Using optical fibers for data transmission between sensors and converters! Achieving high-precision water level measurement.
We would like to introduce our optical quartz water level gauge, the "OPQS Series." The optical quartz water level gauge converts frequency signals from a quartz crystal oscillator into optical signals (SM) within the sensor's E/O conversion section for transmission. This product has a built-in battery inside the sensor to serve as the power supply for the sensor. The quartz crystal oscillator used in the water level measurement section changes its resonant frequency linearly in response to the applied water pressure, and due to the large rate of change, it enables highly accurate water level measurement. 【Features】 ■ High Precision: Utilizes the principle of the highly regarded quartz water level gauge for accurate water level measurement. ■ Lightning Protection: Uses optical fiber for data transmission between the sensor and the converter. *For more details, please refer to the PDF document or feel free to contact us.
