Leading Thermistor Manufacturer Company in India

Thermistors are semiconductors that react like resistors in response to temperature, which means they have more resistance than conducting materials but less resistance than insulating materials. To establish a temperature measurement, the measured value of a thermistor’s electrical resistance can be associated with the temperature of the environment in which the thermistor is located.

Thermistors are still used for monitoring temperature because of their more considerable resistance change per degree of temperature, which provides better resolution. – High degree of reproducibility and stability.

Top 10 Companies of Thermistor Manufacturers in India

Arcotherm Private Limited

Arcotherm is a Thermistor manufacturer of various types of thermistors. It is an expert in NTC thermistors used as resistance thermometers in low-temperature ( – 40 to + 123 degrees ) measurements. NTC thermistors can be used as inrush-current limiting devices in power supply circuits. They present a higher resistance initially, which prevents large currents from flowing at turn-on. Then, they heat up and become much lower resistance, allowing higher current flow during regular operation. These thermistors are usually much more significant than measuring-type thermistors and are purposely designed for this application.

Thermosen Technologies

Many NTC thermistors are made from a pressed disc, rod, plate, bead or cast chip of semiconducting material such as sintered metal oxides. Thermosen NTC thermistors are famous for their consistent and reliable output; we have the experience and capability to design custom NTC thermistors beside our regular range. A thermistor is a type of resistor whose resistance depends on temperature; in NTC (Negative Temperature Coefficient) thermistors, resistance decreases as temperature rises. An NTC is commonly used as a temperature sensor or in series with a circuit as an inrush current limiter.

Source Technologi

Building electronic components from the core, some of their products include- chip resistors, thermistors, ICs, diodes, film capacitors, chip ceramic capacitors array, chip ceramic capacitors, etc.

Application of Thermistor Manufacturers

Thermistors, which are temperature-sensitive resistors, find numerous applications across various industries due to their ability to sense and respond to changes in temperature accurately. Some typical applications of thermistors include:

Temperature Measurement and Control: Thermistors are widely used for temperature sensing in various electronic devices, such as thermostats, HVAC systems, ovens, refrigerators, and water heaters. They provide precise temperature measurements and help control heating or cooling systems to maintain desired temperatures.

Overcurrent Protection: Thermistors can be used as temperature-sensitive fuses to protect electronic circuits from overcurrent conditions. When the current exceeds a certain threshold, the thermistor’s resistance increases sharply, limiting the current flow and protecting the circuit components.

Medical Devices: In medical equipment and devices like thermometers, incubators, and blood analyzers, thermistors are used for accurate temperature monitoring and control. They ensure the safety and effectiveness of medical procedures by maintaining stable temperatures.

Automotive Applications: Thermistors are employed in automotive systems for temperature monitoring and control in various components such as engine coolant systems, HVAC systems, and battery management systems. They help optimize engine performance, prevent overheating, and ensure efficient operation of vehicle systems.

Industrial Process Control: Thermistors are utilized in industrial applications to monitor and control temperature in processes like plastic moulding, food processing, chemical manufacturing, and HVAC systems in buildings. They ensure consistent product quality, process efficiency, and safety.

Environmental Monitoring: Thermistors are used in environmental monitoring systems to measure temperature in weather stations, greenhouses, and climate-controlled environments. They help researchers and environmentalists collect climate studies, agriculture, and ecology data.

Consumer Electronics: Thermistors are integrated into various consumer electronics, including laptops, smartphones, and digital cameras, for temperature monitoring and thermal management. They help prevent overheating and ensure the reliable operation of electronic devices.

Energy Management: Thermistors play a role in energy management systems by monitoring temperature in appliances and equipment, optimizing energy usage, and improving energy efficiency. They contribute to reducing energy consumption and operating costs in residential, commercial, and industrial settings.

Fire Detection and Prevention: Fire alarm systems utilize thermistors to detect abnormal temperature increases and trigger alarms. They help in the early detection of fire hazards, enabling prompt action to prevent property damage and ensure safety.

Refrigeration and Air Conditioning: Thermistors are integral to refrigeration and air conditioning systems for temperature control and monitoring in compressors, evaporators, and thermostats. They help maintain optimal cooling conditions and energy efficiency in refrigeration and HVAC applications.
