TL-4

Supported Applications

The Omega TL-4 series consists of non-reversible temperature labels designed to provide a permanent visual indication when specific temperatures are reached. These indicators function as passive monitoring devices that change state upon exposure to heat, offering a straightforward method for verifying thermal events.

Operating Conditions & Performance

The TL-4 series is characterized by its non-reversible operation; once the label changes color or pattern at the designated temperature threshold, it remains in that changed state. The product line covers a range of activation points as indicated by the numeric suffixes in the model codes (e.g., 105, 130, up to 465). Specific performance metrics such as response time, accuracy tolerances, and ambient operating limits are not detailed in the current series documentation.

Configuration Options

The TL-4 family is available with multiple temperature setpoints. The model numbering convention includes a four-digit numeric code representing the activation temperature followed by a two-digit suffix (10 or 30). Available variants include:

• TL-4-105: Activation at 105 degrees.
• TL-4-130: Activation at 130 degrees.
• TL-4-170: Activation at 170 degrees.
• TL-4-210: Activation at 210 degrees.
• TL-4-250: Activation at 250 degrees.
• TL-4-290: Activation at 290 degrees.
• TL-4-330: Activation at 330 degrees.
• TL-4-370: Activation at 370 degrees.
• TL-4-410: Activation at 410 degrees.
• TL-4-465: Activation at 465 degrees.

Each temperature setpoint is offered in two configurations, distinguished by the suffixes "-10" and "-30." The specific functional differences between these suffix options are not defined in the available series data.

Key Product Differences

Variation within the TL-4 series is primarily driven by the selected temperature setpoint. All listed models share the same non-reversible label technology and form factor implied by the "TL" designation, differing only in their specific activation thresholds and suffix codes.
