The gauge features: resistance to environmental vibrations and withstanding pulsation of
medium and load's striking. It adopts contact-less induction switch. Its electric signal convertible
equipment, sensibility high, control precision high and respondence quickly. It has no laggardly leap
phenomena. Switch features are good. It is formed a complete set of YXG-K.

Model	Schematic diagram	Type of contact	Location of control strip varies with motron of indicating needle	Equivalent touch type contact
YXG-150-Z21		Upper limit, lower limit	1.Both control strips are located inside the induction switch 2. When indicating needle moves upstream (or downstream), control strip of upper limit contact (or lower limit contact) withdraws from the induction switch.	1.Both contacts are open, output high impedance. 2.Upper limit contact (lower limit contact) closes, output low impedance.
YXG-150-Z11		Double upper limit	1.Both control strips are located inside the induction switch. 2.When indicating needle moves upstream, control strip of contact land 2 successively withdraws (leaves) from the induction switch.	1.Both contacts are open, output high impedance. 2.Contact 2 and 1 successively closes, output low impedance.
YXG-150-Z22		Double lower limit	1.Both control strips are located inside the induction switch. 2.When indicating needle moves downstream, control strip of contact 2 and 1 successively withdraws (leaves) from the induction switch.	1.Both contacts are open, output high impedance. 2.Contact 2 and 1 successively closes, output low impedance.
YXG-150-Z1		Single upper limit	1.Control strip is located inside the induction switch. 2. When indicating needle moves upstream, control strip of contact withdraws (leaves) from the induction switch.	1.Contact is open, output high impedance. 2.Contact is closed, output low impedance.
YXG-150-Z2		Single lower limit	1.Control strip is located inside the induction switch. 2. When indicating needle moves downstream, control strip of contact withdraws (leaves) from the induction switch.	1.Contact is open, output high impedance. 2.Contact is closed, output low impedance.
Note： in the schematic diagram:            Control strip is inside the induction switch, it indicates that the contact is under open state.            Control strip is outside the induction switch, it indicates that the contact is under closed state.
