Stainless steel resistance level gauge

Resistance level gauge, Resistance level gauge, Resistance pendulum level gauge, Mechanical level gauge, Rotary pendulum level gauge

The UL series resistive level gauge is suitable for detecting the level of material in silos and containers during industrial production processes. When the level reaches the high and low limits, the level gauge outputs a relay contact signal for level alarm and control.
Working principle
The instrument adopts a mechanical swing transmission system. When the material blocks the detection board, the instrument relay status flips and outputs an alarm signal; When the material leaves the detection board, the instrument returns to the detection state.
