Specification of Rod Thermostats
Temperature Range: -35°C to 320°C.
Common ranges:
Low-temperature applications: -35°C to 100°C.
High temperatures: 50°C to 320°C (122°F to 608°F)
Temperature Differential (Hysteresis)
Definition: The difference in temperature between on and off.
Typical differential: 2°C to 10°C (3.6°F to 18°F)
Capillary tube specifications Ranges from 300mm to 3000mm (12 inches to 118 inches).
Material: They are often made from copper or stainless steel.
Diameter: Usually 1mm to 2mm (0.04 to 0.08 inches).
Sensing Bulb Specifications
Material: Made from stainless steel or copper for thermal conductivity and corrosion resistance.
Diameter: 6mm to 8mm (0.24 to 0.31 inches).
Length: Usually between 60mm and 200mm (2.4 inches and 7.9 inches).
Electrical Ratings
Voltage: Designed for 120V, 240V, or 400V AC systems.
Current: Rated to handle 6A, 10A, 16A, or higher.
Power: Typically between 500W to 3000W.
Switch Type:
Single Pole Single Throw (SPST): Simple on/off control.
Single Pole Double Throw (SPDT): Allows for two different circuits to be controlled.
Control the temperature accurately: The capillary thermostat controls temperature very precisely, making it suitable for applications that require high-precision temperature regulation.
Mechanical operation: The capillary thermostat can operate without a power source, even if there is no power or it is unstable.
Cost-effective: Capillary thermostats are usually cheaper than electronic ones and better for projects with limited budgets.
Reliable and durable: Capillary thermostats last a long time and don't get affected by things like electromagnetic interference.
Easy to install and maintain: It's simple to install and maintain, reducing complexity and costs.
Can be adapted easily: Suitable for household appliances, industrial equipment and heating systems.
Can be used in a wide temperature range.
Fast response: It responds quickly to temperature changes.
