Specialized Sensors: CR6230-250-20 application field and working principle

The CR6230-250-20 (CR) is a specialized sensor designed by Taiyo Yuden Co., Ltd. (TYC) for industrial applications. It is a surface-mountable sensor that is capable of accurately detecting and measuring small objects or signals in various applications. It is equipped with an analog output that can be used as part of a closed loop control system or as a stand-alone sensor element.

The CR is typically used in industrial control applications for measuring temperature, displacement, pressure, vacuum, and other physical parameters. In addition, it can be used to measure various chemical and biological parameters such as pH, oxygen, carbon dioxide, and other substances present in an environment. The CR can also be used for electronic monitoring and control, such as in industrial automation and robotics.

The working principle of the CR involves sensing the presence or absence of a specific signal. When in the presence of a signal, the sensor outputs an electrical signal to the measuring device. The sensor output is linearized with respect to the signal, thus, enabling accurate and reliable measurement to be taken.

The CR consists of two parts: a sensing element and a signal processing unit. The sensing element is a surface acoustic wave (SAW) device consisting of two interdigitated electrodes with a dielectric material in between. The signal processing unit is an analog-to-digital converter (ADC) that converts the signal into a digital signal. This digital signal is then used to power the measuring device, such as a computer.

The SAW device is fabricated to a specific frequency and is subject to varying thermal expansion and contraction. This thermal expansion and contraction causes the SAW frequency to vary slightly, which in turn affects the signal output of the device. The ADC measures the signal output and corrects for these changes, allowing the signal to remain accurate and reliable.

The CR is a reliable and precise sensor for industrial control applications. Its linear output and high-sensitivity make it ideal for measuring physical and chemical parameters in an industrial environment. The combination of the sensing element and the signal processing unit allows the device to accurately measure small objects or signals and to be used in closed loop control systems.
