Torque Measurement Systems

Product Details:

The tJRS Opta is the only fully automated joint test bench that is based on a threaded fastener. This means that joint conditions can be set up in the same way as in real fastener applications, and also the joint can be automatically “backed off”. As a result, tools can be tested offline under the most realistic conditions of any automated joint simulator, in a quick and efficient manner.

Traditionally, automated joint test bench’s have used friction brake systems in place of a threaded fastener. The reasons for this were to overcome the two main issues which are having to reverse, or back-off, after each rundown and the cumbersome nature of re-configuring the joint characteristic.

Whilst friction brakes can easily be reset, removing the back-off issue, they introduce many of their own problems often resulting in the simulator having significantly different properties to actual joints the tools will be used on.

Key Features:

• Torque or force indicator and data collector
• A threaded fastener and nut
• Fully automated quick release of fastener and variable joint rate from soft to hard
• Tool testing in accordance with VDI/VDE2647
• Comprehensive management software (OMS)
• Torque, angle and impulse count
• Track, peak, 1st peak (click) and pulse measurement

Torque Star Opta is the equipment of choice for the measurement and collection of torque data in the manufacturing environment. TorqueStar Opta's range of software features can be individually specified to give a configuration most suited to the requirement, from a simple no-frills readout to a comprehensive audit tool with display of torque curves and specialist measurement routines.
The basic TorqueStar Opta performs bi-directional measurement of torque, angle and pulse count in track, peak, 1st peak (click) and pulse measurement modes. For additional information, cycle time duration and tool speed can also be displayed. Time and date stamped readings can be set to print automatically.

The easy to read display gives a simultaneous view of all relevant information during the measurement process, while the simple alphanumeric keypad enables fast data entry when required.Light enough for carrying on a neckstrap, yet robust to withstand the rigours of the factory environment, TorqueStar Opta also sports integrated rubber bumpers to protect finished product from accidental damage.Upgradeable via enablement of software modules to add traces (torque vs time or 2nd parameter; 2nd parameter vs time), data storage, audit scheduling, and other options. TorqueStar Opta can be used in conjunction with Crane’s entry level torque audit software package Opta Comms Opta Comms Plus.

Key Features:

• Static accuracy ± 1% FSD of connected transducer.
• Measures bi-directional torque; angle; pulse count; RPM; cycle time duration.
• Modes: Track, Peak, Pulse, Force.
• "Plug Play" with Crane UTA transducer system and wrenches.
• Manage and share data with your computer system (RS-232).
• Audible and visual indication of torque status (HI/OK/LO).
• Backlit grafic LCD, simple screen navigation, choice of operating languages.
• Battery powered with charger.

Product Details:

The CheckStar Multi is the latest generation of Crane Electronics market leading CheckStar in-line rotary torque transducers. It raises the standard for dynamic torque and angle measurement of all continuous drive and impulse tools, with proven reliable performance in thousands of applications worldwide.

The CheckStar Multi fits in line between the assembly tool and the fastener, measuring the actual torque applied and angular rotation of the fastener, under production conditions.

The low inertia design of the CheckStar Multi ensures accurate and repeatable measurement of high speed transients, such as the point of shut-off on continuous drive tools and the pulsing of impulse tools.

Using on board intelligence the CheckStar Multi is automatically recognised by a Crane data collector or readout device, eliminating set-up errors and enabling logging of serial number against measurements for complete traceability.

Key Features:

• In line rotary torque transducer with optional angle measurement
• Patented design ensures no brush bounce even when used with impulse tools
• Suitable for use with all continuous drive tools, impulse tools and torque wrenches
• Compatible with most industry standard data collectors and readouts
• Automatic transducer recognition with Crane data collectors and torque readout devices
• Easily viewed light ring showing status, when used with Crane data collectors and readout devices

Crane’s Check Star Rotary Torque Transducer sets the standard for dynamic torque and angle measurement of all continuous drive and impulse tools, with proven reliable performance in thousands of applications worldwide.Whatever the vibration and shock loads experienced, CheckStar’s patented contact system ensures a connection is always maintained between the readout and the strain gauges. Inferior systems suffer from ‘brush bounce’ that leads to unreliable torque readings.The CheckStar rotary torque transducer forms an essential part of the Crane UTA torque system, enabling automatic transducer recognition with Crane readout devices. On board intelligence means the UTA CheckStar is automatically recognised by the Crane readout device, eliminating set-up errors and enabling logging of serial number against measurements for complete traceability. An Industry Standard (IS) version is also available where a user needs the advanced features of the CheckStar but already has a readout device from another manufacturer.

Key Features:

• Dynamic torque measurement of all continuous drive and impulse tools
• Proven reliable performance for impulse tool measurement
• Guaranteed no brush bounce
• Compact design and no size increase for angle option
• Automatic transducer recognition with Crane display systems (Auto ID)
• The new and improved version of the CheckStar rotay torque transducer, theCheckStar Multiis now also available with added features.

Product Details:

Crane’s static torque transducers are the quality choice for the testing of all continuous drive, impulse and hand torque tools in the workshop and production line-side environment.Stationary transducers are used off the production line in workshop or line-side test stations. Combined with joint kits that represent the production joint condition, the stationary transducers form an effective offline test for verification of assembly tool performance.

Stationary transducers enable Plug and Play operation with Crane readout devices and are automatically recognised, eliminating set-up errors and enabling logging of serial number against measurements for complete traceability. An Industry Standard (IS) version is also available where a user needs the features of the stationary transducer but already has a readout device from another manufacturer.

Key Features:

• Suitable for measurement of all continuous drive, impulse and hand torque tools
• Automatic tool recognition
• Combine with joint kits for workshop simulation of hard to soft joints
• Incorporate into custom built mobile test stations

Product Details:

Joint kits are an essential accessory for accurate off-line testing of powered assembly tools. The performance of an assembly tool is highly dependent on the conditions of the actual production joint on which it is used. Tooling engineers are well aware of the "mean shift" term used to describe the different torque delivered by the same tool when applied to a soft or a hard joint as defined by ISO 5393. It is therefore essential in testing and setting up tools off the production line to allow for the joint conditions which the tool will experience on the job.

Crane's joint kits satisfy this requirement by using a bolt and suitably configured disc washers allowing free running of the bolt and a subsequent torque gradient to closely match the production joint condition.

• Represent production joint conditions off the production line
• Adjustable to include joint conditions acc ISO 5393
• Allows free running of bolt before torque gradient
• Major benefit to accurate tool test and set-up
• Used in combination with stationary torque transducers or CheckStar rotary torque transducers

Two versions are available. Transducer Top joint kits are used in conjunction with female stationary transducers, while Table Top joint kits are used with CheckStar rotary transducers. The latter are fixed to a workbench and are particularly suitable for off-line testing of impulse tools. Both versions incorporate a selection of disc washers and spacers that may be configured to simulate various joint conditions.
