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.
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+).
| 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. |
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).
