Đo khoảng cách tuyến tính với Q4X Analog

Tiếp nối sự thành công của dòng Q4X Discrete, Q4X Analog ra đời có thể giải quyết hầu hết các ứng dụng phức tạp liên quan đến đo mức chất lỏng, chất rắn.
Chức năng "Two-point Teach" cho phép người sử dụng có thể cài đặt khoảng cách tương ứng với 0 và 10 VDC. Quá trình cài đặt chỉ mất 3 thao tác:
- Nhấn và giữ nút TEACH trong 2 giây.
- Nhấn SELECT để chọn vị trí ứng với 0V.
- Nhấn SELECT lần 2 để chọn vị trí ứng với 10V.
