DWYER壓力開關 1910-20壓力表 DWYER pressure switch 1910-20 pressure gauge

1900系列 微差壓開關是最通用的系列產(chǎn)品，技術先進，結(jié)構精密，性價比高。它為空調(diào)系統(tǒng)而設計，也用于其它多種工業(yè)場合。 1900系列開關的設定點從0.07到20"英寸水柱(1.8到508毫米水柱)，用于空氣或兼容氣體。設定點很容易調(diào)節(jié)，調(diào)節(jié)螺絲被保護在外殼內(nèi)，以防止誤調(diào)。產(chǎn)品通過了UL，CE，CSA和FM認證。

警告：產(chǎn)品只能用于空氣及兼容氣體

DWYER pressure switch 1910-20

The 1900 series micro-differential pressure switch is the most common series of products with advanced technology, precise structure and high cost performance. It is designed for air conditioning system and also used in many other industrial occasions. The set point of the 1900 series switch ranges from 0.07 to 20 "inch water column (1.8 to 508 mm water column), which is used for air or compatible gas. The set point is easy to adjust, and the adjusting screw is protected in the housing to prevent misadjustment. The product has passed UL, CE, CSA and FM certification.

Warning: The product can only be used for air and compatible gases
