FUTEK Advanced Sensor Technologies Multi Axis Load Cell are designed to measure a multiple of forces and moments simultaneously with a single Load Cell.
Multi Axis Suppliers of load cells can accurately measure up to six components (3 forces and 3 moments) of load. For example, Independent strain gauge bridges are used to measure three directions of force: Longitude, Latitude, and Vertical, as well as, the moments about each force direction. Separate receptacles or cables are provided for each axis of measurement. A careful structural analysis has been done to isolate the forces and moments, which results in a reduction of cross-talk sensitivities.
All designs are one piece flexures, machined and gauged to give optimum output, stiffness and durability. For example, one of our more innovative designs, the Stick Shift/Gear Shift Knob Transducer offers a lightweight, robust feature comprised of Anodized Aluminum and weighing as little as 9 oz. Its special ergonomically designed cover contains anti-slip notches for proper handling coupled with less hand strain on the user. |

The technology for our 'TorqSense' RWT310/320 Series Torque detection is based on the patented technology of measuring the resonant frequency change of 'Surface Acoustic Wave' (SAW) devices in a non-contact manner when strain is applied to a shaft to which the Industrial saws are fixed. The applied torque causes a deformation of the quartz substrate of the SAW device, which in turn causes a change in its resonant frequency. Essentially the SAWs act as 'frequency dependent' stress gauges.
The frequency signal measuring the resonant frequency is coupled via a non-contact RF rotating couple from the shaft to a fixed pick-up and it is the analysis of the difference in resonant frequencies between the two SAW devices, with electronic processing and calibration, that gives a precise indication of the torque transmitted by the shaft. SAW devices have a high immunity to magnetic fields allowing their use in motors, for example, where other analog technologies are susceptible to electronic interference and are not suitable.
The use of this patented measurement technique results in a transducer being able to sense torque bi-directional, with fast mechanical and electrical responses. As the method is non-contact it has also complete freedom from professional brushes or complex electronics, which are often found in traditional torque measurement systems.

Benefit from the many new advantages of measuring with light - without having to abandon the ruggedness and convenience of the classical strain gage.
HBM's optical strain gages are made from fibers of glass with a very small core diameter of no more than 4 to 9 manufacturer of micrometers. In comparison, the diameter of human hair ranges from 60 to 80 micrometers. The fiber core is surrounded by a cladding layer from purest glass with a diameter of 125 micrometers.
HBM patented optical strain gages utilize proven technology, and are easy to work with. There is no difference in the handling of optical or traditional (electrical) types of strain gages. You don't have to learn new skills: Bonding, covering, connecting, etc. are all identical. The patented design protects the fiber and makes configuring your test setup quick and convenient. Benefit from both optical sensor technology and the wide range of accessories for electrical strain gages.
Best of both worlds: HBM's measurement technology enables the simultaneous acquisition of data using both electrical and optical strain gages. The EasyOptics module in HBM's catman®AP software enables you to jointly acquire and analyze data from different types of sensors.

The E100 SBT Series Stress gauge Base Mounted Transducer has a substantial easily mounted body, which houses the shaft and strain gauge assembly. The shaft is mounted on its outer end in a ball race, ensuring accurate torque measurement. A professional chuck accommodates simple adapters which can be supplied with standard square dimensions, or machined to suit specific applications.
|
|
| It is often the case that torque in a rotating shaft can be measured with a stationary, reaction torque sensor at some point in the powertrain. This is due to the existence of an equal and opposite force (torque) necessary to hold the drive and driven equipment in place. |
|
| The RDP range includes digital telemetry, slip ring, rotary transformer, compact and square drive slip ring styles. |
|
| Rotary torque has historically been difficult and expensive to measure. However, by using existing technology in a novel way, inexpensive transducers can be produced for situations where monitoring or control of drive mechanisms is required. Developed in conjunction with a UK government programme,TORQSENSE. E300 RWT (Rayleigh Wave Transducers) are the world's first low cost non-contact rotary torque transducers suitable for OEM applications. |

The shockproof digital load cell is based on a capacitive measurement principle where a non-contacting ceramic sensor is mounted inside the load cell body. As the load cell contains no moving parts and the sensor is not in contact with the load cell body, the load cell tolerates shocks, torsion, and very high overloads and sideloads. Therefore, the mechanical installation of the load cell can be done without expensive and complicated mounting kits and overload protection devices.
The electrical installation of the digital load cell is pure plug-and-play as the signal from the non-contacting sensor is directly converted, compensated and calibrated by a microprocessor to a digital load cell output in grams, kilograms, or Newton. Measurements and status codes are transmitted as RS485 data on a single professional wire coaxial wire (RG-58) which may be up to 100 meters long.
The technology and mechanical design of the Eilersen suppliers of load cells is covered worldwide by a number of patents. |

The increased use of fiber composites and the systematic optimization of components presuppose a precise knowledge of the load situation. In many applications, sensor integration is the only way to meet the demand for modern lightweight structures with regard to production control, load monitoring, damage analysis and control signal generation.
HBM’s new LI66 strain gages are directly embedded in the structure during the fiber composite production process. This allows measurements at spots that are no longer accessible after production.
The most obvious feature of the LI66 strain gage is the two vertically attached contact pins, for contacting the strain gage embedded in the material. The measuring leads are only connected to the gold-plated pins after manufacture, outside the structure, which makes all the handling easier.
The LI66 strain gage is of a symmetrical design, with structural strain being applied equally to the measuring grid from both sides. Depending on the requirement, the user can decide whether the pins should be contacted inside the structure or on the outside. Thus, for example, with sandwich structures, the measuring leads or customized electronics can be introduced into the foam core. |
