Ashcroft雅斯科B420B系列壓力開關(guān)主要類別包括常開式和常閉式。

Ashcroft雅斯科壓力開關(guān)是與電器開關(guān)相結(jié)合的裝置，當(dāng)?shù)竭_(dá)預(yù)先設(shè)定的流體壓力時，開關(guān)接點動作。主要應(yīng)用于電廠、石化、冶金行業(yè)等工業(yè)設(shè)備上輸出報警或控制信號，在工業(yè)領(lǐng)域中有著重要的用途，能預(yù)防生產(chǎn)工程中重要裝置的損壞，避免了重大生產(chǎn)事故地發(fā)生。 

主要特點是：

1、采用英制管螺紋快速接頭或銅管焊接式安裝結(jié)構(gòu)，安裝靈活，使用方便，無需特殊的安裝固定。

2、插片式導(dǎo)線式連接方可供用戶任意選定。

3、密封式不銹鋼感應(yīng)器安全可靠。

4、壓力范圍內(nèi)可根據(jù)用戶任意選定的壓力值進(jìn)行制造。

include normally open and normally closed. The main categories of

Ashcroft B420B series pressure switches include normally open and

normally closed.

The Ashcroft pressure switch is a device that is combined with an

electrical switch. When the pre set fluid pressure is reached, the

switch contact acts. Mainly used for outputting alarm or control

signals on industrial equipment such as power plants,

petrochemical, and metallurgical industries, it has important

applications in the industrial field and can prevent damage to

important devices in production engineering, avoiding the

occurrence of major production accidents.
