The four-channel Sentry G3 overspeed protection system from condition monitoring specialist Sensonics has been specifically designed with an independent digital signal processor (DSP) for each channel of measurement. The DSP can be software loaded with the specific measurement algorithm, which not only controls the sensor selection but also the protection relay status and analogue output levels.

Tech Byte: know your emissivity download
The material emissivity is the relative power of the material’s surface to emit heat by radiation. Materials are assigned an emissivity value between zero and 1.0. Emissivity is a measure of a material’s ability to emit infrared energy. As IRISS explains here, the emissivity of a surface is the ratio of the energy radiated from it to that from a blackbody at the same temperature, the same wavelength and under the same viewing conditions.

Micro-electromechanical systems (MEMS) have come into wide-scale use in the last few years, and the trend does not appear to be slowing down. In industries such as automotive and consumer electronics manufacturing, there is a growing use of accelerometers and gyroscopes being seen. This article from Sherborne discusses the manufacture of MEMS sensors.
There are a host of possible explanations that might help explain seemingly contradictory study results, according to Minitab. Perhaps the studies utilised different designs, different statistical methodologies, different survey techniques, different confounding variables, different clinical endpoints or different populations. Or perhaps there’s something even more fundamental at play. The proverbial elephant in the room of any statistical analysis. The essential, pivotal question upon ...
The purpose of this paper from IRISS is to educate on the subject of transmission values for infrared windows — does a high value equal more accuracy? Or is knowing the percentage of transmission more important? The paper also discusses transmission values for infrared windows: how does a ‘grill’ affect transmission? Will it make quantitative thermography null and void?
The materials available for infrared (IR) window optics are diverse and have a variety of transmission rates and mechanical strengths. It is advisable that when considering the use of IR windows, you seek advice from IR window manufacturers and IR lens material suppliers before deciding the materials and window styles best suited to your application.
Electrical accidents happen daily; however, there are steps that companies and individuals can take to reduce the occurrence of these accidents and protect everybody concerned from the consequences. The National Fire Protection Association provides, in its regulation 70E, a reference for facilities to meet the requirements of electrical workplace safety and its regulation 70B outlines the best practices for setting up and maintaining an electrical preventative maintenance programme.
You are correct when you state that the grill will affect your measurements. In fact, all infrared (IR) window lenses affect the transmission rate of the target temperature. Regardless of the type of IR window you are using, you need to test and adjust your IR camera for the transmissivity of the lens material you are using. This value can vary by camera even if it is the same make and model of camera. This is due to differences of the detectors in the IR cameras.
