Automatic Reset Pressure Switch
用途:
主要用于家用、商用、汽车制冷系统的高、低压力保护控制，也可适用于各种设备工具的高、低压力保护控制。
Usage
These switches are mainly used in high/low pressure protection control for the refrigerating system of household,commercial and automobile as well as for various kinds of equuipments and tools.
特点：
采用英制管螺纹快速接头或铜管焊接式安装结构，安装灵活，使用方便，无需特殊的安装固定。
插片式导线式连接方可供用户任意选定。
单极单置或单极双置，常开式或常闭式开关接点结构可供任意选择。
密封式不锈钢感应器安全可靠。
在3～650PSI（0.02～4.5Mpa）压力范围内可根据用户任意选定的压力值进行制造。
Characteristics:
Adopting BSP screw quick connector of brass pipe-welded structure,they are flexible to be mounted and easy to be used without special installation and fixation.
The insert-style and wire-connected styles are avaailable for choice.
Single-pole-single-throw or single-pole-double-throw,normal-open or normal-close contacts of switch are available for choice.
Airtight stainless steel sensor is safe and reliable.
Any pressure within the range of 3-650PSI(0.02-4.5Mpa)can be selected to customize according to customer’s choice.
工作原理：
当系统内压力高于或低于额定的安全压力时，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。
Working Principle:
When the pressure inside the system is over or below the related safe pressure the disc in the sensor will start to move ionstantly,and this works together wit the connecting rod and pustes the switch connector to open or close.When pressure reduces or rises to the rated point,the disc will be reset and the switch will be reset automatically. |
