美国Digital No-Flow Timer DNFT premier无油开关

Digital No-Flow Timer (DNFT) premier 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 LED model DNFT LCC model DNFT PRG model Slow Internet Connections DNFT LED 2 mins DNFT LED 2 mins DNFT LED 2 mins DNFT LED 2 mins DNFT LED 2 mins DNFT LED-PS 3 mins DNFT LED-PS 3 mins DNFT LED-PS 3 mins DNFT LED-PS 3 mins DNFT LED-PS 3 mins DNFT LCC 45 secs DNFT LCC 45 secs DNFT LCC 45 secs DNFT LCC 45 secs DNFT LCC 45 secs DNFT LCC 2 mins DNFT LCC 2 mins DNFT LCC 2 mins DNFT LCC 2 mins DNFT LCC 2 mins DNFT LCC 3 mins DNFT LCC 3 mins DNFT LCC 3 mins DNFT LCC 3 mins DNFT LCC 3 mins DNFT LCC 255 secs DNFT LCC 255 secs DNFT LCC 255 secs DNFT LCC 255 secs DNFT LCC 255 secs DNFT PRG 20 to 255 secs DNFT PRG 20 to 255 secs DNFT PRG 20 to 255 secs DNFT PRG 20 to 255 secs DNFT PRG 20 to 255 secs DNFT PRG 20 to 255 secs DNFT PRG-PS 20 to 255 secs DNFT PRG-PS 20 to 255 secs DNFT PRG-PS 20 to 255 secs DNFT PRG-PS 20 to 255 secs DNFT PRG-PS 20 to 255 secs DNFT PRG-PS 20 to 255 secs DIGITAL NO－FLOW TIMER， MODEL：DNFT－PRG， DNFT无油开关 注油器：整个润滑系统的较重要的部件，美国Premier公司是全球较早生产盒式注油器的厂家之一，产品被全球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。 DL -900 Monitor DL-920 Monitor DLM-820 Monitor DLM-821 Monitor DLM-830 Monitor DLM-831 Monitor 无油流开关DNFT-LED 无油流开关DNFT-LED-PS 无油流开关DNFT-PRG (Programmable) 无油流开关DNFT-PRG-PS (Programmable) 无油流开关DNFT-LED 无油流开关DNFT-LED-PS 无油流开关DNFT-PRG (Programmable) 无油流开关DNFT-PRG-PS (Programmable) PLS-018 Heater/Thermostat Assemblies PLS- Oil Level Controller/ Low Level Switch PLS-020 Premier Lube Guard Assembly PLS-021 P-498 Oil Level Controller
