Monitran’s Group I intrinsically safe sensors are awarded ANZEx for use in mining applications in Australia and New Zealand.

All of Monitran’s Group I intrinsically safe accelerometers and velocity transducers have been approved by certification body Simtars to ANZEx for use in mining applications throughout Australia and New Zealand. This certification is in addition to the (EU) ATEX and (International) IECEx approvals Monitran’s Group I sensors already possess.

Andy Anthony, Monitran’s Operations Director, comments: “Many countries, whilst acknowledging international standards like IECEx, still impose their own standards for certain applications. We sought ANZEx in response to requests from end-users based in Australia and New Zealand, and companies based elsewhere wishing to supply machinery into these countries.”

Vibration AnalysisVibration is the response of a system to an internal or external stimulus causing it to oscillate. While it is commonly thought that vibration itself damages machines, it does not. Instead it is the damage done by dynamic stress that causes fatigue of the materials: the dynamic stresses are caused by vibration. That is to say that different machines have a different toleration to vibration.

There are literally hundreds of specific problems that can cause a machine to exhibit excessive vibration. To locate the root cause of vibration an analysis of the vibration is required. The forces that cause vibration are usually generated through the rotating motion of the machine's parts or electrical supply frequency. When a fault condition occurs the problem will exhibit characteristics that are directly related to these frequencies.

SENTRY G3
Condition monitoring specialists SENSONICS have introduced the Sentry G3 machinery protection monitor, a high performance signal conditioning unit. The new G3 monitor builds upon the established range of Sentry protection systems developed by Sensonics and is designed to be the most flexible and feature rich Turbine Supervisory System available. It provides a universal platform for the interfacing of various sensor types in compliance with the API 670 standard.

Each of the units four channels can be independently programmed to provide continuous monitoring and protection across a broad spectrum of measurement regimes, including vibration, expansion, temperature and speed. Sentry G3  utilises the latest DSP technology, so once a channel is set up and running, the resulting alarm relay and analogue output facilities are independent from the remaining module functionality, ensuring a scalable, high integrity configuration.

The M12 SensorHansford Sensors Ltd. has recently selected an alternative 12mm connector style, the M12, as offering the best combination of performance and price. The result - today, you can specify either the standard MS series or the M12 connector on most of their range of vibration sensors.

The main advantages of the M12 connector are its physically smaller size, associated cable assemblies have a tighter bend radius and it is a well accepted and proven connector used across many industries including process control, automation and sensing. They are particularly suitable for use in vibration monitoring equipment, the IP67/68 sealing making them usable in difficult environmental conditions often found in maintenance condition monitoring applications.

With its wide use in industrial electronic equipment, the cost-effective connectors and numerous cable assemblies are readily available from electrical distributors worldwide making 'off-the-shelf' delivery a reality.

Hansford SensorsHansford Sensors Ltd., the new sensor company formed in November 2006 has announced its first series of piezoelectric vibration sensors designed specifically to monitor the vibration levels on important plant and machinery across all types of industries.

These days, most Maintenance Engineers rely on sensors to detect increasing levels of vibration from bearings, shafts and other rotating components to warn them of inefficient operation or even possible future failure. This important knowledge allows them to maintain quality and avoid plant shut-down, with its inherent high costs.

The HS series of vibration sensors offer a choice of AC, velocity or 4-20mA outputs to suit differing applications. They are all built for robustness with their welded stainless steel construction, high shock tolerance and wide temperature operation range.
