Instrument Pig Video Tutorial: Calculation Series – Lecture 1: Calculation of Intrinsic Safety Circuits

Thread Content

The *Instrument Pig Video Learning Course – Calculation Section* covers topics such as verification of the compatibility of current-loop parameters, calculation of resonance in thermometer protective sleeves, determination of the safety integrity level of circuits, calculation of the diameter of pipeline-type flow meters (vortex flow, electromagnetic, mass flow, etc.), calculation of the differential pressure for differential-pressure flow meters, calculation of the diameter of control valves, estimation of the number of control system cabinets, heat dissipation requirements, UPS load requirements, calculation of electromagnetic interference, and various calculations related to instrument piping and wiring. Lecture 1 of the Calculation Series: The video address for calculations related to intrinsically safe circuits is: http://v.qq.com/x/page/r03182zqwoe.html. Through this series of courses, we will learn together and discuss the calculation issues involved in instrument engineering design. Preview of the next lecture: Calculation of the resonance frequency of thermometer protective sleeves. Feel free to follow the WeChat official account of Instrument Pig to discuss this topic together.
