Mechanical Temperature Switch

Temperature Switch

The Mechanical Temperature Switch is a rugged and reliable sensing device designed for temperature monitoring in industrial fluid systems. Operating on the proven bimetallic principle, it features a curved bimetallic element that expands upon heating to trigger a high-capacity internal mechanical switch. With a full brass construction for all wetted parts and an IP65 protection rating, this switch is engineered for durability in hydraulic and lubrication environments. It offers a cost-effective, no-power-required solution for detecting over-temperature or under-temperature conditions in demanding machinery applications.

Description

Overview of Mechanical Temperature Switch

The Mechanical Temperature Switch is a robust mechanical instrument designed to monitor and control temperature limits in industrial pipelines and reservoirs.

What is it? This switch utilizes a bimetallic strip formed into a circular curve. When the medium temperature reaches the factory-preset value, the thermal expansion of the bimetal strip triggers an internal mechanical mechanism, causing the electrical contact to actuate. It does not require a dedicated power supply to operate the sensing element, making it a highly reliable safety component.

Main Application Field: It is specifically designed to meet the diverse temperature control requirements in hydraulic systems, lubrication systems, and traditional transmission systems. It is primarily used to detect whether the temperature has exceeded the maximum limit or fallen below the minimum limit to protect equipment.

Key Characteristics The device features a heavy-duty brass wetted structure and is available with G1/2, G1/4, or M20x1.5 thread options. It is characterized by its high contact capacity (up to 16A), enabling it to directly control high-load AC circuits. The black BNR housing provides IP65 protection, ensuring stability in oily and dusty industrial environments.

Features of Mechanical Temperature Switch

Proven Bimetallic Principle: Simple and reliable mechanical structure that triggers the switch based on thermal expansion, offering long-term operational stability.
High Contact Capacity: Equipped with silver-plated contacts capable of handling up to 16A at 220VAC, suitable for direct load switching.
Durable Wetted Materials: All parts in contact with the medium are made of high-quality brass, providing excellent thermal conductivity and corrosion resistance.
Flexible Output Options: Available in both Normally Open (NO) and Normally Closed (NC) configurations to suit different control logic requirements.
No External Power Needed: As a mechanical device, the sensing element operates independently of a power source, enhancing system safety during power failures.
Robust Protection: Rated at IP65 with a durable BNR shell, making it resistant to water jets and oil contamination common in machinery rooms.

Applications of Mechanical Temperature Switch

Hydraulic Systems: Monitoring hydraulic oil temperature to prevent thinning and component wear.
Lubrication Systems: Ensuring lubricating oil stays within the optimal temperature range for bearings and gears.
Transmission Systems: Protecting gearboxes and drive units from overheating during continuous operation.
Industrial Cooling: Activating cooling fans or heat exchanger valves when setpoints are reached.
Pump Protection: Preventing pumps from operating at extreme temperatures that could damage seals.

Price of Mechanical Temperature Switch

The price of the Mechanical Temperature Switch varies depending on the specific fixed setpoint (between 30 and 120 degrees Celsius), thread type, and contact configuration. Product prices will change based on these technical parameters.
