Without electric spark, long using life, little impact on the measurement accuracy, it is not only applicable to certain dangerous places, but also suitable for frequent turn on/off occasions. It has the testing function, automatic control, and automatic warning to the liquid medium . YXG series explosion-proof inductive pressure gauge is based on GB3836.1< the request of the electric equipment used in explosive gas environment > "and GB3836.4< safe explosive gas environment electrical equipment intrinsically safety-type" I " >, and qualified the relevant departments for the national explosion test. YXG series explosion-proof inductive pressure gauge should match with safety bar P+F to be a system of intrinsically safe explosion-proof. This system is applied to 1 area and 2 area with explosive gas. 工作原理 YXG系列防爆感應(yīng)式接點(diǎn)壓力表的測(cè)量系統(tǒng)由彈簧管、機(jī)械傳動(dòng)機(jī)構(gòu)、示值部件、感應(yīng)式接點(diǎn)裝置組成。彈簧管在被測(cè)壓力作用下,產(chǎn)生彈性變形引起管端位移,其位移通過機(jī)械傳動(dòng)機(jī)構(gòu)(連桿和機(jī)芯)進(jìn)行放大,傳遞給示值部件,指針在刻度盤上指示出相應(yīng)的壓力值的同時(shí),帶動(dòng)控制片的位置發(fā)生變化,當(dāng)儀表指針與上限或下限設(shè)定指針重合時(shí),控制片影響敏感元件的電磁場(chǎng)變化,使感應(yīng)開關(guān)電氣狀態(tài)發(fā)生改變。 可在設(shè)備達(dá)到設(shè)定壓力時(shí)輸出斷(通)態(tài)信號(hào),與外部設(shè)備用適當(dāng)?shù)碾娐愤B接后便能發(fā)出所需的報(bào)警信號(hào)或開、停機(jī)等控制壓力的動(dòng)作,將系統(tǒng)壓力控制在所需范圍內(nèi)。 Operating principles The measure system of YXG series explosion-proof inductive contacts pressure gauge. Is composed by the bourdon tube, mechanical transmission system, value-show components, inductive contact device.The deformation of bourdon tube under the measuring pressure causes pipes -displacement, and the displacement is enlarged by mechanical transmission organizations(connecting rod and movement), which is transferd to value-show components. Then the value of the pressure is indicated and the position of control patch is changed. When the up and down limits set become to be coinciding, the control patch affects the electromagnetic field changes to transform the state of electrical switches. With the output of turn on/off signal, to send the alarm or start/stop machine after connecting outer equipment, control system pressure within required range. 主要技術(shù)指標(biāo) 儀表類型 Types; YXG 彈簧管標(biāo)準(zhǔn)型 YPXG 膜片標(biāo)準(zhǔn)型 YXGS 彈簧管密閉型 YPXGS 膜片密閉型 YXGN 彈簧管耐震型 YPXGN 膜片耐震型 YXG Bourdon tube standard type YPXG Diaphragm standard type YXG Bourdon tube obturation type YPXGS Diaphragm obturation type YXGN Bourdon tube vibration-proof type YPXGN Diaphragm vibration-proof type 儀表公稱直徑 Diameter:φ 100mm、φ 160mm 儀表結(jié)構(gòu)形式 Structure: ①≥ 0.1MPa 彈簧管型 ②< 0.1MPa 膜片型 ①≥ 0.1Mpa Bourdon tube type ②< 0.1Mpa Diaphragm type 控制方法 Control: 電感式接近開關(guān),輸出方式見附表 度等級(jí) Accuracy: φ 100mm 彈簧管型:(≥ 0.4MPa):1.0、1.5 級(jí)(1.6 級(jí));(< 0.4MPa 及真空):1.5 級(jí)(1.6 級(jí)); φ 160mm 彈簧管型:(≥ 0.1MPa):1.0、1.6 級(jí)(1.5 級(jí));(真空):1.6 級(jí)(1.5 級(jí)); φ 100mm 膜片型:2.5 級(jí);≥ 10kPa 1.5 級(jí)(1.6 級(jí)) φ 160mm 膜片型:1.6 級(jí)(1.5 級(jí))< 10KPa 2.5 級(jí) φ 100mm Bourdon tube type: (≥ 0.4MPa): 1.0%, 1.5%(1.6%);(< 0.4Mpa & vacuum =:1.5%(1.6%); φ 160mm Bourdon tube type: (≥ 0.1MPa): 1.0%, 1.6%;(vacuum)1.6% φ 100mm Diaphragm type: 1.5%(1.6%), 2.5%; φ 160mm Diaphragm type: 1.6%; 測(cè)量范圍 Range; ① 0~0.1 至0~60MPa、-0.1~0 各系列及任何相關(guān)正負(fù)壓聯(lián)程 ② 4kPa~100kPa、-100kPa~0 各系列及任何相關(guān)正負(fù)壓聯(lián)程 ① 0-0.1to 0-60Mpa, -0.1-0 series and compound ranges ② 4Kpa-100Kpa, -100Kpa-0 series and compound ranges 電感式接近開關(guān)電氣參數(shù)Inductance approach switch electrical parameter ①額定電壓:8VDC,安全使用電壓< 16VDC ②工作電流:通態(tài)≥ 3mA,斷態(tài)≤ 1mA,安全使用電流< 52mA ③開關(guān)頻率:< 5000Hz ① Pressure gauge fixed: 8VDC, Safe voltage < 16VDC ② Working current: Opening ≥ 3Ma,Closed ≤ 1Ma,Safe current < 52mA ③ On/off frequency < 5000Hz 工作環(huán)境溫度 Ambient temperature: 20℃~+60℃ 防爆等級(jí) Explosion-proof class: Exib Ⅱ CT6 防爆合格證號(hào)碼The code of Explosion-proof Certificate: CE052074 儀表防護(hù)等級(jí)Protection class: ①標(biāo)準(zhǔn)型:IP54 ②密閉型、耐震型:IP65 ① Standard type:IP54② Obturation & vibration-proof type:IP65 耐震型儀表填充液Liquid filling of vibration-proof instrument: 專用儀表填充液Special Instrument liquid 電感式接近開關(guān)控制方法及接線示意 Control method and wiring diagram of electric inductive approach switch
