This company now offers an intrinsically safe Bluetooth module for wireless transmission of measured data from its laser shaft-alignment systems. Now it is possible to work wirelessly in explosive environments. Using the Bluetooth module eliminates the use of cable connections between the sensor and the handheld computer, making alignment jobs easier, says the company. The intrinsically safe alignment systems Optalign smartEX and Rotalign smart EX (photo) with the new Bluetooth module are now available. All active measurement components comply with ATEX and IECEx directives for Class II 2 G Ex ib (ib) IIC T4, Zone 1. — Prüftechnik Alignment Systems GmbH, Ismaning, Germany
