Thermocouple alloy and junction selection
Thermocouple Head: Match thermocouple type, polarity and extension cable to the controller input. Select protection-tube material and grounded or ungrounded junction for the atmosphere, electrical noise and response required.
Define insertion depth and the mechanical support at the process connection. A temperature stated in a product name needs confirmation for the complete probe assembly, cable transition and continuous duty.
The archived configuration for Thermocouple Head lists Field-Mountable: Allows on-site assembly for custom thermocouple installations.; DIN Rail Mount: Designed to attach to DIN rails in control panels.. Treat these as reference options and reconcile them with the named configuration and installation drawing before quotation.
For Thermocouple Head, send the controller input, required measurement range, accuracy, probe drawing and cable or connector details. Ask for the agreed sensor designation and inspection requirements on the quotation.
Application and reference configuration
Industrial temperature monitoring and furnace control. The final suitability of Thermocouple Head depends on the assembled equipment and agreed operating conditions.
Archived figures below describe reference options or a product series. Confirm the exact model specification in the quotation.

ARCHIVED PRODUCT INFORMATION
Description
A thermocouple head (also called a thermocouple connection head or terminal head) is a protective enclosure that houses the electrical connections between a thermocouple sensor and its extension or instrumentation cable. It ensures secure, stable, and sometimes watertight connections while shielding the wiring from environmental damage.
Key Features of a Thermocouple Head:
Material
Typically made of aluminum, stainless steel, or plastic (depending on temperature and corrosion resistance needs).
Explosion-proof versions are available for hazardous areas.
Terminal Block
Provides screw terminals or connectors for joining thermocouple wires to extension cables.
Must maintain proper polarity (positive/negative terminals).
Protection Rating
Common ratings: IP65 (dust-tight, water-resistant), IP67 (submersion-proof), or NEMA 4X (corrosion-resistant).
Mounting Options
Threaded (e.g., M16, 1/2" NPT) for direct attachment to thermocouple probes.
Flange-mounted for larger industrial sensors.
Temperature Limits
Plastic heads: Up to ~100°C.
Metal heads: Can withstand higher temps (e.g., 200°C+).

Wiring Inside a Thermocouple Head
Thermocouple wires must connect to matching extension cables (e.g., Type K to Type K).
Polarity matters: Positive (red) and negative (black/white) must match.
Avoid mixing metals (e.g., don't splice copper wire directly to a thermocouple).
Product Advantage
1:High temperature resistance, flexible, anti-corrosion, fast and accurate temperature measurement
2:High temperature resistant Extension wire
3:Probe length can be customized, probe can be bent
4:Arbitrary bending, high temperature resistance, long service life, fast response speed, fixed spring
5:High Precision Temperature control probe
6:Quick response,OEM Accepted
When the junction is exposed to a temperature difference, a voltage is generated across the junction, which can be measured and used to determine the temperature.
The K type thermocouple has a temperature range of approximately -200°C to 1350°C and is commonly used in furnaces, kilns, and other high-temperature applications.
One of the advantages of the K type thermocouple is its relatively low cost compared to other types of thermocouples.
It also has good accuracy and stability over a wide temperature range, making it a popular choice for many applications.
