Compressed Air Energy Savings- Find Wasted Cash
it a much more effective technology for today's compressed air applications. Compressed air is a "Killer Ap" for thermal mass flow meters because of accuracy, turndown, and easy single point insertion. High accuracy of 1.0% of reading and large turndown ratios are critical in assessing a facility's baseline compressed air usage. Turndown is a thermal mass flow meter's biggest asset in this application. With a true 100:1 turndown, a single Sierra meter has the flexibility to accurately measure not only... (read more)

First Sensor AG
X100-7 Detector for Gamma Radiation
With its active area of 100 mm² it provides a large cross section for radiation detection. A special black epoxy encapsulant guaranties the blocking of light while maintaining small gamma ray attenuation (see Figure). Recent events like the nuclear disaster in Japan have raised awareness of risks from nuclear radiation and created a demand for commercial as well as personal radiation detection devices. Nuclear radiation meters based on silicon solid state detectors such as the X100-7 provide... (read more)
