Madison Liquid Level Switch 1/4 NPT Selectable 316 SS

Liquid Level Switch 1/4 NPT Selectable 316 SS

The Madison liquid level switch provides selectable switch function for open tank mounting with a 1/4 inch NPT connection. Constructed from 316 stainless steel, it withstands pressures up to 200 psi and operating temperatures reaching 482 degrees Fahrenheit. The SPST contact form handles a maximum of 0.5 amps at 240 volts with a 60 VA rating.

Suited for industrial tank monitoring requiring

This unit fits vertical installations where a compact 3.52 inch overall length and 2.08 inch float length meet space constraints. Buyers needing horizontal mounting, larger conduit sizes, or different contact forms such as SPDT should consider alternative switch designs. The fixed 1/4 inch NPT tank connection limits direct compatibility with other thread standards.

Installs vertically through a 1/4 inch NPT tank

The 316 stainless steel stem and float resist chemical attack, reducing seizure risk during long service. Misalignment during fitting can restrict float travel, so verify the 2.13 inch float diameter clears internal tank structures. Over-tightening the conduit connection may damage threads, and exceeding the 0.5 amp current rating will shorten contact life.
