阿波罗飞船、波音747、空客A320、F22、F117等产品制造。
压力开关采用*精度、*稳定**的压力传感器和变送电路，
. Since the light emitting diode (LED) is used for the light assembly for 24 VDC, there are 2 terminals and polarity. One is “+”
再经专用 CPU模块化信号处理技术，实现对介质压力信号的检测、显示、报警和控制信号输出。
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
设置范围：全量程段可以设置
可广泛用于石油、化工、冶金、电力、供水等领域中对各种气体、
防护等级：IP65
压力开关采用的弹性元件有单圈弹簧管、膜片、膜盒及波纹管等。
供电电压：12~35V DC(24V DC 校准电压)/交流220vAC供电
采样速率：10次/秒(可以根据客户需要定制要求的速度)。
接口螺纹：M201.5、G1/4、G1/2、1/4NPT(可以根据客户需要定制)
压力开关采用的弹性元件有单圈弹簧管、膜片、膜盒及波纹管等。
 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.
压力开关的工作原理：是当系统内压力*于或低于额定的安全压力时，
 for red load wire and the other is “–” for black load wire. Light will not light up if wired incorrectly.
量程范围：-100Kpa～200MPa;
液体的表压、绝压的测量控制，是工业现场理想的智能化测控仪表。
压力开关广泛用于航空航天和**领域，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.
监测点：防波动回差设置。
使用温度：-20℃—85℃;
输出继电器容量：380V 3A, 220V 5A，24V DC 5A等
精 度：优于0.0.5%FS、1%FS等各种
With gasket Rc 1/4 NPT 1/4
感应器内碟片瞬时发生移动，通过连接导杆推动开关接头接通或断开，
当压力降至或升额定的恢复值时，碟片瞬复位，开关自动复位，
或者简单的说是当被测压力超过额定值时，弹性元件的自由端产生位移，
直接或经过比较后推动开关元件，改变开关元件的通断状态，达到控制被测压力的目的。
