Supported Applications
The Omega NEP-TX series consists of Molten Metal Ceramic Sheath Thermocouple Probes with a Cast Iron Head, designed for non-ferrous molten metal applications. These probes are engineered for high wear or high impact environments and operate in processes involving aggressive aluminum lithium alloys.
- Non-ferrous molten metals
- Molten aluminum
- Aggressive aluminum lithium alloys
The series is not recommended for caustic solutions or hydrofluoric acid. Preheating of the process is not necessary.
Operating Conditions & Performance
The NEP-TX series supports a measurement range up to 1250°C (2282°F). The probe features an OMEGATITE 650 ceramic sheath, described as an alloy of silicon nitride and aluminum oxide. This material provides non-wetting, gas-tight, chemically inert, corrosion-resistant properties, along with high temperature thermal shock resistance.
Standard construction includes a cast iron NEP-TX protection head and a 1¼ NPT mounting thread. The standard probe dimensions are an overall length of 475 mm (18.75 in), a sheath diameter of 28 mm (1.10 in), a stem length of 475 mm (18.75 in), and a head length of 127 mm (5 in) with a head diameter of 41.275 mm (1⅝ in).
Configuration Options
The series offers configurable options to meet specific installation requirements:
- Sensor Calibration: Available in K and N thermocouple calibrations.
- Dual Element Configuration: Add the suffix "-DUAL" to the model number for a dual element setup; this option adds $50 to the price.
- Custom Probe Lengths: Custom lengths are available. To order in longer length, change the standard "-475" designation to the required length in mm (e.g., 1524).
The model number guide follows the format: NEP-TX-<Thermocouple Calibration>-PTRS-<Probe Length>-<Probe Diameter>. For example, a standard K-type probe is ordered as NEP-TX-K-PTRS-1628-475.
Key Product Differences
The series includes variants with different thermocouple calibrations and configurations. Standard models feature a single element, while the "-DUAL" suffix indicates a dual element configuration. The ceramic tube is packaged separately to avoid breakage during shipping; units are shipped unassembled.
