    VUHZ液位傳感器
    捷克VUHZ A.S公司,其前生是捷克鋼鐵研究,改制之后成為VUHZ A.S,是世界的連鑄機(jī)結(jié)晶液位系統(tǒng)制造商,以其世界上的科技水平突破了傳統(tǒng)的檢測系統(tǒng)的局限 傳統(tǒng)的檢測系統(tǒng)一般采用Co一60或浮球檢測系統(tǒng)。其中Co—60檢測雖然精度高,但其具有放射性,需要人員保管和使用,安全性不高。而浮球是采用耐材制造的,會受到鋼水的侵蝕,需定期人為更換和預(yù)熱,增加操作人員的勞動強(qiáng)度和中斷整個控制系統(tǒng)降低鑄機(jī)的效率。VUHZ公司電磁感應(yīng)式傳感器,測量范圍為0~160mm。VUHZ傳感器安裝在結(jié)晶器的頂部。冷卻系統(tǒng)采用直接用鑄機(jī)的一次冷卻水閉環(huán)冷卻,幾乎不用另增設(shè)備。
    VUHZ A.S結(jié)晶液位系統(tǒng)是由前端的液位傳感器,中端的信號放大器及尾端的信號處理器組成。液位傳感器感應(yīng)到鋼水液位后,通過連接電纜,把信號傳輸?shù)叫盘柗糯笃?,信號放大以后,再把信號傳輸?shù)叫盘柼幚砥?,信號處理器收到信號后?jīng)過分析處理,對連鑄機(jī)的生產(chǎn)過程作出。

    VUHZ A.S Mold level measurement is not sensitive to local meniscus disturbances such as vortices caused by argon blowing various types of waves etc. Sensor&s viewing field width is approx. 600 mm and sensor measures mean molten steel level at this section of the mold&s width. Typical course of characteristic is shown in.
    2.3 Electromagnetic sensor SH7-S10
    The sensor has shape of prism. The sensor is made of stainless non-ferromagnetic steel. Two sensing coils are located symmetrically to the axis.
    The sensor is fastened to the mold by means of sensor cover which serves as a clamp and which protects the sensor as well. The sensor cover is screwed on to two special holders fixed to the water jacket – see chapter 4. The cable between sensor and pre-amplifier may consist of two parts. Flexible cable is firmly soldered to each sensor. On the mold top an intermediate connector coupling may be placed which is connected with pre-amplifier by second part of the cable.
