May 5, 2014 – Marsh Bellofram announced WESTCON 758-9910001 industrial AC tachometer generator. These highly rugged, explosion-proof devices can effectively support the demanding predictive maintenance requirements of aerospace, oil and gas drilling, industrial mud pumps, and waste and wastewater pumps and systems, with complete and efficient 24/7 rotational speed monitoring. The tachometer is especially beneficial for rotary table RPM and mud pump SPM, two of the primary parameters for achieving maximum drilling efficiencies. WESTCON 758-9910001 AC tachometer generators are designed to convert rotational shaft speed inputs into a linear analog voltage output, even in the harshest of environments.
The tachometers feature a standard ¾” drive shaft, with only a 3.0 oz-in starting torque. Their components are housed within a explosion-proof case that is ATEX certified for Class 1, Division 1, Class 1, Group D and Class 2, Groups F and G. Series units are also UL listed. In addition, their rugged, bearing-free and brush-free design requires absolutely no maintenance for increased reliability and minimal downtime.
