Affordable intelligent protection for smaller rotating plant

Continuous protection and monitoring is becoming an essential requirement for critical rotating plant across industry as part of the process of improving efficiency, reducing energy consumption and eliminating downtime. Whether generating power, pumping essential fluids or driving process equipment, it is vital that machinery dynamic behaviour is monitored and processes are protected from the disruption and expense of unscheduled downtime.

Typically the higher cost of more sophisticated protection systems can be difficult to justify for smaller machinery operating on less critical applications, although the requirement for monitoring still needs to be addressed. Sensonics says the solution to this problem is its cost-effective and compact DN26 G3 machinery protection monitor.

The high-performance DN26 G3 machinery protection monitor mounts on DIN rail and offers fully programmable signal conditioning with a range of measurement algorithms and sensor modes, including absolute vibration, relative vibration and shaft position (or thrust bearing wear). In addition, the module offers a dedicated speed monitor channel that can also be utilised as a phase reference for harmonic analysis of the vibration signals.

Sensonics says the DN26 G3 high-performance machine condition monitoring module is capable of monitoring two channels of bearing vibration, shaft vibration or shaft position and offers fully programmable signal conditioning with a range of measurement algorithms and sensor options. In addition the DN26 G3 offers a dedicated speed monitor channel that can also be utilised as a phase reference for harmonic analysis of the vibration signals. The unit is designed for optimum flexibility; as a universal module (single hardware platform) it is field-upgradable and can be programmed for any of the measurement options detailed above. It is available with mains or +24V power supply options.

Compatible sensors

The sensor interface is programmable to accept IEPE type accelerometers/velometers, proximity probes (API 670 standard), and active/passive speed probes.

All sensor signals are available via a buffered interface that provides the option of further detailed analysis if required. Three alarm relays are available (expandable to up to seven relays via a digital interface), one dedicated to indicate module and sensor integrity, while the other two relays are fully programmable across the alarm criteria selected. All three input channels' measured values are available via a 4-20mA interface.

The DN26 G3 is equipped with Ethernet communications as standard, permitting configuration either locally or remotely through the inbuilt web server; Modbus over TCP/IP is also available for transmitting measured data to other plant-wide systems.

Each DN26 G3 machinery protection module features a built-in intuitive colour LCD display and menu-driven facility providing various display modes including FFT analysis of the dynamic channels and an alarm historian with real-time logging capability.
