As a result of gaining the highest standard for intrinsic safety ATEX (EEx ia), the established range of PZS accelerometers can now provide an even wider scope of applications. The PZS device has been used throughout industry for machine vibration monitoring of motors, pumps and power turbines in potentially explosive atmospheres. The recertification now permits use on an extended range of gas turbine sets. The PZS enables safe operation in the event of two component failures in a hydrogen atmosphere, and this performance has been extended to include operation up to 100°C with a maximum loaded capacitance rating of 47 nF for Class IIC environments in a 28.5-V circuit. Applications include installations where cable runs in excess of 400 m can be achieved. — Sensonics Ltd., Berkhamstead, U.K.
