Torque and tension monitoring
A
Torque and tension monitoring Torque and tension monitoring of threaded fasteners is possible with the TNT system from Stewart-Warner Limited. With the system, separate transducers may be simultaneously connected to a portable readout instrument thus allowing direct comparison of the torque applied by a powered nut-runner and the resulting axial tension in a bo It. The instrument can operate either in a 'peak capturing' or a 'tracking' mode. The former allows instantaneous maximum values to be recorded; the latter can, for example, follow the relaxation of a joint after assembly. The system may therefore be used to establish optimum torque settings for particular fastenings, to calibrate torque-wrenches or to verify the performance of production tools in use. A ten-channel memory enables five pairs of torque and tension readings, or ten individual readings of either kind to be stored for subsequent analysis. There is also an auxiliary output socket for direct connection to a printer or computer. Inherent accuracy is claimed to be -+0.1% full scale. The 4'/2 digit display has a movable decimal point and can be adjusted between English and metric units.
the target and optimum results are obtained with ferromagnetic materials. For distances up to 5 m the sensor is connected directly to signal conditioning equipment via a coaxial cable. A range of signal conditioning equipment is available for single and multichannel measuring systems complete with peak value AC/DC converter, limit switches and peak displacement value storage. Trend and dynamic outputs are available which can be displayed on integral analogue or digital panel meters and fed to chart recorders.

series 7265 miniature accelerometers are designed to provide more accurate measurements of long duration pulses and are ideally suited for very low level vibration measurements of large structures, it is claimed. The model 7265 offers full scale ranges from 10 to 100 g. The units are fluid damped for protection against high level shocks and vibrations. Their design utilises two Endevco Piezite P11 silicon gauges in a half bridge circuit, providing a low impedance output of 500 mV full scale with 10V DC excitation. Bridge completion resistors are normally located in the signal conditioning equipment and allow shunt calibration of the transducer.

More modules Several modules have been added to the Eddychek Lab 2 eddy-current test instrumentation, available in the United Kingdom through Baugh and Weedon Limited (Fig. 2). To overcome problems which may arise when defective material has to be removed from the production line as it passes through the test coil, a new design of split coil has been developed. The upper half of the new test coil is hinged to allow for removal of the defective section and has been designed so that the signal loss between the two parts of the coil is effectively negligible. The coil is useful for testing high value products, such as titanium tube, as it helps to minimize the amount of scrap resulting from the defect. A second development is a module known as Thermocheck which enables the energy used in forming tube welds to be monitored. A small infrared sensor measures the temperature of the weld and provides a feedback to control the welding energy input to optimize the integrity of the weld. Eddycheck can also be used to monitor wire manufacture. An Eddycomp module has been developed for inclusion in systems for wire testing. The module is a miniature computer and recorder which produces a statistical analysis of defects in permanent print-out form. The resulting formal record of production performance can be arranged to include data such as heat treatment batch number, data and machine number. Other modules have been developed to enable all types of user to increase the flexibility of their system in

Faster and faster D J Birchall Limited have announced the latest addition to their range of piezo-ceramic accelerometers, the A/25/E (Fig. 4). The A/25/E is a subminiature accelerometer (10.79x6.35 x 4.70 mm overall) which weighs 1.5 g. Birchall's patented spigot-mounted 'Konic' design is incorporated into the accelerometer to give low cross axial sensitivity and minimisation of pyroelectric and base strain outputs. The resonant frequency of the device is 80 kHz and the maximum continuous acceleration 5000 g. The accelerometer is of an all-welded construction and will operate in tern-
peratures up to 250°C. It is designed for adhesive mounting and connection using Birchall's own sub-miniature microdot socket.

analysis
Gain and phase response of dynamic systems can be measured using SE Labs (EMI) Limited's SE2450 microprocessor-controlled frequency response analyser shown in Fig. 5. The analyser incorporates a standard program package to handle all commonly used dynamic test procedures so that test set-up time is minimised. Results of up to 120 tests can be stored in memory for subsequent display on the instrument's CaT screen. The SE2450 analyser operates within the 0.1MHz to 10kHz frequency range and can be used for bench testing or as an integral part of an automatic test system. The unit comprises a wideband, high-purity generator and two independent digital correlators. These basic elements are used to drive the system under test and to measure the gain and phase responses of the system at any two points simultaneously within the system.

The instrument has a sensing and display readout from one to 99% lower explosive limit and calibration is presettable for different flammable gases. The user has the option of continuous gas analysis or automatic pulse operation for multi-shift monitoring. In this mode, battery life and long term sensor stability are increased. The instrument's memory is updated at each sensing pulse. Any alarms are given at the end of each sensing pulse, or immediately if hazardous conditions occur in the continuous sensing mode.
