Our business is protecting yoursPower Generation, oil and gas production and distribution, petrochemical processing, gas turbine marine propulsion — these are typical areas where high-value,critical rotating machinery is employed. Safety has always been a major issue and protection systems, including vibratio parameters, are frequently mandatory. 

Main features and benefits Traditionally, separate systems have been provided for machinery protection, on-line condition monitoring, and machinery performance assessment. However, the VM600 Series uses the latest digital signal processing technology–and industry standard communications interfaces — todeliver the most up-to-date, integrated, modular, scaleabl solution to all machinery protection, condition and per formance monitoring requirements, within a single system framework. Only two types of signal processing modules are required — one for protection and one for condition and performance monitoring data acquisition. Each card can perform all of the necessary signal processing tasks, with input from any appropriate sensor, simplifying specification, installation, training and spares holding. 

¥ All monitoring functions (absolute and/or relative vibration, dynamic pressure, displacement, orbit, Smax, position, expansion, etc.) available on a single card

 ¥ Communications over Ethernet or serial links using standard protocols

 ¥ Remote configuration, interrogation and support

 ¥ Local display of levels and status

 ¥ Protection functions independent of condition monitoring functions

 ¥ API-670 compliant 

¥ Comprehensive voting logic combinations

 ¥ Cards are hot-swappable

 ¥ Dual redundant power supplies and communication links

 ¥ One 6U rack accommodates up to 48 protectionchannels or 192 condition monitoring/process inputs.

 ¥ “Platform independent” software –WindowsTM NT/2000,SCO Open Server (UNIX), Linux

DYMAC total system capability

 SENSORS & SIGNALCONDITIONING

 Afull range of industrial accelerometers, velocity transducers, eddy current probes, dynamic pressure sensors, air gap

 sensors, and ice detectors for high temperatures and other harsh environments.

 MACHINERYPROTECTION SYSTEMS

 Fully autonomous protection systems for instant detection of machinery problems. Protection for both excessive

 vibration and over-speed conditions. A single universal card accepts input from all dynamic and static sensors, and

 provides a comprehensive array of processing and voting logic, with analogue, DC and digital outputs to other systems. 

MACHINERYCONDITION MONITORING

 On-line and off-line hardware and software solutions for prediction of machinery problems in advance. Automatic high

speed detection of run-up/ coast-down and ’upset capture’ data, 16 channel parallel data acquisition cards, all dynamic

 and static inputs. Sophisticated Condition Monitoring software for machinery monitoring and analysis, including

 continuous streaming technology, logging by exception, interfaces to portable devices and DCS systems, and a full array

 of diagnostic tools such as Fast Fourier Transform (FFT). Remote access over modem, network or internet. Specialised

 applications including hydro turbines and reciprocating compressors.

 MACHINERYPERFORMANCE MONITORING

 Basic Package — manual or automatic data entry, simple performance calculations and trending of aero thermal

 parameters.

 Advanced package — automatic data entry, modelling refined with experience, comparison of actual against expected

 performance giving a true online picture of machinery behaviour for decision support.

 Maintenance Optimisation — fuel used, emissions, calculation of emission taxes, parts life calculation for hot com

ponents, predicted and measured calculation for maintenance actions
