Thermocouple with IP67 heavy duty cast iron head
Mineral Insulated Thermocouples
- Mineral insulated thermocouple sensors have a high integrity construction, suited to arduous operating conditions at temperatures from -200ºC to +1400ºC. (The maximum operating temperature is dependant on diameter and environmental factors, further guidance is available here.)
- Custom built to your specification and terminated in a weatherproof cast iron screw top terminal head with the tube entry and cable entry at a right angle to each other. Suitable for simplex, duplex and triplex assemblies. Supplied complete with 20mm x 1.5mm ISO metal pinch gland on cable entry for cables from 6mm to 14mm diameter
- Alternatively, we have a large range of sensors available to buy online in various diameters and lengths
- High accuracy and stability maintained throughout the operating life of the sensor
- Fast response and high insulation resistance
- Available in thermocouple types K, T, J, N, E, R, S & B with sheath diameters from 4.5mm to 8.0mm and lengths from a few millimetres to 200 metres or more dependent on the sheath diameter selected
Frequently Asked Questions
- What is a thermocouple and how does it work?
A thermocouple is a type of temperature sensor that generates a voltage when two different metals are joined at one end and exposed to a temperature difference between the "hot" junction (where the temperature is measured) and the "cold" junction (the reference point). This voltage is then measured to determine the temperature at the hot junction.
- How do I choose the right thermocouple for my application?
The ideal thermocouple depends on factors such as temperature range, accuracy, termination type, mounting requirements and environmental conditions. We offer a variety of thermocouples with different sheath materials, constructions, terminations, and temperature ratings to meet your needs. If you need specific advice, our engineers are happy to assist!
- What is the maximum temperature rating of your thermocouples?
Our thermocouples are designed to handle a wide range of temperatures with some mineral insulated thermocouples able to withstand temperatures up to 1400ºC and ceramic sheathed thermocouples going even higher to 1600ºC. Each product listing includes the maximum temperature rating, so you can choose the best thermocouple for your application.
