SAEL Industries Limited Interview Questions, Process, and Tips

Bearings and couplings are essential components in mechanical systems.

• Types of bearings: ball bearings, roller bearings, plain bearings, magnetic bearings, fluid bearings

• Types of couplings: rigid couplings, flexible couplings, fluid couplings, magnetic couplings

• Bearings support rotating shafts and reduce friction, while couplings connect two shafts together

• Examples of bearings and couplings used in mechanical systems: ...read more

Chain conveyors use chains to move products, while belt conveyors use belts.

• Chain conveyors are more durable and can handle heavier loads than belt conveyors.

• Belt conveyors are better suited for transporting smaller items and have a smoother operation.

• Chain conveyors are commonly used in industries such as automotive and steel, while belt conveyors are used in industries such as food processing and packaging.

• Chain conv...read more

RTD measures temperature using resistance while TC measures using voltage.

• RTD stands for Resistance Temperature Detector while TC stands for Thermocouple.

• RTD measures temperature by detecting the change in resistance of a metal wire while TC measures temperature by detecting the voltage generated by two different metals.

• RTD is more accurate and stable than TC but is also more expensive.

• TC can measure a wider range of t...read more

DCS and PLC are control systems used in industrial automation. Currently, we are using DCS.

• DCS stands for Distributed Control System and is used for large-scale industrial processes.

• PLC stands for Programmable Logic Controller and is used for smaller, discrete processes.

• DCS allows for centralized control and monitoring of multiple processes, while PLC is more suited for standalone machines.

• Our company uses DCS for our ...read more
