Heat Dissipation

Alefe

Thermal Dissipation, expressed in watts per square centimeter (W/cm²), is one of the most important parameters when evaluating the performance and safety of a silicone heating blanket. This value indicates how much heat the blanket is capable of transferring to the heated surface per unit area, determining efficiency, heating time, and equipment durability. Silicone heating blankets are constructed with embedded electrical resistance elements between layers of silicone rubber — a material known for its excellent thermal resistance, flexibility, and electrical insulation properties. However, even though they are robust, they must…Continue readingHeat Dissipation

Pressure Conversion Guide

Alefe

There are several pressure units and scales used across industry, physics, meteorology, and engineering. Below are the main ones: 1. Pascal (Pa) – International System (SI) The Pascal is the official pressure unit of the International System of Units (SI). 1 Pa = 1 N/m² It is used in physics, scientific research, and precise calculations. 2. Bar and mbar (bar / millibar) Widely used in industry and technical applications. 1 bar = 100,000 Pa1 mbar = 0.001 bar Millibar is commonly used in meteorology. 3. Atmosphere (atm) Represents the average…Continue readingPressure Conversion Guide

Requirements for Proper Heater Sizing

Alefe

Most difficulties encountered in electric heating systems can be quickly resolved when the correct amount of heat required for the process is properly determined. To achieve this, the required heat must be converted into electrical power (kW), allowing the selection of the most appropriate heater. Whether heating solids, liquids, or gases, the calculation logic remains essentially the same. All heating projects involve the following steps: Definition of the Heating Problem • Gather all relevant application data.• Prepare a sketch or schematic to facilitate visualization of the situation. Power Requirement Calculation…Continue readingRequirements for Proper Heater Sizing

Types of Temperature Sensors

Alefe

Types of Temperature Sensors Temperature measurement is essential in industrial processes, laboratories, and electronic applications. For this purpose, a variety of sensors are used, each with specific characteristics regarding accuracy, temperature range, stability, and cost. Among the most common are Type J and Type K thermocouples, PT100 and NI120 resistance sensors, and PTC sensors. 1. Type J Thermocouple The Type J thermocouple is composed of two metals: iron (Fe) and constantan (Cu-Ni). Typical range: –40°C to 750°CAdvantages: low cost, fast response, and suitable for dry, non-oxidizing environments.Disadvantages: iron oxidizes easily,…Continue readingTypes of Temperature Sensors

Theoretical Fundamentals of Heat Transfer”

Alefe

Heat transfer is the process by which heat moves from one body to another due to a temperature difference. In physical terms, heat always flows spontaneously from the hotter body to the cooler one until both reach thermal equilibrium. Heating energy is basically transferred through three modes, and most heating applications involve one or another method described below: Conduction is the mechanism of heat transfer in which thermal energy is transmitted from one point to another through the interaction of atoms or molecules of matter. Generally, energy transfer occurs through…Continue readingTheoretical Fundamentals of Heat Transfer”

Ohm’s Law

Alefe

Ohm’s Law is one of the fundamental principles of electricity. Formulated by the German physicist Georg Simon Ohm, it describes the relationship between voltage, electric current, and resistance in an electrical circuit. Simply put, the law states that: The electric current flowing through a conductor is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. This relationship is expressed by the formula: V = R · I Where: How to understand this? Practical applications of Ohm’s LawOhm’s Law is present in almost everything involving…Continue readingOhm’s Law
