Korea’s top class Flow and Level Instruments manufacturer with 45 years of history
Overview
HM-95 Series is a Float Type Level Switch which detects liquid level by using of float and is mainly applied for high temperature and pressure vessel such as Boiler drum, Petrochemical Industry and Power plant, etc. It is used for the process performing alarm function when filling and discharging of the tank. Weather Proof and Ex-Proof version are available in accordance with requirement of site.
Characteristics
- Widely used to detect various liquid levels
- Strong structure and long life cycle
- Applicable to high temperature and pressure
- Easy installation
- Applicable to explosion area (Ex-Proof version)
Operation Principle
When liquid level rises, the core connected to the float is also rising. The movement of core produces the contact output signal (SPDT or DPDT) by switching mechanism.
