Coupling joints for torque shafts

Couplings are important accessories for torque transducers. They are used as compensation components for parasitic loads due to alignment errors. In order to enable the torque transducer to achieve very low measurement uncertainties, Kistler offers a range of couplings suitable for many installation variants. The use of such compensation components not only increases the accuracy of the transducer but also protects the components connected to it from wear.

FORCE MEASUREMENTS: PIEZOELECTRIC LOAD CELLS

In recent years, force transducers have reached a high technical standard. The transducers gain part of their high accuracy through improved calibration possibilities. The measurement accuracy of a force transducer depends to a large extent on the state of installation. Unfavourable installation conditions not only have a negative effect on measurement accuracy, but also on the dynamic properties of the measurement chain and immunity to electromagnetic fields.

More information

I piezoelectric sensors consist of two crystal disks with a foil electrode between them. When force is applied, an electrical charge is generated that can be measured by a charge amplifier. The charge is proportional to the force applied. Given their principle of operation, these sensors have a drift of 1N/minute while the measurement chain is in operation they show very small deflections when force is applied, thus offering high stiffness. This results in a high resonance frequency which, in principle, is very favourable for dynamic or quasi-static applications. Further advantages of these sensors are: a high operating temperature range high operating temperature range (-196°C; +700°C) and a easy signal summation for sensors mounted in parallel.. All transducers are made of stainless steel and are suitable for use in harsh industrial environments with stringent operational requirements. They are maintenance-free and can be installed in locations that are difficult to access. A further significant feature of piezoelectric technology is the possibility of calibrating and programming different measuring ranges due to the high accuracy. fractioning can be avoidedIt is possible to avoid fractioning, i.e. to use one sensor instead of two or more sensors with different measuring ranges, thus ensuring the most suitable full scale,simply by using the charge amplifier.

These sensors can be to be calibrated o already calibrated. Force washers can be used on both bolts and screws, so the inside diameter of force washers usually corresponds to the outside diameter of metric threads. The resulting force shunt from the bolt or screw on which the force washer is used acts as a spring element in parallel, thus reducing the sensitivity of the system. In this case, a value of approx. 10% should be expected. The force washers to be calibratedThe force washers to be calibrated cannot be calibrated at the factory and calibration is always essential. To ensure good reproducibility, it is essential that the force washer is pre-loaded. The amount of pre-stressing depends on the nominal (rated) force of the sensor and the force to be measured; when the force washer is 50% pre-stressed, it can withstand the maximum bending moments. Ideally, the pre-stress should be such that the sum of the pre-load force and the operating force is on average 50% of the washer's nominal force. This recommendation is particularly important for piezoelectric force washers. The calibrated force washers (load washers) have a high degree of protection and are supplied ready to install, offering the same advantages as strain transducers in this respect; they are therefore preferable pre-loaded and calibrated to uncalibrated washers. Furthermore, as with other piezoelectric transducers, force washers offer sufficient sensitivity to be almost independent of their nominal (rated) force.

FORCE MEASUREMENTS: STRAIN GAGE LOAD CELLS

Load cells with strain gauge technology always include a spring element to which force is applied. This force causes minimal deformation of the spring element. Strain gauges installed at suitable points are lengthened or shortened, and their resistance changes accordingly. At least four strain gauges are connected together to form a Wheatstone bridge circuit. By supplying the measuring bridge with a voltage, the resulting output voltage is proportional to the applied force. Sensors based on strain gauges show almost no drift and are therefore particularly suitable for long-term static monitoring tasks, e.g. weighing. In principle, transducers for small forces are soft spring elements and the resonance frequency of the transducers is correspondingly low. These sensors allow high-precision static calibration and the spring elements can be designed to achieve optimum reproducibility.

Strain gauge load cell 4576A, tension and compression
The strain gauge load cell 4576A tension and compression load cell, 0.5 to 200Kn, has a robust and compact design. The force does not have to be applied transversely but perfectly in the centre where the bore is located, so the measurement accuracy is highly dependent on the installation condition; unfavourable installation conditions have not only a negative effect on the measurement accuracy but also on the dynamic properties of the measuring chain and the immunity to electromagnetic fields.

Strain gauge load cell 4577A, compression only
The strain gauge load cell 4577A with compression only, from 0.1Kn to 200Kn, has a rugged, flat and compact design.

It is an economical solution that can be used in force control, joint work, measurement of static and dynamic compressive forces and on production lines. It is also resistant in corrosive industrial environments.

AMPLIFICATION: PIEZOELECTRIC AND STRAIN GAUGE SIGNALS

Signalamplification is essential for measuring mechanical quantities such as force, strain or torque. Charge amplifiers convert the output signal from a piezoelectric sensor to a proportional voltage. These voltage signals are then also used as input variables for monitoring and control processes. To meet industrial needs, Kistler offers a wide range of amplifiers with different designs, number of measuring channels, accuracy, measuring ranges, sensitivity, bandwidth, filter characteristics and scaling and signal processing options.

Piezoelectric and strain gauge force transducers

Two operating principles have become dominant in force measurement: Piezoelectric force sensors and strain gauge force transducers. Piezoelectric sensors are active measuring systems, i.e. they do not require external energy to operate. They consist of two crystal disks with a foil electrode between them. When force is applied, an electrical charge is generated that can be measured by a charge amplifier. The charge is proportional to the force applied. Due to their principle of operation, piezoelectric force sensors have an estimated drift of 1 N/minute while the measurement chain is in operation. Since this value remains unchanged irrespective of the measured force, the relative measurement error resulting from the drift is particularly unfavourable when measuring forces over long periods of time.

Piezoelectric sensors show very small deflections when force is applied because they offer high stiffness. This results in a high resonance frequency which, in principle, is very favourable for dynamic or quasi-static applications. Piezoelectric sensors can be very compact and are therefore the optimal solution when integration into existing systems is required and for rapid measurements of small forces.

Force transducers Strain gauges are passive measurement systems, i.e. they require external energy to operate. They always comprise a spring element to which force is applied. This force causes minimal deformation of the spring element. Strain gauges installed at appropriate points are lengthened or shortened, and their resistance changes accordingly. At least four strain gauges are connected together to form a Wheatstone bridge circuit. By supplying the measuring bridge with a voltage, the resulting output voltage is proportional to the applied force. These sensors show almost no drift and are therefore particularly suitable for static long-term monitoring tasks such as weighing. The so-called creep (reversible time-dependent change in the output signal that appears when a constant force is applied), is extremely small, as it can be minimised by the appropriate choice of strain gauge design.
