Proximity Sensors detect an object without touching it, and they therefore do not cause abrasion or damage to the object. Devices such as limit switches detect an object by contacting it, but Proximity Sensors are able to detect the presence of the object electrically, without having to touch it.
The transmitters provide a 4-20 mA output signal proportional to the vibration velocity, across its frequency range. The output signal can be transmitted to common process control systems like PLC, DCS, and SCADA. The transmitters operate using power from any standard 4-20 mA loop.
A vibration meter is used in manufacturing for machine condition monitoring, product testing and quality assurance. Many machine maintenance technicians use vibration meter devices in tandem with sound level meters to analyze frequency.
Vibration monitoring systems are used for condition-based maintenance of machines and installations. They help to detect machine damage in good time and prevent costly consequential damage. ... Vibration transmitters and sensors detect damaged bearings and unbalance in drives and rotating machine parts.
Vibration analysis is a process that monitors the levels and patterns of vibration signals within a component, machinery or structure, to detect abnormal vibration events and to evaluate the overall condition of the test object. The equipment used to monitor all the data to analyze is called Vibration Analyzers.
Vibration Switch is working according to the pendulum switching principle. A swinging permanent magnet holds a magnetic switch situated below in a particular position. Due to vibration, the magnetic field between Reed Switch and magnet changes. Thus the switch is actuated resulting in the stoppage of the equipment.
The reverse rotation monitor (RRM) is used for the protection of important machinery like Boiler feed pumps, Turbine, Horizontal and vertical pumps, compressors, crushers, etc. against reverse rotation. It provides an early indication of reverse rotation events. Finds applications in machines having fluid couplings wherein bearing damages can be avoided by using RRM.
This unit also can be used as Start Premissive contact during reverse rotation in vertical or horizontal pumps. Motor or pumps can not be restarted unless and otherwise reverse rotation /flow drops to an acceptable range.
