Korea’s top class Flow and Level Instruments manufacturer with 45 years of history
Overview
HR-30 Series is a Float Type Level Switch which is basically operated with the usage of reed switch and magnet. It can be applied to various storage tanks as well as highly corrosive liquids, and can be widely used in general industries with high reliability and long life cycle.
Characteristics
- Widely used to measure various liquid
- Applicable to corrosive and acidic liquids with anti-corrosive material for the sensor (PVC and Teflon)
- Applicable to explosion area (Ex-Proof version)
- Strong structure and high reliability
- Long life cycle
Operation Principle
As liquid level is changed in the tank, the float which is manufactured in accordance with the specific gravity of liquid moves upward or downward along the guide pipe with the same liquid level by buoyancy. The built-in magnet in the float activates reed switch which is located in the guide pipe and contact signal is out. Each alarm or H/L control with multiple setting points is available.
