摘要： The invention relates to a strain gauge, comprising at least one optical waveguide (5) fastened to a thin support (1). The optical waveguide (5) has at least one section (10) with a fiber Bragg grating (6), which serves the detection of strain. The invention is characterized in that the optical waveguide (5) outside of the fiber Bragg grating section (10) is covered on both sides of said section by two fastening elements (3, 4). In this way, the optical waveguide (5) outside of the fiber Bragg grating section (10) is fastened to the support (1) with force fit. Between the two lateral fastening elements (3, 4), a relatively soft elastic fixing element (2) is fastened around the optical waveguide (2), the element fixing at least the fiber Bragg grating section (10) with positive fit to the support (1).

摘要： An optical strain gage incorporates an optical waveguide or fiber that includes a sensing section with a fiber Bragg grating, which serves for detecting a strain in a strainable member on which the strain gage is mounted. At locations displaced away from the fiber Bragg grating section, on both sides thereof, the optical waveguide is covered by two fastening elements, which secure the optical waveguide in a force-transmitting manner on the strainable member or a bottom support. Between the two fastening elements, a relatively soft elastic fixing material surrounds the optical waveguide and fixes the fiber Bragg grating section on the strainable member or bottom support in a form-fitting and force-isolating manner.

摘要： An electrical bridge circuit arrangement for multi-position measuring includes an auxiliary or standard resistance half bridge and measuring resistances (M.sub.1, M.sub.2, M.sub.3) arranged in respective bridge arm circuits. An auxiliary or standard resistance (E) common to all measuring resistances is part of the bridge circuit. The measuring resistances (M.sub.1, M.sub.2, M.sub.3) and the auxiliary resistance (E) can be connected to a supply voltage by means of supply voltage switches (S.sub.12, S.sub.22, S.sub.32 ; S.sub.E3). The voltages present at the ends of the supply voltage diagonal of the bridge circuit are tapped by conductors (L'.sub.12, L'.sub.22, L'.sub.32 ; L'.sub.E3) and are supplied to the inputs of operational amplifiers (1, 2) which adjust or control the voltage level at the tapping point to a reference level. Voltage drops across the measuring diagonal are tapped by additional conductors (L.sub.31, L.sub.21, L.sub.11 ; L.sub.E1) and half of each voltage drop is superimposed on the supply voltage of the measuring arm while the other half is superimposed on the compensating or standard arm of the bridge with respect to the tapping of the compensating half bridge. Therefore, any voltage drops across the measuring diagonal cannot affect the measurement results in spite of long cables to the measuring resistances and in spite of the auxiliary or standard resistance (E) arranged in the measuring bridge circuit arrangement.

摘要： The invention relates to an arrangement for the torque measurement of rotating machine parts with a strain measuring bridge (2) arranged on the rotor, which bridge consists of circuit-connected strain gages. The output signals of the strain measuring bridge (2) are amplified with an amplifier circuit (3) and are converted into frequency-proportional signals in a subsequent or downstream voltage-frequency converter (4). The invention is characterized in that the voltage-frequency converter is embodied as a so-called synchronous voltage-frequency converter (4), which is fed with a quartz-controlled frequency. For the suppression of the so-called frequency jitter, a follow-up synchronization circuit (PLL) (6) is provided after the synchronous voltage-frequency converter (4), which circuit suppresses the alternating frequency of the synchronous voltage-frequency converter (4), so that a frequency signal that is proportional to the analog strain measurement signal is produced at the output. These frequency-modulated measurement signals on the rotor side (14 are inductively transmitted via a transmitter circuit (9) onto a stator, on which an evaluating circuit is provided, which again produces analog signals or corresponding digital signals from the frequency-modulated measurement signals.

摘要： A measured voltage is converted into a digital value according to the follow-up principle. A compensation signal is added to the measuring signal so that the mean value of both signals becomes zero. The compensation signal is formed from at least two auxiliary compensation values which are each a square wave signal having a fixed frequency and a keying ratio which is adjustable independently of the other square wave voltage. The keying ratios are varied or adjusted so that the compensation signal compensates the measured signal. In order to achieve this the value deviating from zero of the sum of the measured signal and the compensation signal is integrated, converted into digital values, and supplied to a PI-or PID-control circuit which controls in a closed loop manner the keying ratios of the square wave signals. The I-value of the PI- or PID-control circuit serves as a measure of the measured voltage.
