Machine Vibration Monitor protects machinery in rugged environments

Milwaukee, Wis. – To provide cost-effective and continuous vibration monitoring and protection for industrial machinery, Rockwell Automation introduces the Entek Sentinel. The Sentinel can be placed directly on a vibrating surface to insure machines operate within acceptable limits and/or to alert plant personnel to potentially harmful levels of vibration.

Most commonly applied to machines such as industrial centrifuges and rock grinders, the Sentinel’s rugged design can withstand harsh environments to insure that continuous machine operation is maintained and production levels met. Its all-in-one construction makes it particularly well-suited for applications in which dirt and grime may interfere with operations, such as machines in the oil and gas, cement, power, or petrochemical industries.

‘In industries where continuous performance directly affects profitability, an unplanned shutdown can result in significant lost revenue,’ says Pat Carle, product manager, Rockwell Automation asset management business. ‘By monitoring the vibration level of machinery, the Sentinel can help end-users maximize the productivity of their assets. It helps our customers keep their equipment running, maintain output levels and meet production deadlines.’

All Sentinel parts, including its microchip-based accelerometer, are contained in a durable enclosure, making it more cost-effective than using external monitoring components. Designed to withstand temperatures from -30 to 70 degrees Celsius and continuous vibration up to 50g, the unit offers performance reliability under the most extreme operating conditions. The single-channel Sentinel is ideal for field applications in which a simple mechanical vibration switch is insufficient, yet a more comprehensive and expensive monitoring system is not necessary.

The Sentinel, used in both attended and remote locations, can be configured as a standalone unit or integrated with a control system, via its standard 4-20mA or buffered outputs, or its optional DeviceNet interface.
