Supported Applications
The Omega Magnetic Mount Thermocouples for Ferrous Metal Surfaces (Models 88401 and 88402) are magnetized thermocouple probes designed for long-term contact pressure on ferrous metal surfaces. These sensors provide surface temperature measurement capabilities where magnetic mounting is required.
Operating Conditions & Performance
The series offers two distinct maximum service temperatures based on the model and insulation type:
- Model 88401: Rated to a maximum of 250°C (480°F), utilizing PFA-insulated lead wire.
- Model 88402: Rated to a maximum of 400°C (752°F), utilizing 'GG' fiberglass-insulated lead wire.
The probes require approximately 10 seconds to reach full surface temperature. Both models are supplied with an SMPW connector for electrical connection.
Physical Dimensions
- Model 88401: Width: 27.0 mm (1.06 in); Height: 19 mm (0.75 in); Depth: 19 mm (0.75 in).
- Model 88402: Width: 9.5 mm (0.38 in); Height: 16 mm (0.63 in); Depth: 38 mm (1.5 in).
Configuration Options
The series supports multiple thermocouple types and configurations to accommodate specific measurement needs:
- Sensor Types: Available with Type K or Type E elements.
- Housing Models: Model 88401 (PFA insulation) and Model 88402 ('GG' fiberglass insulation).
- Connector Options: Standard SMPW connector; IEC variants are available for specific models (e.g., 88401K-IEC, 88402K-IEC).
A TAS adaptor is sold separately. Replacement elements are offered for Model 88401 configurations:
- 88401K-RE: Replacement K element for 88401K.
- 88401E-RE: Replacement E element for 88401E.
Key Product Differences
The primary distinction between the two models lies in their maximum temperature rating and insulation material. Model 88401 is limited to 250°C (480°F) with PFA-insulated lead wire, while Model 88402 extends capability to 400°C (752°F) using 'GG' fiberglass-insulated lead wire.
A critical design difference affects maintenance: due to the construction of Model 88402, its element is not replaceable. Conversely, replacement elements are available for Model 8841 configurations. Both models share the same SMPW connector interface and magnetic mounting function but differ in physical dimensions as noted above.
