HSTC

Supported Applications

The Omega HSTC series consists of hermetically sealed tip insulated thermocouples designed for sanitary applications. These ready-made PFA-insulated sensors are engineered to offer chemical and oil resistance, electrical insulation, ease of cleaning, and sterilization capabilities.

Operating Conditions & Performance

The HSTC series operates within a measurement range of -200°C to 250°C (-328°F to 482°F), with an operating process temperature up to 250°C (482°F). Accuracy meets or exceeds IEC 60584-2, Tolerance Class 1, specified as ±1.5°C or ±1.5% of reading (whichever is greater).

The sensor tip diameter measures 1.6 mm (0.063 in), providing a fast response due to the small size. The wetted material and sheath are constructed from PFA, which provides high resilience against chemicals and oils.

Configuration Options

The series supports multiple thermocouple calibrations including Type J, K, T, or E. Configurations vary by wire gauge, length, and electrical connection type.

• Wire Gauge: Standard 24 AWG stranded; a 20 AWG stranded version is available for longer lengths at additional cost.
• Lengths: Available in various standard lengths (e.g., 1 m/40", 2 m/80", 3 m/120") and custom lengths. An option exists to add 300 mm (12") of TT wire for additional cost.
• Electrical Connections: Standard stripped leads or optional connectors including SMPW-CC ultimate connector, OSTW-CC ultimate connector, and the MWTC-D-K-915 miniature wireless smart connector series for wireless transmission.
• Housing/Overbraid: Metal overbraid is available as an option.

The model number construction follows the format HSTC-TT-<CALIBRATION>-<LENGTH>-<CONNECTOR>. For example, replacing 'SMPW' with 'OSTW' in the model number orders a full-size connector at no additional charge.

Key Product Differences

Variants within the HSTC series are distinguished by thermocouple type (J, K, T, E), wire gauge (24S vs. 20S), and termination style. Models ending in stripped leads provide bare ends for direct connection or custom wiring.

• Connector Options: Variants with the SMPW-CC suffix include an ultimate mini male connector with strain relief; variants with OSTW-CC feature a full-size connector.
• Wireless Option: Specific configurations support wireless transmission via the MWTC-D-K-915 miniature wireless smart connector series.
