XC

Supported Applications

The Omega XC Series consists of Nextel®-covered flexible thermocouple elements designed for high-temperature applications. These ceramic-insulated sensors feature a flexible design intended for hard-to-reach locations and are compatible with OMEGA® ceramic protection tubes and wells.

Operating Conditions & Performance

The series supports continuous use up to 1200°C (2200°F) or short-term exposure up to 1425°C (2600°F). Accuracy meets or exceeds Special Limits of Error (SLE) of ANSI MC96.1-1982 and EN 60584-2, Tolerance Class 1. Temperature limitations are determined by the type of thermocouple material selected.

Measurement Ranges

The available temperature ranges vary by thermocouple type and AWG size:

• Type K: 0 to 1090°C (32 to 2000°F) for 14 AWG; 0 to 980°C (32 to 1800°F) for 20 and 24 AWG
• Type J: 0 to 590°C (32 to 1100°F) for 14 AWG; 0 to 480°C (32 to 900°F) for 20 AWG; 0 to 370°C (32 to 700°F) for 24 AWG
• Type E: 0 to 650°C (32 to 1200°F) for 14 AWG; 0 to 540°C (32 to 1000°F) for 20 AWG; 0 to 430°C (32 to 800°F) for 24 AWG
• Type N: 0 to 1090°C (32 to 2000°F) for 14 AWG; 0 to 980°C (32 to 1800°F) for 20 and 24 AWG

Configuration Options

The XC Series is configurable across multiple dimensions including thermocouple type, wire gauge, length, insulation material, and connector options.

Sensor Elements & Insulation

• Thermocouple Types: K, J, E, N
• American Wire Gauge (AWG): 14, 20, 24
• Insulation Material: Nextel® ceramic fiber insulation is standard. Silica insulation is available by changing the series prefix from 'XC' to 'XS' with no additional cost.
• Overbraiding: Stainless steel or Inconel® overbraiding for abrasion protection (consult Sales).

Dimensions & Termination

• Standard Length: 300 mm (12"). Other lengths are available; to order longer elements, change the '12' in the model number to indicate the actual length required.
• Termination: 13 mm (0.5") stripped end termination with color-coded leads.

Connector Options

Add the following codes to the model number for additional cost:

• M8-S-M: Male straight M8 plug
• M12-S-M: Male straight M12 plug (listed as 'M12-S-M' in options; note that right-angled 12mm is also listed as 'M12-S-M' in the source text)
• M8-R-M: Male right-angled M8 plug
• Male right-angled M12 plug (add to model number for additional cost)

Assembly Integration

OMEGA can combine these elements with thermowells and industrial heads to produce a complete head and well assembly, available for fast delivery.

Key Product Differences

The primary variation within the series is defined by the model number format: XC-<AWG>-<Type>-12 (example: XC-20-J-12). The 'XC' prefix denotes Nextel® ceramic fiber insulation, while changing this to 'XS' specifies silica insulation. Specific lengths are indicated in inches at the end of the part number.
