- Durable construction for harsh environments
- Multiple sensors styles for furnaces, ovens, process lines, and OEM equipment
Best for:
- furnaces & kilns
- ovens
- heaters
- extruders
- hot runner systems
- process lines
Types of Thermocouple Sensors & Temperature Ranges
Different thermocouple types are selected based on operating temperature, atmosphere, accuracy needs, and application conditions (oxidizing/reducing environments).
1. Base Metal Thermocouples (Type J, K, T, E) These are the most common thermocouple sensors used in industrial automation. They offer a cost-effective solution for temperatures up to 1200°C.
- Type K (Chromel/Alumel):The industry standard for general high-temperature applications. As Type K thermocouple sensor manufacturers in Mumbai, we manufacture sensors for furnaces, HVAC systems, and industrial process heating applications.
- Type J (Iron/Constantan): Ideal for reducing atmospheres and vacuum applications. As J-type thermocouple manufacturers in Mumbai, we offer customised configurations for industrial temperature measurement.
- Type T (Copper/Constantan): Suitable for low-temperature applications requiring stable and accurate measurement. As T Type thermocouple manufacturers in Mumbai, we manufacture Type T sensors for refrigeration, food processing, and laboratory applications.
- Type E (Chromel/Constantan): Offers higher sensitivity than many other base metal thermocouples, making it suitable for lower-temperature industrial processes. As E Type thermocouple manufacturers in Mumbai, we provide customised Type E sensors for specialised industrial applications.
- Construction: Available in Mineral Insulated (MI) and tubular sheath designs to suit different installation and process requirements.
2. High Temperature Thermocouples (Noble Metal – Type R, S & B)
Designed for extreme heat, our high-temperature thermocouple range uses Platinum/Rhodium elements protected by high-purity Ceramic (Alumina) sheaths for stable performance in furnaces, kilns, and heat-treatment applications.
- Type R (Platinum/13% Rhodium-Platinum): Suitable for high-temperature industrial processes requiring excellent accuracy and long-term stability. As R-type thermocouple manufacturers in Mumbai, we supply sensors for furnaces, kilns, and heat-treatment equipment.
- Type S (Platinum/10% Rhodium-Platinum): Ideal for continuous high-temperature measurement where consistent performance is critical. As S-type thermocouple manufacturers in Mumbai, we manufacture sensors for glass, ceramic, and metallurgical industries.
- Type B (Platinum/30% Rhodium-Platinum): Designed for extremely high-temperature furnace applications with excellent durability at elevated temperatures. As B-type thermocouple manufacturers in Mumbai, we provide sensors for steel plants, foundries, and high-temperature process industries.
- RTD Thermocouple Assemblies – While technically distinct, many industries use the term “RTD thermocouple” to refer to high-precision temperature assemblies. As RTD thermocouple manufacturers in Mumbai, we manufacture hybrid assemblies that combine the accuracy of an RTD with the rugged protection head of a thermocouple for specialised process control applications.
Technical Comparison: Selecting the Right Thermocouple
Choosing the correct thermocouple sensor is critical for sensor longevity.
| Type | Category | Typical Range (°C) | Best For |
|---|---|---|---|
| K | Base metal | -200 to 1260 | General industrial, furnaces, ovens |
| J | Base metal | -40 to 750 | Lower temp industrial processes |
| T | Base metal | -200 to 350 | Low-temp, stable environments |
| N | Base metal | -200 to 1300 | High temp stability vs K (process) |
| R/S | Noble metal | 0 to 1600 | High temp, better stability |

Frequently asked questions (Thermocouple Sensors)
What is a thermocouple sensor?
A thermocouple is formed by joining two dissimilar metals; it generates a voltage proportional to temperature difference, which is converted into a temperature reading.
Which thermocouple type is best for high temperature?
For high temperature thermocouple applications, K and N are common base-metal types, while R/S/B are used for very high temperature furnace zones.
What is the difference between RTD and thermocouple?
Thermocouples are preferred for high temperatures and rugged environments; RTDs (PT100) are often chosen for higher accuracy and stability at moderate temperatures.
Which thermocouple type is best for 1200°C?
For 1200°C, a Type K thermocouple is a cost-effective choice, but for continuous operation or higher accuracy, a Type R or S high temperature thermocouple is recommended.
What details are needed to order thermocouple sensors?
Temperature range, thermocouple type, junction type, sensor length, mounting thread/flange/bayonet details, cable length, and termination type.
What is the J Type thermocouple price in India?
The J-type thermocouple price in India depends on factors such as sensor length, sheath material, diameter, process connection, and cable configuration. Contact us with your specifications for an accurate quotation.
What is the difference between grounded and ungrounded thermocouples?
Grounded thermocouples provide faster response because the sensing junction is connected to the sheath, while ungrounded thermocouples offer better electrical isolation in applications where interference is a concern.
What junction types are available?
We manufacture thermocouples with grounded, ungrounded, and exposed junctions, depending on the required response time, electrical isolation, and application.
