How Temperature Controls & Sensors Work Inside Electric Burners – The Complete Guide

Introduction: Why is burner temperature control important?

When you are cooking, burner temperature control is essential. If the correct temperature is not maintained, food can burn or may not cook properly. Electric burners use various sensors and technologies to control temperature. In this article, we will discuss in detail how these sensors work, their differences, and how they improve your cooking experience.

Main Parts of an Electric Burner

An electric burner mainly consists of a few important parts:

• Heating Element: It generates heat through the flow of electricity. Usually made of nickel-chromium alloy, this element can withstand high temperatures.
• Thermostat: It controls the burner’s temperature. When the temperature exceeds the specified limit, the thermostat stops the flow of electricity.
• Temperature Sensor: It measures the actual temperature and sends a control signal to the thermostat.
• Control Panel: The user uses this panel to set the temperature. It receives information from the sensor and controls the heating element.
• Circuit Breaker: Prevents excessive current flow to avoid damaging the burner.

Types of temperature sensors and their working methods

Different types of sensors are used in electric burners. Each sensor has its own characteristics and procedures.

1. Thermocouple Sensor

How it works: A thermocouple sensor is made of two different metals. When these wires heat up, they generate an electric voltage. This voltage informs the thermostat about the burner’s temperature.

Features:

• Can detect rapid temperature changes.
• Often used with burner pilot lights.
• Temperature range: -200°C to 1300°C.

2. Thermistor Sensor

How it works: A thermistor is a temperature-sensitive resistor. Its resistance changes with temperature variations. This change provides temperature information to the thermostat.

Features:

• Can measure very precise temperatures.
• Commonly used in induction burners.
• Temperature range: -50°C to 300°C.

3. RTD Sensor (Resistance Temperature Detector)

How it works: RTD sensors are made of platinum, nickel, or copper wire. As the temperature changes, so does its resistance. This change informs the thermostat about the temperature.

Features:

• Can measure temperatures very accurately.
• Typically used in high-end induction burners.
• Temperature range: -200°C to 850°C.

Temperature Control Process

The process of temperature control in electric burners involves several steps:

Step 1: User Input

The user sets the burner temperature through the control panel. For example, they can select the “Medium” or “High” setting.

Step 2: Temperature measurement by sensor

The sensor inside the burner measures the actual temperature. For example, the thermocouple sensor measures the burner’s temperature and generates an electrical signal.

Step 3: Control via thermostat

The thermostat analyzes the signal received from the sensor. If the temperature exceeds a user-set limit, the thermostat shuts off the power flow. Otherwise, it keeps the current flowing.

Step 4: Heat is generated by the heating element

According to the thermostat’s control, the heating element generates heat through the flow of electricity. This heat is then transferred to the pot placed on the burner.

Step 5: Continuous monitoring

The burner continuously monitors the temperature. If the temperature drops below a specific range, the thermostat turns the power flow back on. This process keeps the burner at the user’s desired temperature.
