Thermocouples & RTD's
Thermocouple & RTDs PT100 in Pakistan
A thermocouple is a type of temperature sensor that is commonly used in industrial settings. It consists of two different metal wires that are connected at one end. When a temperature difference occurs between the two ends of the wires, a small electrical voltage is generated. This voltage can then be measured and used to determine the temperature of the surrounding environment.
RTDs (Resistance Temperature Detectors), like PT100, are another type of temperature sensor that are commonly used in industrial settings. Unlike thermocouples, which rely on the thermoelectric effect to generate a voltage, RTDs use the change in electrical resistance of a material as the temperature changes. PT100 is a type of RTD that is made of platinum and has a resistance of 100 ohms at 0 degrees Celsius.
Hi-Tech is the manufacturer of both thermocouples and RTDs in Pakistan that are widely used for temperature measurement and control in various industrial applications such as power plants, petrochemical plants, and food processing plants. We produce various types and sizes, which makes it easier for Pakistani industries to access these devices at a reasonable cost.
