SKF压力开关DSA系列介绍
DSA 压力开关监控润滑系统的压力并帮助评估其功能是否正常。它们监测压力升高、压头和压力降低等参数，例如在带有单线油量计量装置的间歇运行润滑系统中。开关压力出厂设置为即插即用操作。包含隔膜的压力单元和压力柱塞与微型开关组装在紧凑的塑料外壳中。外壳由玻璃纤维增强聚酰胺制成，并包含安装支脚，可快速轻松地安装。
特点和优势
易于接线和安装
简单高效的设计
具有成本效益的市场验证解决方案
开关功能可靠的微动开关
转换开关，适用于常闭触点（NC）和常开触点（NO）
开关压力出厂设置为即插即用操作
可用于 1 至 30 bar（14.5 至 435 psi）的上升和下降压力
DSA pressure switches monitor the pressure of a lubrication system and help assess it’s proper function. They monitor parameters as pressure buildup, pressure head and pressure reduction e.g. in intermittently operated lubrication systems with single-line oil metering devices. Switching pressures are factory set for plug&play operation. The pressure cell containing the membrane and the pressure plunger are assembled with the microswitch in compact plastic housings. The housings are made of glass fiber-reinforced polyamide and contain mounting feets for quick and easy mounting.
Features and benefits
Easy to wire and install
Simple and efficient design
Cost-efficient market proven solution
Micro switch for reliable switching function
Change-over switch, suitable for both normally closed contact (NC) and normally open contact (NO)
Switching pressure factory set for plug&play operation
Available for rising and falling pressures from 1 to 30 bar (14.5 to 435 psi)
