Protection Monitors

Sensonics vibration monitoring systems offer a range of both contact and non-contact techniques for accurate measurement of absolute and relative vibration on critical machines and infrastructure. Our sensors are available in a range of output configurations (acceleration, velocity or 4-20mA); combined with our established vibration monitoring and protection equipment they offer high integrity measurements with flexible alarm facilities.

Sensonics Vibration Monitoring Systems

Our sensor range includes accelerometers, velocity transducers and eddy current proximity probes, so whatever your vibration monitoring requirements, we have a solution to fit, backed up with over 30 years field experience.

Sentry G3 (Universal Input) Monitoring and Protection System

The Sensonics Sentry G3 concept builds upon the established range of Sentry products developed by Sensonics and has been designed to be the most flexible and feature rich machinery protection system available. Each of the G3 module’s four channels can be independently programmed to provide continuous monitoring and protection across a broad spectrum of measurement regimes, including vibration, position, temperature and speed, providing a universal platform for the interfacing of various sensor types in compliance with the API 670 standard.

The unit has an integral intuitive colour LCD display and drive facility which provides immediate viewing and access to the machines parameters. Several modes of display are available to suit specific applications, such as an alarm historian and parameter trending per channel. The G3 system offers excellent channel density with up to 24 measurement channels in a 3U format, also each channel can provide independent analogue outputs of current and voltage for PLC connection. The system is designed for mounting in a custom 19” rack assembly which also contains a dual redundant power supply option. The Sentry G3 system algorithms are particularly suitable for large turbine generator sets where the vibration monitoring forms part of the essential Turbine Supervisory System.

Aegis Monitoring and Protection System

The Aegis system offers similar measurement capabilities to Sentry but in a lower cost rack mounted package. A range of units are available offering standard absolute and relative vibration measurements; a special bearing condition option is available incorporating an enveloping technique for roller bearing applications.

The system utilises a shared display located in the instrument rack with single channel cards for each of the required measurement channels. The Aegis monitoring system is suitable for a range of rotating machinery including turbines, motors and pumps where individual channel displays are not required (closed equipment cabinets, unmanned sites, etc). Other measurement modules include displacement, expansion, temperature and speed in addition to the vibration monitoring options. This technology is also available as a single channel unit (MO9601) in a wall mounted enclosure for standalone applications.

DN2601 Datasheet

DN2601/02 Vibration Monitoring and Protection unit

The DN26 range of DIN rail mountable vibration monitors are compatible with a range of transducer types to suite most vibration monitoring applications. This compact single channel unit offers dual level alarms (positive and negative going) in combination with 4-20mA outputs for PLC or DCS connection. The DN2601 is designed to work with a wide range of 2 or 3 wire accelerometers & velocity transducers to provide flexible monitoring and protection over a wide range of vibration parameters. The DN2602 is suitable for connection to API670 eddy current proximity probe systems for the measurement of peak shaft vibration.
