GDSD500射頻導(dǎo)納物位開(kāi)關(guān)GDSD500RADIO FREQUENCY(RF) ADMITTANCE LEVEL CONTROLLER概述 IntroductionGDSD500系列射頻導(dǎo)納物位開(kāi)關(guān)是一種新穎的物位測(cè)量?jī)x表，它采用先進(jìn)的射頻導(dǎo)納技術(shù)，克服了電容式物位計(jì)不能消除導(dǎo)電掛料影響的缺陷，儀表具有運(yùn)行可靠，適用于幾乎所有工業(yè)現(xiàn)場(chǎng)。儀表還具有安裝方便，免維護(hù)，低價(jià)位等特點(diǎn), 廣泛用于石油、化工、冶金、醫(yī)藥、電力、食品、造紙等工業(yè)領(lǐng)域。 GDSD500series RF admittance level controller is a new level instrument.It adopts advantage RF admittance technology and overcomes the defect that capacitive level transmitter cant eliminate the influence of conductivc coating on sensor.Due to its stable operating ,it is used in almost all the industry site.With easy installing、no maintainence、low price ，the instrument is applied forpetroleum 、chemical engineering、 metallurgy 、pharmacy 、electric power、 foodstuff and paper product.結(jié)構(gòu)原理 Construction Principle該物位開(kāi)關(guān)由傳感器單元和電子單元組成。傳感器單元主要包括三部分：測(cè)量探極、屏蔽極及接地端。物料的高度反映為探極與容器壁間導(dǎo)納的變化，當(dāng)物料到達(dá)開(kāi)關(guān)工作點(diǎn)時(shí)，電子單元作出反應(yīng)，驅(qū)動(dòng)繼電器動(dòng)作，輸出開(kāi)關(guān)信號(hào)。屏蔽極可防止由于電極上有掛料而產(chǎn)生誤動(dòng)作信號(hào)，僅當(dāng)物料真正達(dá)到設(shè)置點(diǎn)時(shí)，繼電器才輸出信號(hào)。The controller consist of sensor and circuit .The sensor has three parts: measuring detector、 shielding detector and groundterminal.The change of admittance between detector and tank wall reflects to material height.When material height reachs controllerworking point,electric part acts to make the relay output switch signal.The shielding detector can prevent conductivc coating onsensor from error action.Only material height reachs set point really,the relay outputs the signal.參數(shù) Parameters特點(diǎn)：開(kāi)關(guān)控制，射頻導(dǎo)納原理，NULL-KOTE抗粘附電子線(xiàn)路。Characteristic:switch control,RF admittance principle, NULL-KOTE resist-adherence electric circuit電源：220VAC 50/60Hz 或24VDC 100mAPower: 220VAC 50/60Hz or 24VDC 100mA繼電器容量：DPDT，117/220VAC,5A無(wú)感3A有感Relay capacity: DPDT, 117/220VAC,5A non-inductive 3A inductive靈敏度：小于0.3pFSensitivity:less than 0.3pF探頭耐溫：-184+260Detector rating Temp.: -184+260電路部分耐溫：-40+80Circuit part rating Temp.: -40+80失電保護(hù)模式：采用高低模式，現(xiàn)場(chǎng)可調(diào)Fail-Safe: adopt high-low mode, adjustable at site延時(shí)可調(diào)：0-30秒Delay adjustable:0-30s防爆等級(jí)Explosion proof classification:本安型Intrinsically safe type:ExiaIICT4-CT6； 隔爆型Explosion proof typeExdIICT4-CT6型號(hào)規(guī)格表 Model & SpecGDSD500-射頻導(dǎo)納物位開(kāi)關(guān) RF admittance level controller224VDC供電方式Power Supply3220VACA標(biāo)準(zhǔn)靈敏度standard sensitivity電路單元靈敏度Circuit sensitivityB高靈敏度 high sensitivity0無(wú)延時(shí)(標(biāo)準(zhǔn)電路單元)no delay(standard circuit)時(shí)間延時(shí)Time delay1帶延時(shí)(0-30秒可調(diào))delay(0-30s adjustable)Y一體式integration儀表形式Instrument typeF分體式disintergration0G1螺紋式Screw:管螺紋Pipe screw過(guò)程連接Process connecting1G1 1/42G1 1/23DN40 PN1.6法蘭式Flange4DN50 PN1.65DN80 PN1.66按客戶(hù)要求According to customers requestP普通型Normal防爆等級(jí)Explosion proof classificationD隔爆型Explosive-proofB本安型Essential-proof01標(biāo)準(zhǔn)型（溫度121）standard電極形式detector type02高溫型（溫度15m的場(chǎng)合Used in high/low material level length 15m circumstance82/常壓15m 4.7mm/304ss和橡膠1NPT05耐腐型proof errosion用于液體、輕漿體、顆粒（密度240kg/m3)Used for liquid、slurry、TSP121/1.38MPa457mm（18)914mm（36)9.5mm/316ss和PTFE3/4NPT備注：以上為標(biāo)準(zhǔn)長(zhǎng)度，可根據(jù)用戶(hù)要求開(kāi)關(guān)長(zhǎng)度生產(chǎn)Remark:above is standard length, detail length is decided by customer外形尺寸圖 Outline dimensions接線(xiàn)端子圖 Wiring推薦選型安裝 Recommend Installment1）在測(cè)非導(dǎo)電介質(zhì)時(shí)，可以為水平或垂直安裝。如需要垂直安裝時(shí)，要求探頭長(zhǎng)至少大于控制位置6左右。 