The Revolutionary Digital No-Flow Timer for Compressor Lube Syst
DNFT performs monitoring and shutdown functions like No-Flow, Low-Flow or Excessive-Flow for Divider-Block 
Lubrication 
Syst. The DNFT is a totally enclosed solid state electronic device for detecting Slow-Flow and No-Flow on in-line 
progressive 
lubrication syst. The Digital No-Flow Timer incorporates a crystal oscillator to accurately monitor the cycle time 
of the 
lubrication system enabling precision timed shutdown capability. An internal Lithium battery powers it, which is easily 
replaceable.
The Digital No-Flow Timer is an ISO 9001 certified product and the ISO certification can be viewed here. All Digital 
No-Flow 
Timers also come with a 3 year warranty.
The DNFTs come in three models to switch voltages up to 240 VDC:

DNFT无油开关

 注油器：整个润滑系统的较重要的部件，美国Premier公司是**较早生产盒式注油器的厂家之一，产品被**绝大多数**压缩机厂家采用。Premier的注油器自带减速机构，客户可以根据自己的需要选择驱动方式、减速比、油盒大小和单泵的数量。
·分配器：分配器由标有数值和字母的各个分配阀组成，较少需要三个分配块。其特点为各个出油口的润滑油排量按照标定数值比例分配到每个润滑点上，可以根据需要灵活组合阀块的数量，整个分配器上油路相同，有一个阀块不能工作的话其它所有的阀块都不能工作，便于集中控制。
·过滤器：通常有两次过滤，在润滑油进注油器前使用一个粗过滤器，和在进分配器前用一个高压过滤器。
·无油流开关：用来探知分配器的柱塞运动情况来探知系统的油流情况，通常的为无油流两分钟报警，也有58秒、3分钟的无油流报警。
·单向阀：常用的单向阀有单球和双球的单向阀。
·油位开关：用来检测油箱里油位的高低。
·驱动方式: 可以选择外用电机驱动或使用压缩机本身曲轴带动。
