7 Reasons Why You Need the Sentry G3 Sensor Condition Monitoring System for Your Power Plant – Part 1

Sensonics Sentry G3 Monitoring and Protection System

Sensonics Sentry G3 Monitoring and Protection System…For all your Condition Monitoring needs!

 

The Sentry G3, high performance machinery protection and condition monitoring system is used for a wide range of functions in the Power Plant Industry, these include; shaft position, high / low pressure, cylinder expansion, turbine block expansion, shaft vibration, eccentricity, and speed. 

Applications

The Sentry G3 system is capable of monitoring a number of variants. For example, shaft position measuring and monitoring, relative to the position between the machine shaft and the journal or hydrodynamic bearing surface. The system also automatically protects the critical machines in your plant when the relative position is over the pre-set level. Specifically, the machine train will be stopped when the shaft moves within the bearing clearance towards say towards the generator side of a turbo generator set, by an excessive amount, such as, for example 1.2mm or when the shaft moves to the turbine side by 1.7mm (-1.7mm to + 1,2mm). Other variants include; axial thrust position, high and low pressure cylinder expansion, a variety of process data; such as bearing temperatures, pressures and flow rates, with each requiring an alarm signal.

With the above applications in mind, please find below 7 key features of the Sentry G3 and how these can benefit your Power Plant and outperform any other machinery protection and condition monitoring system on the market:

1.  Sentry G3 Programmable Modules

The Sentry G3 contains modules and plug/play DSP channel cards. Hence, there is no requirement to decide measurement type (abs vib, rel vib, disp, temp, process) prior to purchase.  Meaning, the customer can purchase the exact monitoring unit as required i.e. 1, 2, 3 or 4 channels per module of any machinery monitoring type without unused spare channels. This in turn saves costs and increases flexibility as channels can be simply added by the customer in future as required.

Competitor systems require purchase of complete modules e.g. all four 4 channels, rather than the required number of relative vibration channels actually needed per module.

With programmable modules, this is also advantageous, as the customer can hold spare stock of ‘blank’ G3 modules and DSP cards/channels. Having the blank units in stock means the customer will not have to wait for spares delivery from the manufacturer (which can be between 4 – 6 weeks from a major competitor) in the event of the replacements being required.  Also, a reduced spares inventory can be held as all modules and DSP cards can be configured individually by the customer for any measurement mode.  It must be noted that holding stock of specific and dedicated modules is expensive.

Finally, with the programmable modules, these can readily be upgraded by the customer (using simple freeware, standard laptop/USB), as programming of modules/DSP cards is a simple process.  This of course helps reduced costs (equipment supplier engineer rarely required) and reduced project time as the in-house engineer can perform this tasks as opposed to waiting for a 3rd party/equipment manufacturer engineer, to carry out this task.

Competitor systems often require an engineer to be sent to site for this and carry out modifications via dipswitches etc.

2.  Programmable Alarms (Warning and Danger Levels)

These ensure the system can be adjusted to meet specific customer requirements and not those specified by other industries. These types of protection systems are typically designed for the power industry, but are equally applicable for other industries.

3.  Low Pass Filter, HPF, Tracking and Notch Filters

As above, this ensures the system can be adjusted to meet specific customer requirements and not those specified by other industries.

4.  Independent Channel/DSP Cards

Should one DSP card/channel fail then this will not affect other channels within the module or wider system.  This reduces the risk of overall system downtime and blank DSP cards can be held in stock locally for immediate replacement.  Competitor systems will require a complete module swap should a channel go down.

5.   API670 Compliant

The customer is assured the G3 will work with industry standard sensors and to the required overall specifications. This gives the customer confidence in the equipment performance and also reduces costs in a retrofit e.g. where existing sensors are required to be connected to the protection system.

Competitor systems often require an engineer to be sent to site for this and modifications via dipswitches etc.

6.  Open Source Data Output 

The G3 will communicate with other open source software packages (typically via buffered outputs on rack rear panel) used for data analysis, storage and condition monitoring. This increases customer choice, thus potentially reducing costs.  It also enables the customer to continue with their preferred analysis software (if open source type).

A certain competitor is now going down the route of using proprietary data comms. Hence, the customer will be locked in to that competitor’s hardware/software if they go down this route…

7.  G3 Module Power Independent

The G3 modules are powered independently; therefore if one module fails others will not be compromised. Hot swaps of modules can be performed, reducing service times and reducing risk of total system down time and therefore loss of production.
