Thermocouples

At Elmatic, we manufacture a wide range of high-quality industrial thermocouples and temperature sensors, all designed to meet demanding process requirements across diverse applications. Our sensors are available in Mineral Insulated (MI) formats as well as Platinum Resistance Thermometers (RTDs – PT100), with numerous styles, diameters, and terminations to suit your exact specifications.

Mineral Insulated Thermocouples

Our mineral insulated thermocouples are engineered for exceptional durability and performance in harsh operating conditions. These highly robust sensors are suitable for temperatures ranging from –200°C to +1250°C, depending on the thermocouple type and sheath material.

Key Features

• Extremely rugged and vibration-resistant
• Suitable for dynamic or harsh industrial environments
• Sheaths can be bent, twisted, or flattened without compromising performance
• Excellent thermal response and long service life
• Available with a wide range of terminations and probe configurations

For standard types, please refer to our Thermocouple Colour Code Chart.

Available Thermocouple Types

We manufacture a broad selection of popular industrial thermocouple types, including:

• Type K (Nickel-Chromium / Nickel-Alumel)
• Type J (Iron / Constantan)
• PT100 Platinum Resistance Thermometers (RTDs)

Available Sheath Diameters

Thermocouple probes can be supplied in a wide range of diameters, including:

• 0.25 mm
• 3 mm
• 4 mm
• 4.5 mm (3/16″)
• 5 mm
• 6 mm (1/4″)
• 8 mm

These options allow precise matching to response time, flexibility, and strength requirements for your application.
