Insert MI Thermocouple for Thermowell is a high-performance temperature sensing solution designed for use with new or existing heavy-duty thermowells in demanding industrial applications. These spring-loaded, mineral insulated thermocouple inserts are engineered to provide accurate and reliable temperature measurement while ensuring fast response times and long-term durability.
The sensor is typically supplied with a 6.0 mm outer sheath diameter, with additional options including 3.0 mm, 4.5 mm, and 8.0 mm to suit specific installation requirements. The spring-loaded design keeps the sensing tip firmly in contact with the bottom of the thermowell, improving heat transfer and ensuring faster, more accurate temperature readings.
Each MI thermocouple is manufactured using high-quality mineral insulated thermocouple technology, offering excellent resistance to vibration, pressure, and high temperatures. A ceramic terminal block is supplied as standard for secure connection within a terminal head, while an optional 4-20 mA transmitter can be integrated for advanced process control applications.
As a trusted mineral insulated thermocouple exporter, we provide customized solutions for various industrial processes. Whether you need to buy mineral insulated thermocouple inserts for replacement or new installations, our products deliver reliable performance and measurement accuracy.
