Specialized sensors are widely used in a variety of industries and applications, from consumer electronics and industrial automation to biomedical devices and anywhere in between. One of the most versatile and reliable specialized sensors are the CR6621-500. This article will provide an overview of the CR6621-500\'s application field and working principle.

Application Field of CR6621-500

The CR6621-500 is a multipurpose, IP67-rated, water-resistant, low-current LCD panel-mount sensor. It is designed to work with a wide variety of industry standard voltage levels (from 10V to 100V). It can measure both AC and DC voltages and can be used as an overvoltage protector, to switch on alarms, to detect short-circuits and insulation faults, to switch on and off relays, for lighting control in heavy industry or in automobiles, and in general for detecting dangerous levels of voltage or current. It is also suitable for use in industrial automation, monitoring, smart home automation, energy management, and factory automation.

Working Principle of CR6621-500

The CR6621-500 is based on a design similar to a comparator. The CR6621-500 has two terminals; the voltage applied to the first terminal is compared to the user set voltage which is set with a potentiometer and applied to the second terminal. If the voltage applied to the first terminal is higher than the user set voltage, the CR6621-500 will open indicating that the voltage has exceeded the user set voltage and the alarm should be switched on. If the voltage applied to the first terminal is lower than the user set voltage, the CR6621-500 will stay closed, indicating that the applied voltage is within the user set voltage.

The CR6621-500 also includes a nonvolatile memory which allows it to store the user set voltage and the detection threshold voltage. This memory allows the user to configure the CR6621-500 to remember the user set voltage even when the power to the device is switched off. This makes the CR6621-500 a robust and reliable device for monitoring voltage.

Conclusion

The CR6621-500 is a versatile and reliable specialized sensor. It can be used in a wide variety of applications for measuring AC and DC voltages, controlling lights, monitoring overloads, and detecting insulation and short-circuits. Its design includes a memory which allows the user to store the user set voltage and the detection threshold voltage even when the power to the device is switched off. With its high dependability and versatile potential for application, the CR6621-500 is an excellent choice for specialized sensing purposes.
