Yamashina Seiki Grease Flow Sensor

Product Made In Japan
Manufacture: Yamashina Seiki

This sensor connects to the piping line and checks whether grease is being sent from the grease pump to the lubrication point on a regular basis.

Preventive maintenance/improving operating rates

Early detection of poor lubrication in production equipment is possible.

remote monitoring

You can check the lubrication of dangerous areas that people cannot access on a daily basis.

Centralized management/automation/labor saving (cost reduction)

Grease discharge confirmation in daily operations can be changed from visual confirmation to automation.

Hazard prevention

Greasing can be checked from the outside even while the machine is in operation.

6 Features

  1. High-pressure compatible
    Can be used with pipe pressure up to 20.5MPa

  2. Can be used even in harsh environments due to the protection structure protection class IP65
  3. Safety design
    Structure that prevents contact corrosion because the electrical contacts do not come into contact with fluid.

  4. Stable detection Since two coils are compared for stable detection , the reference point does not shift due to temperature changes.
  5. The high temperature
    sensor does not use IC parts, so it can be used even at an environmental temperature of 120°C.
  6. Compact design
    allows you to connect 4 sensors with one amplifier
