Description
Spring Loaded Bayonet Thermocouple (Model AKES-6×40) is a K-Type temperature sensor designed for reliable temperature measurement in industrial heating equipment, kilns, furnaces, ovens, and heavy-duty process applications. It features a 40 mm insertion length, making it suitable for installations where shallow mounting depths are required while maintaining dependable thermal contact.
The sensor uses a rotating 1-pin bayonet mounting system with a spring-loaded mechanism that continuously presses the sensing tip against the bottom of the mounting hole. This design helps maintain stable thermal contact despite vibration, thermal expansion, or repeated heating and cooling cycles, improving measurement consistency.
Manufactured with an SS316 stainless steel sheath, the thermocouple provides durability and corrosion resistance in demanding industrial environments. The K-Type sensing element measures temperatures from 0°C to 400°C, while the FG/FG/SS (Fiberglass insulated with Stainless Steel braided) cable offers protection against heat, abrasion, and mechanical wear. The standard 3-meter cable simplifies installation where the control panel or junction box is located farther from the sensing point.
The Spring Loaded Bayonet Thermocouple is widely used on industrial kilns, furnaces, ovens, diesel engine exhaust systems, gas turbine equipment, and heavy industrial heating processes, where dependable temperature monitoring supports efficient and safe operation.
Key Features
-
Compact 40mm Probe Tip Shortest tip design in the rotating bayonet range, tailored for shallow immersion depths and tight machine housings.
-
Extended 3-Meter Armored Cable Supplied with a longer 3m wire harness (compared to standard 2m leads) to span greater distances to remote control panels and transmitters.

FAQs
1. What is a Spring Loaded Bayonet Thermocouple?
A Spring Loaded Bayonet Thermocouple is an industrial temperature sensor that uses a spring-loaded bayonet mechanism to maintain continuous contact between the sensing tip and the measurement surface. This design helps provide accurate, stable, and repeatable temperature measurements in demanding industrial applications.
2. Why is a Spring-Loaded Design important?
The spring-loaded design compensates for vibration, thermal expansion, and minor dimensional changes during operation. By maintaining consistent pressure on the sensing tip, it ensures reliable thermal contact, improves measurement accuracy, and enhances long-term sensor performance.
3. What is the advantage of a Rotating Bayonet Mount?
A rotating bayonet mount enables quick installation and removal while allowing the cable to be positioned in the desired direction without twisting. This simplifies maintenance, improves cable routing, reduces mechanical stress on the cable, and helps extend the sensor’s service life.
4. Where are Spring Loaded Bayonet Thermocouples commonly used?
Spring Loaded Bayonet Thermocouples are widely used in industrial kilns, furnaces, ovens, heat treatment equipment, plastic processing machinery, gas turbines, diesel engine exhaust monitoring systems, packaging equipment, and industrial heating applications where reliable temperature measurement and secure sensor positioning are essential.
