Heating element thermal protector Sonde SF

ETFEsiliconePP

Product description
The SF Probe is a fusible safety probe designed to protect thermal equipment from excessive temperatures. It features a flexible FEP-coated cable with two silicone-insulated conductors and a fusible element that is irreversibly destroyed when the critical temperature is reached (94°C or 121°C depending on the model). The device immediately interrupts the control circuit to prevent fire risk or severe overheating.

Key benefits

• Immediate control-circuit interruption in case of overheating
• Simple in-service installation on immersion heaters
• Irreversible operation without reset for fail-safe protection
• Two models available to match process temperature requirements

Main applications

• Protection of immersion heaters in chemical and electrolytic baths
• Securing industrial heating systems
• Use in environments with thermal hazards
• Applications with aqueous and viscous liquids
