This article covers the common Instrumentation Abbreviations, Instrumentation Definitions, Instrumentation Symbols, Nomenclature, and Acronyms.

2013年9月16日 · This document provides a list of common abbreviations used for instruments in oil and gas applications. It is adapted from the ISA Standard S5.1 and organized alphabetically from A to Z. The abbreviations cover a wide range of process variables and instruments including pressure, level, flow, temperature, alarms, switches, controllers and more.

2010年10月27日 · Similar to equipment and instrumentation, every pipe on a P&ID requires a unique tag number so that it can be uniquely identified during design, or referenced in operating procedures.

We Provide Tools and Basic Information for Learning Process Instrumentation and Control Engineering. To further understand instrument abbreviations used in instrumentation and process diagrams, we have presented more examples of the common combinations of instrument abbreviations you may likely come across.

Abbreviated as P&ID, a piping and instrumentation diagram is an articulate drawing of a processing plan that entails the piping and process equipment with its instrumentation and control machinery. It displays the piping and associated parts of a physical process flow. Such diagrams are famous in the engineering field.

Nanobodies (VHH) possess the same domains as traditional antibody VH, which includes four conserved framework regions (FR1/2/3/4) and three complementarity-determining regions (CDR1/2/3) (Fig. 2). There are four highly conserved hydrophobic amino acid residues (V42, G49, L50, and W52) of FR2 in VH of the conventional antibodies.

根据受力分析，可以得知，液体柱的压强不受两侧的影响，所以液体柱的压强是满足p=ρgh的关系的，那么液体柱对左侧楔形整个的压力P1就是 \int_ {0}^ {h}\rho g h=0.5\times \rho g h^ {2} ，那么，自然可以得到N=P1÷cosβ=0.5×ρgh^2/cosβ，所以N1=m1g+Nsinβ=m1g+0.5×ρgh^2×tanβ=m1g+0.5 ...
