SL20 Float Level Gauge

SL20 float level gauge (switch output), also known as float level switch, is a kind of level control switch. It can bear the pressure of 2.5MPa at most, which is especially suitable for liquid level control or alarm in inflammable, explosive and closed high pressure occasions.

√ Safe and reliable operation with high stability

√ Easy installation, maintenance-free

√ A group of normally open and normally closed passive

√ Contacts are used for liquid level alarm or control
