What type of system would you prefer to protect your critical rotating plant?

  • I want a fully programmable system
  • I want one module type for all measurements
  • I want a sensor interface that’s totally flexible
  • I want a system that utilises individual processors per channel which are independent from other hardware
  • I want a colour LCD display providing alarm history plus an FTT display of the dynamic channel
  • I want an API 670 compliant system

The need to protect your critical plant and equipment

Continuous protection and monitoring is an essential requirement for critical rotating plant in many areas of industry. Whether you are generating power, pumping essential fluids or driving process equipment – it’s vital to monitor the machine dynamic behaviour through the measurement of vibration, speed, expansion and temperature, in addition to other parameters. For over 40 years Sensonics has been at the forefront in developing the most sophisticated condition monitoring systems and products which help industry to monitor and protect critical rotating plant.

A proven track record From its Hertfordshire, UK base Sensonics is proud of its reputation as a leading manufacturer of condition monitoring systems. This is underlined by the ongoing success of the innovative Sentry G3 system which represents the third generation of the Sentry concept – evolved from 40 years of real world applications.

The Sentry G3 Machinery Protection Concept is a rack mounted, high performance sensor conditioning and monitoring system. It provides a universal platform for the interfacing of various sensor types to meet with the demanding application of rotating machine protection.

The high-performance sensor conditioning and monitoring system

Features and Benefits

Sentry G3 is designed so that each plug-in module provides up to four measurement channels. These can be independently programmed to provide continuous monitoring and protection facilities across a broad spectrum of sensor regimes (including vibration, expansion, temperature, speed and position).

Independent Alarms – High Integrity
Utilising the latest DSP technology, once a channel is configured and running, the resulting alarm relay and analogue output facilities remain independent from the
other module functionality.This results in a scalable, high integrity configuration suitable for IEC61508 applications.

Immediate Viewing – Easy Access

Each module is provided with an intuitive colour LCD display and menu drive facility to provide immediate viewing access to the machine parameters. Several modes of display are available including bar graph, FFT an alarm historian.
