THE ELECTRICAL SAFETY OF INSTRUMENTS USED FOR THE MEASUREMENT OF REFRIGERATED HYDROCARBONS

The electrical safety of instruments used for the measurement of refrigerated hydrocarbons during processing or in storage is discussed in relation to plant area classification based on the degree of hazard presented; various methods of safeguarding electrical apparatus, with emphasis on intrinsically safe systems; the successful use of shunt diode safety barriers to control the current between uncertified apparatus and certified apparatus in a hazardous area; a design method for intrinsically safe systems; the installation, inspection, and maintenance of electrical apparatus; instruments most commonly used for the measurement and control of refrigerated hydrocarbon liquids; and some problems encountered in practice with electrical instruments.
