ROUND UP

New generation Ex isolated barriers and Ex analogue signal isolators Turck, supplied locally by RET Automation Controls , has released the IMX12 device series, a new generation of Ex isolated barriers and Ex analogue signal isolators. With its compact and slim 12,5 mm hous- ing, the device series offers maximum signal density.This now enables 2-channel temperature measuring amplifiers in 4-wire PT100 circuits to be implemented via up to four 2-pole terminals – each on the Ex and non-Ex side. Besides the signal density, the IMX12 devices stand out on account of their speed, accuracy and flexibility. previously the reserve of special frequency transducers, can be transferred reliably. With up to 15 000 Hz, measured values can be optimally resolved and allow precise measuring without the negative effect of a signal conversion. The developers have given special con- sideration to the increased requirements with regard to precision:The new electronic design enables the effects of factors such as temperature or voltage fluctuations to be reduced on the IMX12-AI Ex analogue signal isolator. The effect of the interface device on the overall performance of a com- plete measuring circuit is thus considerably less than usual. The devices of the IMX12 series can be used seamlessly in a range from10 to 30Vdc.This opens up new possibilities, for example, with a battery or PV current supply. Enquiries: BrandonTopham.

Early warning signs

BMG offers the full portfolio of SPM condition monitoring equip- ment, from basic hand held instruments, to high level on-line sys- tems. Included in this range is the entry level VibChecker portable instrument, designed for reliable on-site vibration measurement and assessment. “TheVibChecker requires minimal operator training and supports BMG’s BearingChecker which is used to accurately assess the condi- tion of rolling element bearings during operation in equipment like motors, fans, pumps and gearboxes,” says Carlo Beukes, General

Manager: Drives Belts & Ironware divisions, BMG – Bearing Man Group. “The VibChecker gives early warning signs of developing machine problems in order to prevent premature replacement of machine parts. Vibration monitoring is the most widely used pre- ventative maintenance technique for the accurate assessment of the condition of machinery elements – like pump rotors, fan impellors, gearbox gears and housing mountings.
