Roll responsible in your previous company. What is ISO certification? What is Hazardous classification, Describe Briefly. Characteristics of zener barrier and avalanche breakdown ? How to select instruments? Difference between PLC & DCS? Working principle of magnetic flow meter & Mass flow meter?

Question

Accepted Answer

ISO certification is a quality management system that ensures a company meets international standards. Hazardous classification categorizes materials based on their potential risks. Zener barrier and avalanche breakdown are characteristics of electronic components. Instruments are selected based on factors like accuracy and reliability. PLC and DCS are both control systems used in industrial automation. Magnetic flow meters measure flow based on Faraday's law of electromagnetic induction, while mass flow meters measure flow based on the mass of a substance.

ISO certification ensures a company meets international quality standards.
Hazardous classification categorizes materials based on their potential risks, such as flammability or toxicity.
Zener barrier is a type of electronic component that regulates voltage, while avalanche breakdown is a phenomenon where a semiconductor device breaks down due to high voltage.
Instruments are selected based on factors like accuracy, reliability, cost, and compatibility with the application.
PLC (Programmable Logic Controller) is typically used for discrete control applications, while DCS (Distributed Control System) is used for continuous control processes.
Magnetic flow meters measure flow by inducing a voltage in a conductive fluid, while mass flow meters measure flow by measuring the mass of a substance passing through a sensor.
