The WIKA TFS35 temperature switch is an industrial device designed for temperature monitoring and control. It is used to limit or regulate the temperature of machinery and equipment to prevent overheating or damage. The temperature switch automatically activates or deactivates equipment like fans, pumps, or other systems based on predefined temperature thresholds. It features bimetallic elements, which are the core technology for detecting temperature changes and triggering the switch at the appropriate moment.

Features:

• Fixed Switching Temperature: The device is set to trigger a response when a specific temperature is reached, typically the nominal switching temperature (NST).
• Automatic Reset: The device resets itself when the temperature cools down to the reset switching temperature (RST), typically 15 to 40 K below the switching temperature.
• No Additional Voltage Supply: The temperature switch does not require an external power source to operate.
• Switching Voltages up to AC 48 V / 3 A: The TFS35 can handle a variety of switching applications, supporting voltages up to 48 V AC and currents up to 3 A.

Applications:

• Machine Building: Used in industrial machines to ensure they operate within safe temperature ranges.
• Compressors: Controls the temperature of compressors, preventing overheating and failure.
• Pumps: Protects pumps by activating cooling systems or shutting them down in case of excessive heat.
• Cooling and Heating Circuits: Monitors and controls temperature in systems that require precise thermal regulation.
• Mobile Hydraulics: Used in mobile hydraulic systems to avoid damage due to high temperatures.

Function: The temperature switch operates through the bending of a bimetallic disc that acts as the sensing element. When the temperature reaches the nominal switching temperature (NST), the bimetallic disc bends and causes the contact to either open or close. Upon cooling below the reset switching temperature (RST), the disc resets, and the switch returns to its original state.

Contact Design Options:

1. Normally Closed (NC): In this configuration, the contacts are closed in the normal state, and the switch opens the circuit to shut down the machinery once the set temperature is exceeded.
2. Normally Open (NO): In this configuration, the contacts are open under normal conditions, and when the temperature reaches the switching threshold, the circuit closes to activate a device like a fan or warning light.

Once the temperature falls below the reset switching temperature, the contacts return to their initial state, ensuring the machinery can resume normal operation.
