阿波羅飛船、波音747、空客A320、F22、F117等產品制造。
壓力開關采用*精度、*穩(wěn)定**的壓力傳感器和變送電路，
. Since the light emitting diode (LED) is used for the light assembly for 24 VDC, there are 2 terminals and polarity. One is “+”
再經專用 CPU模塊化信號處理技術，實現(xiàn)對介質壓力信號的檢測、顯示、報警和控制信號輸出。
If water or oil were to make an ingress, the electrical circuit would be corroded and result in a malfunction or damage.
 Operating fluids are either air or inert gas exclusively. Never use liquids.
 Never use in an environment where flammable fluid or gas is used. Use of this product near flammable materials
could cause an explosive situation. This product is not explosion-proof.
Air/Inert gas 1.0 MPa 0.8 MPa 0.1 to 0.7 MPa –5 to 60°C (No freezing) 1ab ±0.1 MPa 0.05 MPa or less ±0.05 MPa Equivalent to IP40 0.15 kg
0 1 Micro switch load type
設置范圍：全量程段可以設置
可廣泛用于石油、化工、冶金、電力、供水等領域中對各種氣體、
防護等級：IP65
壓力開關采用的彈性元件有單圈彈簧管、膜片、膜盒及波紋管等。
供電電壓：12~35V DC(24V DC 校準電壓)/交流220vAC供電
采樣速率：10次/秒(可以根據客戶需要定制要求的速度)。
接口螺紋：M201.5、G1/4、G1/2、1/4NPT(可以根據客戶需要定制)
壓力開關采用的彈性元件有單圈彈簧管、膜片、膜盒及波紋管等。
 Use a flat head screwdriver to set the pressure. Then, lock it in place with the lock nut. Otherwise the set pressure will change.
 The hysteresis (the ON-OFF range) is fixed. 4. Set pressure scale is the value when pressure increases.
Do not use in an environment, where water or oil is splashed. Because it is the open type construction.
壓力開關的工作原理：是當系統(tǒng)內壓力*于或低于額定的安全壓力時，
 for red load wire and the other is “–” for black load wire. Light will not light up if wired incorrectly.
量程范圍：-100Kpa～200MPa;
液體的表壓、絕壓的測量控制，是工業(yè)現(xiàn)場理想的智能化測控儀表。
壓力開關廣泛用于航空航天和**領域，如M1A1坦克、
 Light ass'y for 24 VDC has 3 mA of current leakage. Connect the LED directly to the power supply
 if the input of the PLC sees the switch as closed at all times due to leakage
Turn the adjusting screw on the cover to set the pressure with a flat head screwdriver. Fix the screw with locking nut after adjusting.
 Hysteresis is a fixed value. Increase the setting value by turning to “+” (H) side. Decrease the setting value by turning to “–” (L) side.
監(jiān)測點：防波動回差設置。
使用溫度：-20℃—85℃;
輸出繼電器容量：380V 3A, 220V 5A，24V DC 5A等
精 度：優(yōu)于0.0.5%FS、1%FS等各種
With gasket Rc 1/4 NPT 1/4
感應器內碟片瞬時發(fā)生移動，通過連接導桿推動開關接頭接通或斷開，
當壓力降至或升額定的恢復值時，碟片瞬復位，開關自動復位，
或者簡單的說是當被測壓力超過額定值時，彈性元件的自由端產生位移，
直接或經過比較后推動開關元件，改變開關元件的通斷狀態(tài)，達到控制被測壓力的目的。
