High Pressure Switch with Piston&Diaphragm (YTK-18H)

YTK-18H High Pressure Switches

High working prssure up to 400bar.
Proof pressure can be 600bar.
Piston and diaphragm combination sensor, ideal for compact air, light fuel, lubric.


  
YTK-18H Dead Band Adjustable (Narrow Dead Band)

Example: choose order content No.0916700 product, a contact signal is required to be generated when pressure raises to 5Mpa( the Increasing Set Point). The steps listed as the following:

  1.1 Loosen the locknut, before setting, please screw the product into the threaded connection of test desk, simulate the real working condition to exert pressure on to the product 2 minutes. A spanner must be used to clamp the plane part of the sensor, in order to avoid the countermovement between the shell and the sensor.

  1.2 Open the cover, put the cable through the electrical connection into the terminal board, the other end to be linked with multimeter.

  1.3. Add pressure to 5Mpa, the value can be read from the standard menometer.

  1.4. Clockwise rotate the Set Point Adjusting Bolt, the Set Point value will become biger, until the contact points switches at 5Mpa.

  1.5. Tighten the locknut, and regulate the pressure of the testing desk to be arround at 5Mpa, to check if it switches at the 5Mpa when pressure rises. This is just the Increasing Set Point. The correspoding Decreasing Set Point should be 5Mpa minus the Dead Band 1.1Mpa(approximately), thus to be 3.9Mpa(approximately).
