Supported Applications
The Omega TSW-TT Series consists of bi-metal immersion temperature switches designed for low voltage and low current applications requiring economical temperature control. These devices activate with a rise in temperature, providing direct action switching suitable for environments rated NEMA 4 and NEMA 13.
Operating Conditions & Performance
The series offers factory-preset setpoints ranging from 4 to 149°C (40 to 300°F) with a tolerance of ±2.8°C (5°F). The maximum process temperature is rated at 163°C (325°F), and the switches are designed to withstand an external pressure up to 5000 psi. Electrical performance includes current ratings of 3 A @ 240 Vac or 2 A @ 24 Vdc for resistive loads.
Key physical specifications include:
- Probe Diameter: ø9.5 mm (0.38 in)
- Insertion Length: 25.4 mm (1")
- Process Connection: ¼ NPT male
- Electrical Connection: 152.4 mm (6") wire leads
Contact and Circuit Details
The switches feature gold diffused fine silver contacts with minimum hysteresis. The circuit form is available as SPST-NO or SPST-NC depending on the specific model selection.
Configuration Options
The TSW-TT series provides a comprehensive range of fixed setpoints to accommodate diverse control points within the 4°C (40°F) to 149°C (300°F) envelope. Variants are distinguished by their contact configuration and specific temperature activation point.
- Contact Types: Models are available with Normally Open (NO) or Normally Closed (NC) contacts.
- Setpoint Increments: Factory-preset options cover the full range in 10°F increments, starting at 4°C (40°F) and extending to 149°C (300°F).
- Housing Rating: All variants are suitable for NEMA 4 and NEMA 13 environments.
Key Product Differences
The primary distinction between models in the TSW-TT series is the contact state (Normally Open vs. Normally Closed) and the specific setpoint temperature encoded in the model number. The ordering pattern follows TSW-TT-F<CONTACT_TYPE><SETPOINT>0R/WL.
- Normally Open Models: Identified by the suffix "F3A" (e.g., TSW-TT-F3A-100R/WL for 4°C/40°F).
- Normally Closed Models: Identified by the suffix "F3B" (e.g., TSW-TT-F3B-100R/WL for 4°C/40°F).
The series carries RoHS compliance and includes a 1 YEAR WARRANTY. Specific wetted materials, sheath material, or housing material are not specified in the source documentation.
