Matsuo M3 10YC

Matsuo's temperature control devices contribute to energy conservation for the future of the global environment. Since the founding of Matsuo Electric Co., Ltd. in 1960, the company has adhered to a "no imitation" policy, committed to manufacturing products that others have not made. Thermal control devices have two main functions: controllers and protectors. Electronic thermostats are commonly used in laboratories and research centers, but are expensive; the Temperature Power Sensor (TPS) enables precise temperature regulation and can replace electronic thermostats; capillary thermostats were once widely used, but their applications have declined due to issues such as large physical size; TRS thermal reed switches have limitations such as limited contact capacity; disc-type thermal protectors are simple in structure and inexpensive, but their large temperature differential and other drawbacks make them unsuitable as controllers; thermal fuses are non-resettable, yet demand continues due to their simplicity and low cost.

• Electronic Thermostat: Maintains temperature within a specified range; widely used in common products; requires small ON/OFF temperature differential, high accuracy, and long service life.
• Temperature Power Sensor (TPS): Comprises a semi-permanently durable snap-action spring, a flat bimetal strip with no material strain, and two additional flat bimetal strips for enhanced sensitivity; enables precise temperature regulation.
• Disc-Type Thermal Protector: Simple structure and low cost; accounts for 80% of the global bimetal thermal protector market; however, exhibits large temperature differential and gradual set-point drift; typical service life ranges from several thousand to tens of thousands of operations.
