TC622CPA

Temperature Sensors are electronic components that measure temperature, and Thermostats are used to control these particles by operating them remotely, typically through an electrical switch. The TC622CPA Solid State Temperature Sensor and Thermostat is an integrated solution of temperature sensing and thermal management. It includes a precise temperature sensor that can measure temperatures up to 185°F (85°C) with accuracy of ±2°F (±1°C). It also includes a precision-molded thermoplastic silver DPDT snap-action switch that can switch up to 8 amps at 36 VDC, and offers reliable switching operation. The TC622CPA features excellent repeatability, low hysteresis, and unmatched precision.

Application Field

The TC622CPA is a versatile temperature sensor and thermostat ideal for a variety of application fields. It is commonly used in HVAC systems, medical equipment, process control, automation and robotics, and power electronics. It can also be used in industrial applications such as furnaces, ovens, motors, pumps, and compressors. Additionally, it can also be used in automotive applications such as engine control systems, air conditioning systems, and engine cooling systems.

Working Principle

The TC622CPA is a temperature-sensitive device that works using the NTC Thermistor effect. It contains a thermistor element that can vary its resistance depending on the temperature around it. The resistance value of the element changes in response to external temperature, which is measured by the integrated circuit and converted to a corresponding temperature reading. When the temperature exceeds or drops below the set temperature limits, the integrated circuit sends a signal to the switch, which in turn activates its output. This signals the user-installed relay or other actuation device to operate.

Conclusion

The lightweight yet powerful TC622CPA is a reliable and accurate temperature sensor and thermostat that offers repeatability, low hysteresis, and unmatched precision. It can be used in a broad range of applications from HVAC to automotive, and its thermistor-based sensing element allows for highly accurate and responsive temperature measurement.
