Hansford 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.

A petroleum storage depot in Essex providing essential fuel supplies to various outlets across East Anglia needed some updating of its condition monitoring system; predictive maintenance system specialists, Sensonics Ltd were called in to update the facilities and to retrofit an improved vibration detection system.

Hansford 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.

A full specification truly portable vibration analyser at an affordable price!

Because it is based on Pocket PC technology, Pocket VibrA Pro is able to combine exceptional processing power with ease of use to offer the ultimate in portable vibration analysis.

Pocket VibrA Pro combines asset management, data collection and analysis together with 3 level colour-coded alarm indication in a rugged vibration meter that fits in your pocket.

All data is held in a shared database format which allows easy viewing of data or asset configuration to be performed on the Pocket PC or a desk top. Synchronisation is automatic via the PC docking cradle and the included FreeTrendTM software allows full trending of all asset data as well as automatic report generation.

Vibration 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.

 

 

Vehicles can be rented, so can tents and even Santa Claus outfits. It's probably less well known that when air-conditioning or power-supply units are required, they too can be hired rather than purchased outright. One of Europe's biggest providers in this area is Energyst B.V., with their head office in Breda, the Netherlands.

Energyst B.V. always have the right solution available when it comes to equipment for generating electricity, refrigeration, air conditioning, or heating and ventilation. Caterpillar electricity generators start at 20 kVA and go right up to complete installations for power stations. Besides electrical generating sets, Energyst also supplies uninterruptible power supplies (UPS), transformers, load banks, switch over panels, distribution panels, and cables.

The collaboration between Degussa and Energyst is very varied in its nature. Within the framework of the expansion of the public utilities, linked with the construction of the new Methionine factory in Antwerp, Energyst offers support by means of temporary heating and cooling equipment.

In consultation with the central energy unit, and their German colleagues, Energyst supplied several back-up central heating boilers during the expansion work carried out within the gas supply system.

Cool Energy can offer you a nationwide same and next day delivery service to help you with any unplanned Chill Store breakdowns and emergencies. Cool Energy are refrigeration specialists providing RENTAL low temperature fan coils and chillers, capable of being supplied to help provide sub 4°C air temperatures fast, whilst your breakdown is being repaired.

We can provide you with express delivery, installation and commissioning service alongside the supply of flexible water hoses, pipework connections, heat exchangers and power generators.Need a small or large cooling package now?
