Aichelin Unitherm Heat Treatment Systems India Interview Questions and Answers

Resistance is the opposition to the flow of electric current through a conductor.

• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in the conductor.

• Resistance converts electrical energy into heat.

• Higher resistance leads to lower current flow.

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

The faulty finding procedure for motor failure involves a systematic approach to identify and diagnose the cause of the failure.

• Start by gathering information about the motor failure, such as symptoms, error codes, and any recent changes or incidents.

• Perform visual inspections to check for any obvious signs of damage or malfunction, such as burnt components or loose connections.

• Conduct electrical tests to measure volta...read more

A temperature controller is a device used to regulate and maintain a desired temperature in a system or process.

• It measures the temperature using a sensor.

• It compares the measured temperature to a setpoint or desired temperature.

• Based on the comparison, it activates or deactivates a heating or cooling element to adjust the temperature.

• It ensures that the temperature remains within a specified range.

• Temperature controll...read more

A PID controller is a feedback control loop mechanism widely used in engineering to control systems and processes.

• PID stands for Proportional-Integral-Derivative.

• It continuously calculates an error value as the difference between a desired setpoint and a measured process variable.

• The controller then adjusts the control signal to minimize the error and bring the process variable closer to the setpoint.

• The proportional t...read more

Yes, I have a basic understanding of PLC (Programmable Logic Controller).

• PLC is a digital computer used for automation of electromechanical processes.

• It uses a programmable memory to store instructions and execute them in real-time.

• PLCs are commonly used in industrial settings to control machinery and processes.

• They can be programmed using ladder logic, function block diagrams, or structured text.

• PLCs can interface wit...read more

The formula for resistance is R = V/I, where R is resistance, V is voltage, and I is current.

• Resistance is the measure of opposition to the flow of electric current.

• The unit of resistance is ohm (Ω).

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

• For example, if the voltage across a resistor is 10 volts and the current passing through it is 2 amps, the resist...read more

Should costing is a process of estimating the manufacturing cost of a product based on its design, materials, and manufacturing processes.

• Should costing involves analyzing the design, materials, and manufacturing processes to determine the cost of producing a product.

• It helps in identifying cost-saving opportunities by comparing the estimated cost with the actual cost.

• Should costing can be used to negotiate better pric...read more

A zero watt bulb is a bulb that consumes zero watts of power when turned on.

• A zero watt bulb typically refers to an LED bulb that consumes very low power, close to zero watts, when turned on.

• These bulbs are energy efficient and have a very low power consumption compared to traditional incandescent bulbs.

• Zero watt bulbs are often used in applications where minimal power consumption is desired, such as night lights or in...read more
