Power electronics is a technology that deals with the conversion and control of electrical power with high-efficiency switching mode electronic devices for a wide range of applications.
The selection and use of flammable gas detectors. Calibration gases. 45 Ideally, the gas to be measured should be used to calibrate the gas detector. Calibration of fixed and portable gas detectors is normally done using a calibrated. gas mixture from a cylinder, supplied by a gas company.
5.0 RADIATION MONITORING SURVEY INSTRUMENTS Radiation survey instruments are used to detect potential radiation hazards, measure radiation intensities, monitor the effectiveness of shielding arrangements, and estimate exposure to personnel.There are two main categories of radiation monitoring devices: gas filled detectors and scintillation detectors.he kind of detector used is based on the intensity and the type of radiation field encountered. Scintillation detectors operate on the principle that certain materials scintillate or give off light when exposed to radiation. There are two major types of scintillation detectors, crystal and liquid.
