This category covers:
Instruments and devices used by engineers to determine the scope, quantity or extent of a particular item; to assess that it meets certain criteria; or investigate whether it is in proper working order. Includes environmental testing, vision, sound and vibration testing, position and proximity testing, force strain and speed testing, electrical testing, non-destructive testing and metrology systems.
Renishaw’s TONiC linear and rotary (angle) encoder systems feature integral setup LEDs that are usually sufficient for installation purposes, giving a visual indication of the signal level and calibration status. Customers with the most challenging setup requirements are supported by an optional PC software package for use in conjunction with a diagnostic hardware kit.

As the saying goes, ‘garbage in, garbage out’. This truism is every bit as applicable in thermography as it is in computer data mining. The difference is that the inaccurate data that leads a thermographer to a false-negative conclusion could result in a multimillion-dollar catastrophic failure of a company’s electrical distribution system. In fact, the implications to personnel safety, plant assets and production downtime make the results of transmissivity errors more like toxic waste ...
The National Fire Protection Association (NFPA) was established in 1896 and has become the world’s leading advocate of fire prevention. The influence of its 300 codes and standards are evident in buildings, products and practices throughout the world. NFPA codes are adopted through a broad consensus of experts, and have resulted in some of the world’s most referenced and respected codes. This white paper from IRISS explores NFPA 70, also known as the National Electric Code (NEC), which ...
With between 70 and 80 per cent of all hydraulic failures caused by contaminated oil, effective analysis is vital to ensuring the healthy functioning of machinery. Bosch Rexroth outlines its top 10 tips for maintaining oil quality.
In this white paper, Martin Robinson, a Level III thermographer and chief executive officer (CEO) of IRISS, discusses the history of infrared windows. He said: ‘As CEO and founder of IRISS, I am often asked how and why I designed our product line the way I did. As is common with such product development processes, there was no single epiphany that unveiled today’s design to me. Instead, I arrived at our best-in-class design through an evolution of enhancements, each improving on the ...
Electrical accidents, such as arc flashes, happen daily; however, there are ways companies and individuals can reduce the occurrence of these accidents and protect everybody concerned from the consequences. The NFPA regulation 70E provides a reference for facilities to meet the requirements of electrical workplace safety, while regulation 70B outlines the best practices for setting up and maintaining an electrical preventive maintenance programme.
Laser interferometers are often assumed to automatically provide the ultimate in measurement accuracy. However, in reality, the situation is more complex. When measuring linear displacements in air with a laser, the performance of the environmental compensation system is particularly important. The laser and interferometric measurement optics provide very high levels of linear resolution and precision, but it is the environmental compensation unit (weather station) that is primarily ...
What’s the point in installing crystal infrared windows to allow live thermal-imaging inspection when the nature of the product will simply de-rate critical electrical switchgear in which they are fitted? This type of window is often chosen because the specifier believes it to be the only product suitable for visual as well infrared inspection. But in common with all visual viewing panes, crystal windows also need to meet stringent safety and performance standards for industrial use.
The insulation of rotating machines has to withstand thermal, electrical, ambient and mechanical (TEAM) stresses during its service lifetime. According to OMICRON electronics, partial discharge (PD) measurements applied to coils and complete stator windings detect manufacturing defects and also insulation degradation caused by ageing processes. To detect insulation degradation at an early stage and to prevent severe failures in service, detailed information on the actual insulation ...
