Thermocouples

High-Performance Head-Type Thermocouples

At Reinmeer, we engineer robust head-type thermocouples designed to deliver precise temperature measurements even in the most demanding industrial environments. Featuring a heavy-duty connection head, our sensors protect the terminal block and internal wiring from moisture, dust, and corrosive elements, ensuring long-term stability, safety, and uninterrupted performance.

1. Robust Construction & Components

Our head-type thermocouples are designed with modularity and durability in mind.

The core construction features several key components to ensure reliable measurement and easy maintenance:

• Connection head B type

• Process connection for secure mounting

• Protection tube to shield the internal sensor

• Temperature Transmitter (Sıcaklık Transmitteri) integration directly within the head

• Reduced tip of protection tube (Ø D / Ø D1 mm) for faster thermal response times

• Measuring insert ( L2), which can be easily replaced without removing the entire assembly

2. Measuring Junction Types

The measuring hot junction is the point where the thermoelectric wires are joined together. This section constitutes the actual temperature sensor, which can be manufactured in various configurations. The outer sheath is sealed by welding, and the weld seam is meticulously inspected to ensure leak-tightness.

Depending on your process requirements, we offer two main junction configurations, both insulated with Magnesium oxide (MgO) within a metal sheath:

• Ungrounded Thermocouple (Type I): The hot junction is isolated from the metal sheath. This provides excellent electrical insulation and prevents ground loops.

• Grounded Thermocouple (Type G): The hot junction is welded directly to the inside of the metal sheath. This offers a faster response time to temperature changes.

3. Connection Head & Cable Gland Options

To accommodate different environmental conditions and cabling requirements, we provide a variety of cable gland and connection head options:

• KMC: Aluminum Cast Head

• BUZ-W: Aluminum Head

• KD: Aluminum Head

• XD: Aluminum Cast Head

4. Electrical Connection of Terminal Blocks

Proper wiring is critical for accurate signal transmission. Our terminal blocks are clearly marked for safe and correct installations.

We support multiple sensor configurations to meet your specific monitoring needs:

• Single Thermocouple: Standard configuration with explicitly marked positive (+) and negative (-) terminals.

• Double Thermocouple: Two independent measuring circuits within a single unit.

• Triple Thermocouple: Three independent measuring circuits for advanced multi-point monitoring.

5. Mounting Methods

Proper installation is essential for accurate temperature reading and sensor longevity. Our thermocouples support various pipeline installation configurations to suit your process geometry:

• Pipeline installation 90°: Standard perpendicular mounting for optimal immersion in standard pipes.

• Pipeline installation 45°: Angled mounting, ideal for smaller pipe diameters to increase the immersion length of the sensor tip into the fluid medium.

• Versatile mounting solutions adapt to different pipe layouts and orientations.
