ANALYTICAL INSTRUMENTATION

ROUND UP

New scope offers top signal visualisation TEKTRONIX represented in SouthAfrica by Comtest , has launched theTBS2000, a next generation basic oscilloscope featuring the longest record length and largest display in its class for faster signal evaluation and troubleshooting.This latest addition to theTektronix portfolio puts expanded capabilities, including the ability to use a wide range ofTektronix probes, into the hands of budget- constrained design engineers and educators.  Building on the success of theirTDS2000 Series, the most widely used os- cilloscope in the world, the newTBS2000 gives users a level of design insight previously not available in this class of instrument. The new instrument also sets a new standard for usability with features like a large display for easy signal visualisation and a comprehensive set of automatic waveformmeasure- ments that are coupled with graphical explanations to help engineers better understand their measurements.  Design engineers use general-purpose oscilloscopes to prototype, debug and validate designs of new products and for general troubleshooting. In education, such oscilloscopes give students hands-on experience in electron- ics engineering and educators need to efficiently mentor and monitor large groups of students.

Vibration and temperature monitoring in one Vibration and temperature are the most common parameters used for machin- ery protection. Of these, temperature has been used longer, probably because it was available first and was better understood than vibration analysis. However, it is now stated that vibration is the better measurement over temperature because it gives an earlier warning and more information as the vibration signal contains many frequencies and many amplitudes, each pertaining to some moving part of the machine. The latest units available in the RC range, available from R&C Instrumenta- tion , combine these two parameters and provide protection of critical plant from high temperature and high vibration levels.The unit consists of a 2-wire 4-20 ma output to monitor vibration levels and a dc voltage output that has a 10 mV per °C directly proportional to the measured temperature and not an inferred measurement of the vibration.

Different velocity (mm/sec) ranges, process connection and electrical connections are available.The standard unit, which covers most applications, would have a vibration range of 25 mm/sec RMS, an 8 mm stud process connector and a 3 m cable connection.The unit’s environmental rating is IP 67 and it has a case material of stainless steel with a top cable entry.
