Design of embedded fuel sensor based on intrinsically-safe circuit
2017 Chinese Automation Congress (CAC), 2017The accurate measurement of fuel level plays a significant role in the cruise time and safety performance of aircraft. Capacitive sensors are currently used to measure fuel level in many aircrafts. In order to reduce the wall destruction of fuel tank and solve the problem of intrinsically safety, researchers introduce a new capacitive sensor, based on ...

Study on Non-Explosive Assessing System for Intrinsically Safe Circuit
2009 International Conference on Information Engineering and Computer Science, 2009Due to the advantages of the intrinsically safe circuit, people are increasingly willing to make use of it in comprehensive automatization system and communication equipment. If practical non-explosive testing methods can be constructed base on discharge theory of intrinsically safe circuit, the designers will find it easier to grasp the performance of

Lightning and surge protection in intrinsically safe measuring circuits
R. STAHL Ex Magazine, 2021Processing or transporting combustible substances can often lead to the creation of mixtures capable of forming an explosive atmosphere. Strict safety precautions must be in place when setting up and operating systems in which substances of this kind may be present. This is also set out in Directive 1999/92/EC [1], which addresses the user or employer.

Energy and Power Criterion of Intrinsically Safe Circuits for Explosive Atmospheres
2011Arc discharge time(T) is determined to be in proportion to time constant(1) based on current linear attenuation model for intrinsically safe inductive circuits. It draws conclusions that maximum value of arc power(Pmax) is in proportion to arc energy(Wg) and is inverse to time constant (1).The conflicting fact that greater sparks can not cause gas ...
