Tính năng, đặc điểm
Cảm biến lưu lượng OF-Z phù hợp để đo dầu (dầu nặng, dầu nhẹ, dầu nóng, v.v.).
Nó là một cảm biến lưu lượng với các bánh răng hình elip đo
microflow với độ chính xác cao.

  • Các biện pháp nặng, nhẹ, dầu nóng, vv
  • Đo phạm vi microflow bằng công nghệ sản xuất vượt trội.
  • Tốt trong việc đo lưu lượng xung.
  • Bộ cảm biến từ tích hợp của bộ khuếch đại, mạnh chống nhiễu, là đầu ra tỷ lệ với tốc độ dòng chảy.
  • Ngõ ra xung bằng bộ thu mở hoặc xung điện áp.
  • Đo phạm vi tốc độ dòng chảy rộng với độ chính xác cao.
  • Cấu trúc đơn giản do các bánh răng hình elip được sử dụng làm nguyên tắc đo.
  • Có khả năng đo các chất lỏng khác nhau.
  • Khiếu nại RoHS (Tuân thủ chỉ thị RoHS để giải quyết các vấn đề môi trường.)
