YXG系列防爆感應(yīng)式接點(diǎn)壓力表應(yīng)與P+F公司生產(chǎn)的安全柵配套使用, 可構(gòu)成本質(zhì)安全防爆系統(tǒng)。此系統(tǒng)適用于1 區(qū)和 2 區(qū)具有爆炸性氣體的區(qū)域。
The switch of YXG series explosion-proof inductive pressure gauge is inductive ap-
proach form, because of non-contact-type, it have not any spoilage to the power supply system. 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.
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??稍谠O(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)。
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.
