ps压力开关原理PS压力开关原理一、引言PS压力开关是一种常用的电气元件，广泛应用于各种机械设备中，如空压机、水泵等。

它的作用是根据系统压力的变化来控制设备的启停，以保护设备的安全运行。

本文将围绕PS压力开关的原理展开详细介绍。

二、PS压力开关的基本结构PS压力开关主要由压力感应器、控制电路和输出装置组成。

其中，压力感应器用于感知系统的压力变化，并将其转化为电信号。

控制电路根据压力信号的大小，判断是否达到设定值，进而控制输出装置的状态。

三、PS压力开关的工作原理1. 压力感应器的工作原理压力感应器通常采用弹性元件（如弹簧）和敏感元件（如压力膜片）相结合的方式，通过受压后的形变来感知系统的压力变化。

当系统压力达到设定值时，弹性元件和敏感元件会产生相应的形变，从而改变电路中的参数（如电阻、电容等），进而产生电信号。

2. 控制电路的工作原理控制电路是PS压力开关的核心部分，它负责判断压力信号的大小，并根据设定值来控制输出装置的状态。

控制电路通常包括比较器、电阻网络和输出驱动电路等。

（1）比较器：比较器是控制电路的核心元件，它将压力信号转化为电压信号，并与设定值进行比较。

当压力信号大于设定值时，比较器输出高电平，反之输出低电平。

（2）电阻网络：电阻网络用于调节设定值，通常由可变电阻和固定电阻组成。

通过调节可变电阻的阻值，可以改变设定值，从而满足不同压力范围的需求。

（3）输出驱动电路：输出驱动电路根据比较器的输出信号，控制输出装置的状态。

当比较器输出高电平时，输出驱动电路闭合，使输出装置工作；反之，输出驱动电路断开，输出装置停止工作。

四、PS压力开关的应用场景PS压力开关广泛应用于各种机械设备中，主要用于以下几个方面：1. 空压机：PS压力开关用于感知空气压缩机的工作压力，当达到设定值时，控制空气压缩机的启停，以保护其正常运行。

2. 水泵：PS压力开关用于感知水泵系统的压力变化，当达到设定值时，控制水泵的启停，以保护水泵不因压力过高或过低而造成损坏。

There may be potential difficulties in ensuring electromagnetic compatibility in other environments due to conducted or radiated disturbances.• Refer to the operation manual or catalogue on the SMC website (URL: https:// ) for more safety instructions.2 Specifications2.1 General specifications2.2 PS1000 / PS1100 switch specification2.3 PS1200 switch specification3 Installation3.1 InstallationWarningDo not install the product unless the safety instructions have been read and understood.3.2 PipingCaution• Before connecting piping make sure to clean up chips, cutting oil, dust etc.3.3 EnvironmentWarning• Do not use in an environment where corrosive gases, chemicals, salt water or steam are present.• Do not use in an explosive atmosphere.• Do not expose to direct sunlight. Use a suitable protective cover.• Do not install in a location subject to vibration or impact. Check the product specifications.• Do not mount in a location exposed to radiant heat.3.4 LubricationCaution• SMC products have been lubricated for life at manufacture, and do not require lubrication in service.• If a lubricant is used in the system, use turbine oil Class 1 (no additive), ISO VG32. Once lubricant is used in the system, lubrication must be continued because the original lubricant applied during manufacturing will be washed away.4 Wiring4.1 Wiring• Connections should be made with the power supply turned OFF.• Use a separate route for the product wiring and any power or high voltage wiring. Otherwise, malfunction may result due to noise.• Incorrect wiring may cause damage to the pressure switch, breakdown and malfunction. Confirm the colour of the wires with the operation manual before wiring.• Wiring applying repeated bending and tensile stress to the lead wire can break the circuit.• The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the outside diameter of the insulation material, whichever is larger.• Avoid defective insulation (crossed lines with other circuit, ground fault, defective insulation between terminals, etc.) with the wiring.Excessive current can flow through the pressure switch, which may cause damage.• If the pressure switch is turned on with no load connected to the switch, over current will flow, causing the pressure switch to break instantly. • The pressure switch has no reverse connection protection for the brown (+) and blue (-) of the power supply line.• Do not exceed the maximum allowable load (24 VDC,40 mA) specified.4.2 Circuit Diagram4 Wiring (continued)4.3 Wiring diagramExample of connection to a PLC (sequence controller). (Source Input type)(Sink Input type)5 Setting• Adjust the calibration adjustment to set the ON pressure.• Rotate clockwise to increase the set pressure. For setting vacuum pressure rotate anticlockwise.• For setting, use a flat blade screwdriver suitable for a trimmer. Rotate lightly to adjust.• The rotation angle of the trimmer is 220°.There is a stop provided to prevent the trimmer from rotating beyond its limits. Rotation beyond the limits can damage the trimmer. Adjust the trimmer gently within the rotation angle.Caution• Do not use a large screwdriver as this may damage the trimmer groove. • Gently turn the trimmer and do not exceed the trimmer adjustment range.5.1 HysteresisHysteresis is the pressure difference between the ON and OFF pressure.
