IRCO-CHAL-P13R-P10R

Supported Applications

The Omega Fine Gage Bare Wire Thermocouple Elements series provides unsheathed temperature sensing elements for precision measurement. The product line encompasses base metal calibrations (Types J, K, T, E, and N) as well as platinum/rhodium noble-metal types (R, S, and B). These bare wire sensors are supplied in standard lengths suitable for integration into custom assemblies or direct insertion where fine gage dimensions are required.

Operating Conditions & Performance

The series supports a wide range of wire diameters from 0.025 mm (0.001") to 0.81 mm (0.032"). Standard lengths differ by calibration family: base metal thermocouples are offered in standard packages with a length of 300 mm (12"), while Pt/Rh calibrations have a standard length of 150 mm (6"). Base metal thermocouples with wire diameters of 0.125 mm (0.005") and larger are manufactured using Special Limits of Error wire.

Configuration Options

The series is configurable across multiple calibrations, wire sizes, and packaging options to meet specific assembly needs.

• Base Metal Calibrations: Available in Types J (Iron-Constantan), T (Copper-Constantan), N (OMEGA-P®/OMEGA-N®), K (CHROMEGA®/ALOMEGA®), and E (CHROMEGA®/Constantan). These are offered in convenient packages of five.
• Pt/Rh Calibrations: Includes Type R (Pt/13%Rh-Pt), Type S (Pt/10%Rh-Pt), and Type B (Pt/30%Rh-Pt/6%Rh). These are sold individually rather than in packages.
• Wire Diameters: Options range from 0.025 mm (0.001") up to 0.81 mm (0.032"). Specific diameters available include 0.050, 0.075, 0.125, 0.20, 0.25, 0.38, and 0.50 mm.
• Customization: Other sizes and lengths are available on special order. Orders for special sizes, alloys, or assemblies should be explicit and accompanied by a sketch or print if possible.

Key Product Differences

The primary distinction within the series is between base metal and noble-metal thermocouples regarding packaging and standard length. Base metal types (J, K, T, E, N) are supplied in packages of five with a 300 mm (12") standard length. In contrast, Pt/Rh types (R, S, B) are sold individually with a 150 mm (6") standard length. Model numbers follow the format Calibration-Wire Dia., such as CHAL-005 for Type K or P13R-002 for Type R. Additional wire diameters are also available for Type N upon request to Sales.
