Product 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+).
-
Types of Thermocouple Heads
| Type | Description |
|---|---|
| Standard Head | Basic enclosure for general-purpose use (e.g., labs, HVAC). |
| Explosion-Proof | Certified for hazardous areas (e.g., petrochemical plants). |
| Field-Mountable | Allows on-site assembly for custom thermocouple installations. |
| DIN Rail Mount | Designed to attach to DIN rails in control panels. |
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).
