Wilcoxon Research has received Intrinsic Safety certification for two of its most popular low cost accelerometer series: the 786 and 787. These accelerometers are now rated to operate in hazardous areas in accordance with U.S. and Canadian standards.
Obtaining the Intrinsic Safety (IS) certification means that Wilcoxon’s 786 IS Series and 787 IS Series units can be used where flammable or explosive materials are present without causing electrical sparks or “hot spots” strong enough to cause ignition of gases or dusts in the air.
The 786 and 787 series are among Wilcoxon’s best selling low-cost accelerometers, and have actually met the standards of Intrinsic Safety for several years, but only recently were submitted for testing and received certification.
The 786 IS Series of top exit accelerometers includes an integral cable model (the 786F) and the first dual output accelerometer with temperature sensor to receive IS certification (the 786T). The 787 IS Series are side exit units, and include an optional modified mounting stud.
Wilcoxon 786 IS series and 787 IS series are certified as Intrinsically Safe for Class I, Division 1 rated for Groups A, B, C, D; Class II, Division 1 rated for Groups E, F, G; Class III, Division 1; Class I, Zone 0, Ex ia IIC T4 (zone approval for Canada); and Class I, Zone 0, Aex ia IIC T4 (zone approval for US). European approval is pending and expected by March 1, 2005.
