捷克VUHZ.A.S是世界的結(jié)晶液位傳感器制造商,產(chǎn)品廣泛地應(yīng)用于世界各大鋼廠,在中國(guó),寶鋼,鞍鋼,首鋼京唐,唐鋼,包鋼,邯鋼,湘鋼,漣鋼等大中小型鋼廠都在使用VUHZ的液位檢測(cè)產(chǎn)品.

VUHZ產(chǎn)品以其世界上的科技水平,突破了傳統(tǒng)的檢測(cè)系統(tǒng)的局限, 傳統(tǒng)的檢測(cè)系統(tǒng)一般采用Co一60或浮球檢測(cè)系統(tǒng)。其中Co—60檢測(cè)雖然精度高，但其具有放射性，需要專業(yè)人員保管和使用，安全性不高。而浮球是采用耐材制造的，會(huì)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(dòng)強(qiáng)度和中斷整個(gè)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(cè)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結(jié)晶液位控制系統(tǒng)包括有VUHZ液位傳感器SH7-S10,VUHZ前置放大器SH-P,VUHZ信號(hào)處理器SH-E,VUHZ液位傳感器電纜,VUHZ信號(hào)處理器連接電纜, VUHZ螺栓,VUHZ傳感器安裝固定底座,VUHZ傳感器保護(hù)蓋板, VUHZ絕緣保護(hù)軸套, VUHZ導(dǎo)向墊板, VUHZ絕緣墊片及VUHZ工具.

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.

VUHZ傳感器內(nèi)部基本結(jié)構(gòu)原理。由勵(lì)磁線圈S和檢測(cè)線圈L和檢測(cè)線圈R組成。勵(lì)磁采用峰峰值15V頻率800HZ的信號(hào)。由于澆注時(shí)鋼液面上有保護(hù)渣層，而此勵(lì)磁產(chǎn)生的電磁信號(hào)可以穿透10mm的渣層和18mm鋼水。但該電磁信號(hào)不能穿透銅板，因此在傳感器的其它部位使用銅質(zhì)的外殼。電磁信號(hào)經(jīng)過鋼液面反射回來分別在兩個(gè)檢測(cè)線圈上產(chǎn)生與鋼液面的高度成相應(yīng)關(guān)系的感應(yīng)電動(dòng)勢(shì)VL和VR。電動(dòng)勢(shì)Ve(Ve=VL+VR)和結(jié)晶器振動(dòng)的頻率(fo)和振幅(Fo)信號(hào)一起作為變送器的輸入信號(hào)經(jīng)過補(bǔ)償、轉(zhuǎn)換成標(biāo)準(zhǔn)的4～20mA液位信號(hào)。
