M-60X Series Ex-proof Fixed Set Point Flow Switches from Malema

M-60X Series Ex-proof Fixed Set Point Flow Switches from Malema
The M-60X Explosion Proof Series switches monitor increasing and decreasing flow. They utilize a single moving part which responds to fluid (liquid or gas) flowing within a system (universal mountable units are fitted with a reset spring). These switches are suitable for a wide range of applications in industrial, biomedical, and OEM products. The flow switch operates only when fluid is positively established.
