SA1

Supported Applications

The Omega SA1 series consists of self-adhesive polyimide fast response surface thermocouples designed for rapid temperature measurements on flat surfaces. These sensors feature a 'ribbon type' hot junction secured between high-temperature fiberglass cloth and electrically insulating polyimide film, enabling installation without epoxy or cement. The product overview specifies use cases requiring quick thermal conductivity and electrical insulation.

Key application constraints include:

• Surface Temperature Measurement: Designed for direct contact with surfaces up to the rated temperature limits.
• Non-Human Use: The documentation explicitly states these products are not designed for, and should not be used for, human applications.
• Temporary or Semi-Permanent Mounting: The silicone polymer adhesive backing allows for easy installation and removal; however, it is noted that the backing was designed for easy removal but not for repetitive reapplication.

Operating Conditions & Performance

The SA1 series operates within a temperature range of -60° to 177°C (-75° to 350°F) as defined by the pad and adhesive material ratings. The thermocouple wire itself is limited by individual type ratings; for example, long-term use of Type T (30 AWG) is noted as limited to 149°C [300°F].

Performance specifications include:

• Response Time: Better than 0.3 Second.
• Accuracy Class: Meets or exceeds Special Limit of Error (SLE) and EN 60584-2 Tolerance Class 1.
• Long-Term Rating: Rated to 175°C (350°F) long term.

The sensors utilize 30 AWG PFA-coated thermocouple wire. Electrical connection requires connecting the red wire to the positive terminal and the black wire to the negative terminal of a temperature measuring device.

Configuration Options

The SA1 series offers configurable options across sensor types, lead lengths, terminations, and packaging accessories. The model number structure follows the pattern SA1---.

Sensor Types (Calibrations)

• Type J
• Type K
• Type T
• Type E

Lead Lengths and Wire Specifications

The series supports multiple lead lengths with 30 AWG (0.010" dia) PFA-coated wire:

• Standard Lengths: 1 m (40") is the base length.
• Extended Lengths: 2 m (80") and 3 m (120") are available options.

Termination Options

Sensors can be ordered with stripped ends or molded strain relief connectors:

• Stripped Ends: Standard termination for direct connection to measuring devices.
• SMP Male Connector: Available via the -SRTC suffix (molded strain relief).
• M12 Connectors: Options include male straight M12 plug (M12-S-M) or male right-angled M12 plug (M12-R-M). These are added to the model number for additional cost.

Accessories and Packaging

• Packaging: Probes are typically supplied in packages of 5 (e.g., -SC variants).
• Spool Caddy: Available for convenient storage, specifically noted with the miniature connector and spool caddy configurations. Note that 2 m (80") is the longest length available with a spool caddy.

Physical Dimensions

The sensor pad dimensions are specified as:

• Pad Size: 19 x 25 x 0.3 mm (0.75 x 1.00 x 0.012").
• Overall Width/Height: 13 mm (0.5 in) wide, 19 mm (0.8 in) tall.
• Thickness: 0.5 mm (0.02 in).

Key Product Differences

Variants within the SA1 series are distinguished by thermocouple type, lead length code, and termination style.

• Type Designation: The first suffix indicates calibration (J, K, T, or E).
• Length Codes: Numeric suffixes denote wire length: -72 for 2 m (80") and -120 for 3 m (120"). Models without a numeric suffix default to the standard 1 m (40") length.
• Connector Suffixes: The -SRTC suffix indicates an SMP male connector with molded strain relief. Variants ending in -SC include a miniature connector and spool caddy package of 5 probes.
