ANALYTICAL INSTRUMENTATION

NEW Radiometric Density System

diverse operator interfaces. Operators ben- efit from the new simplified user-friendly interface where calibration is as simple as possible. Only two-points – a low and a high density, e.g. air and water – have to be acquired by the customer. Advanced self-diagnostics and monitoring features ensure a safe function of the system. Operators also benefit from the new service functionalities like data logging, which can be accessed either remotely through Ethernet connection or through the USB port at the front panel of the sys- tem.

The measuring system DuoSeries stands out by a particularly excellent performance with high accuracy and repeatability. De- pending on customers' needs, the trans- mitter output can be configured for units of specific gravity (SGU), ‘pounds per gallon’ (PPG), or a calculated ‘pounds proppant added’ (PPA).The DuoSeries density meas- uring easily connects to the FracSENS LB 6770 detector and links directly to the cus- tomer control system. No calibration or dif- ficult math has to be implemented in the data system. The density gauge is used to translate the measured count rate into the specified output values either in low pres- sure or in high pressure applications. The density transmitter is a state-of- the-art control unit with robust 3,5” TFT touch panel, powerful Dual Core CPU, and

DuoSeries LB 475 is the new radiometric density system from Berthold especially designed for the cementing and hydraulic fracturing industry.

TorqSense … for caps that fit

Strict international rules apply to the manufacture and packaging of pharmaceutical products and require that the correct environment is maintained within the bottle following capping. Regulation USP 671 provides a guide to the torque range to be used for screw type containers with varying closure diameters. By ensuring that bot- tle caps are successfully applied to the bottles within the required torque tolerances, the integrity of the product is maintained. Sen- sor Technology Ltd, which makesTorqSense, has worked with many

OEMs to develop high precision, high speed capping machines for use in pharmaceutical plants and a range of other applications. One of these, Cap Coder, an Oxfordshire neighbour of SensorTechnology, incorporates TorqSense units in its CC1440 and CC1440T Bench top Cap Coder machines, both of which are used by the Almac Group. TorqSense is wireless and does not need to physically contact the bottle caps or shaft of the torque head it is monitoring. Sensing is achieved through a radio frequency link.

Attached to the surface of the transducer shaft are two Surface Acoustic Wave (SAW) devices, when torque is applied to the shaft the SAWs react to the applied strain and change their out- put. The SAW devices are in- terrogated wirelessly using an RF couple, which passes the SAW data to and from the electronics inside the body of the transducer. “All you have to do is set up a TorqSense transducer in the capping machine and turn it on,” explains Mark Ingham of SensorTechnology .