Horizontal or vertical installment is allowed for non-conductive material. If vertical installment, detector length must more than controlled point 6.2）在測(cè)導(dǎo)電液體、泥漿或界面檢測(cè)時(shí)，可以水平垂直安裝。探頭與物料接觸位置即報(bào)警位置。 Horizontal or vertical installment is allowed for conductive liquid slurry or interface.The position of the detector and material contacting is alarming position.3）在測(cè)粉末和顆粒裝物料時(shí)，可以水平或垂直安裝，但探頭穿過(guò)容器時(shí)，保護(hù)電極應(yīng)比容器壁上的積料厚度長(zhǎng)出2。 如用戶(hù)需要，我們可以提供材質(zhì)為T(mén)eflon或Kyanr材料的防腐探頭（采用涂層法蘭連接）。 Horizontal or vertical installment for measuring fine power and particles.Pay attention:when the detector enter into the vessel, the length of the protection detector is longer 2than the thickness of particles on the vessel.If customer require,we can supply erosion-proof detector made by Teflon or Kyanr.校準(zhǔn) Calibrition1）靈敏度的校正Adjustment for sensitivity 當(dāng)進(jìn)行調(diào)節(jié)時(shí)，請(qǐng)注意這些總的規(guī)則： 將2個(gè)靈敏度調(diào)節(jié)電位器順時(shí)針旋轉(zhuǎn)增加靈敏度。 當(dāng)兩個(gè)靈敏度控制調(diào)好后，綠色燈亮，表示探頭上“有”物料存在，紅色燈亮，表示“無(wú)”物料存在。 安裝方法有水平或垂直兩種。為保證設(shè)備穩(wěn)定工作應(yīng)有5分鐘預(yù)熱。 Pay attention below rules when adjusting: Add sensitivity through clockwise rotating both sensitivity resistance. After finishing adjustment,green light working shows there exist material on the detector;red light working shows no material . Two installment can be selected: horizontal & vertical.To keep 5 minutes warm-up to ensure the instrument work steadily. A）測(cè)量非導(dǎo)電物料，調(diào)節(jié)細(xì)（F）靈敏度控制到中間位置。然后慢慢調(diào)節(jié)粗（C）靈敏度直到狀態(tài)燈剛剛變紅。重調(diào)細(xì)（F）靈敏度控制找到一個(gè)剛剛變紅點(diǎn)，記下“空”的位置，如圖所示。然后，將探頭插入物料重調(diào)細(xì)（F）靈敏度控制（不接觸粗調(diào)靈敏度）剛好變?yōu)榫G點(diǎn)，并記下它的位置。注意兩個(gè)記號(hào)的不同，并且重調(diào)細(xì)（F）靈敏度控制到兩記號(hào)的中間位置。這就是一個(gè)完整的調(diào)試過(guò)程。To measure non-conduct material ,adjust F resistance to middle position,then adjust C resistance slowly until status light beginning to change red, repeat to adjust F to find a position which status light begins to change red,remark emptyposition; put the detector into the material, adjust F again to make the statue light change to blue,remark this position.Pay attention both different position,repeat to adjust F to between above position.All above is complete adjusting process.注意：細(xì)調(diào)可旋轉(zhuǎn)的角度應(yīng)有20度，如果少于20度，請(qǐng)與廠(chǎng)家商量。建議對(duì)于非水基工藝液體（不導(dǎo)電液體）最好 的安裝方法是垂直安裝，當(dāng)液體到達(dá)探頭10cm時(shí)報(bào)警。Remark: the rotating range of F is more than 20 degree,if less than 20,pls contact with manufacture.The best installment for non-conduct is vertical ,the controller outputs alarming signal as level reaches the detector 10cm. B）對(duì)于水基液體（導(dǎo)電液體）（金屬容器）：反時(shí)針調(diào)節(jié)靈敏度粗調(diào)（G）至最大，因?yàn)樗后w容易測(cè)量，只需碰到傳感探頭即可，這個(gè)過(guò)程提供最大的抗粘附能力。這是個(gè)完整的調(diào)節(jié)過(guò)程。To measure conduct material (metal vessel ): contrarotate G to max, due to measuring non-conduct easily, it is ok to only touch the detector,this process supply maximum anti-adhesion capability.This is a complete adjusting process.C)對(duì)于水基液體（導(dǎo)電）（非金屬容器）：參照A），但細(xì)調(diào)（F）為正好綠色位置。（有料）To measure conduct material(non-metal vessel): refer to A）,but F is in the position which status light begins to change green.2） 時(shí)間延時(shí) Time DelayGDSD500包括0-30秒可調(diào)時(shí)間延時(shí)，有延時(shí)開(kāi)/延時(shí)關(guān)模式。這種模式典型的用處是消除控制繼電器的“抖動(dòng)”，或者控制循環(huán)順序。GDSD500 have 0-30s adjustable time delay and delay-open/delay-close .It can eliminate control-relay dithering or control recursive sequence. 開(kāi)始時(shí)延時(shí)控制設(shè)為零（反時(shí)針到底位置）。當(dāng)用延時(shí)來(lái)消除繼電器抖
