same electrical potential in the measuring operation. The data memory is embodied as a data memory module (5) and contains a current limitation circuit (2) by which means the system can be switched from the measuring mode to a communication mode for data transfer. The lines (2, 2'; 11, 12) are thus provided for switching into the communication mode and for exchanging data during the measuring operation, and for feeding the transducer (4) and/or for detecting measuring values.

摘要： A current regulator is provided for a two wire sensor and comprises first and second conductors arranged to provide a sensor output current, a first resistance and a current reference coupled across the first and second conductors, and a second resistance and sensor load terminals coupled across the first and second conductors. An amplifier has first and second inputs and an output. The first output is coupled to a first junction between the first resistance and the current reference, the second input is coupled to a second junction between the second resistance and the sensor load terminals, and the output is connected to the second input. The amplifier controls a first junction to be substantially equal to a second voltage at the second junction.

摘要： The invention relates to a measuring device, for measuring an industrial process variable, with a pre-set maximum power consumption for the measuring device. The invention particularly relates to a measuring device for connection to a current loop, in particular, a 4 - 20 mA current loop, or to a digital communication, with devices for controlling the measuring operation of the measuring device in conforming with the predetermined power consumption. The regulating devices thus control the power consumption of the measuring device during measuring operations, such that the power consumption used may approach the predetermined power consumption value without exceeding said value.

摘要： The inventive two conductor measuring device (MS) is intended for use in a means of transport, especially in a ship, and is supplied on-board with a current of a current loop, which originates from a source circuit (Q). Said source circuit is certified in accordance with a valid standard IEC-1000-4-5, especially in accordance with standard IEC-1000-4-5:1995, is supplied with power by a primary vehicle electrical system (NP) of the means of transport, and serves to supply a secondary vehicle electrical system (NS) with power. The two conductor measuring device (MS) is designed in such a way that it can not be certified for an electromagnetic compatibility in accordance with valid standard IEC-1000-4-5. During a method for testing the two conductor measuring device (MS) for electromagnetic compatibility, a hybrid generator, especially in accordance with standard IEC-60-1 or IEC 469-1, is used for generating a current/voltage surge. A decoupling network for simulating the source circuit (Q) is connected in outgoing circuit to the hybrid generator. A two conductor measuring device (MS), which does not satisfy the test specifications of the standard IEC-1000-4-5:1995, is connected in outgoing circuit to said decoupling network, and a type of approval for use on the secondary vehicle electrical system (NS) is granted to other two conductor measuring devices of the same type when the tested two conductor measuring device has withstood the test.

摘要： The invention relates to a measuring transducer in which a sensor signal (2) is digitized and is subsequently conditioned in an arithmetic unit (7) to create a specified value (A) which is then converted into an analog output signal (I). According to the invention, the output signal (I) is acquired by the measuring transducer, is digitized and is then transmitted to the arithmetic unit (7) which determines a variation between the output signal (I) and the specified value (A). In doing this, the error of measurement of the measuring transducer can be determined, indicated and optionally corrected in the arithmetic unit (7) when converting the digital specified value (A) into the analog output signal (I).
