Monitor and Analyse

• Fastener Tightness
• Torque/Angle profiles
• Torque/Time curves
• Manufacturing Process
• Pressure/Time
• Force/Displacement for press-fit analysis

The Model 846 collects and analyses data in many formats:

• Torque vs Time
• Torque vs. Angle (Position)
• Tension vs Time/Angle
• Pulse Tool Torque Tension profile
• Load cell data to analyse Press fit applications
• Displacement vs force
• Long term analysis of map or joint realisation
• 6 inputs for analog signals of 0 10 volts d.c. for use with d.c.d.t., string pots and other similar measurement devices.
• 8 digital TTL Compatible inputs for use with;
  • Trigger input
  • Monitor Digital Control Signals
  • External Sample Clock

The colour laptop computer provides instantaneous display of the recorded data. The data (curves) can be expanded and labelled with information to identify characteristics and features. Using the WINDOWS(TM) features, the data graphs can be filed or presented as many as 8 individual graphs on the same screen. The data can be printed as well as stored in a data file for future reference and comparison.

The TORKDUCER (non-contact) rotating torque sensors plug directly into the Model 846. Both the square drive and shaft to shaft series sensors can be used. Dynamometer tests and analysis as well as PULSE TOOL testing and analysis is possible with the Model 846.

The optional Joint Profile Simulator can duplicate a rotating fastener joint. The captured profile drives our patented Magnetorheological Brake to control a power tool exactly as the threaded joint would.

The Model 946 accepts all GSE Intelligent transducers, for automatic setup and calibration.

The WINDOWS based software program is extremely user friendly. It incorporates all of the features of WINDOWS (especially the wizard) along with many unique features for ease of setup and data collection.

The Model 846 is a digital data collector for all long term and instantaneous electrical and physical measurement signals.
