DNFT performs monitoring and shutdown functions like No-Flow, Low-Flow or Excessive-Flow for Divider-Block Lubrication Systems. The DNFT is a totally enclosed solid state electronic device for detecting Slow-Flow and No-Flow on in-line progressive lubrication systems. 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.

DESCRIPTION

The DNFT-LED-PS is a totally enclosed electronic device, combining the latest technology in microprocessor and transistor components for detecting Slow-Flow and No-Flow of divider block lubrication systems. The DNFT incorporates an oscillating crystal to accurately monitor the cycle time of the lubrication system to enable precision timed shutdown capability. The magnet assembly and control housing mount directly to the divider valve to become an integral part of the lubrication system. The DNFT operates on a field replaceable lithium battery. If battery voltage drops below normal operating levels the DNFT goes into alarm mode and the unit cannot be restarted. LED models utilize an LED to indicate each cycle of the divider valve. This enables the operator to easily set and monitor lubrication rates.

  • Monitors movement of divider block piston for dependable “timed” shutdown protection
  • Closed loop or open loop operation
  • Installs directly to divider valve
  • Not affected by temperature or oil viscosity
  • Requires no external power
  • Led indicator - cycle indication
  • Dedicated switch closure to monitor each divider valve cycle (ps option)
