The Shridhan Bilge Level Switch is designed for safety-critical liquid level detection where reliable indication of rising liquid, leakage or flooding is required.
The switch is constructed from corrosion-resistant 316 stainless steel and is fully submersible. A hermetically sealed SPDT reed switch is potted in epoxy, while an integrated manual lift test mechanism allows the switch operation to be checked.
Its compact construction, integral mounting bracket and stainless-steel slosh and debris protection shield make it suitable for installation in demanding environments.
The brochure specifies applications in ship bilges and tanks, industrial sumps and tanks where the switch is bolted at the required alarm level.
These features are stated in the manufacturer's Bilge Level Switch brochure. :contentReference[oaicite:1]{index=1}
The Bilge Level Switch is positioned at the required alarm level. As liquid rises around the switch, the float mechanism actuates the internal reed switching arrangement.
The switching element is a hermetically sealed SPDT reed switch housed within the stainless-steel construction and potted in epoxy.
The integrated manual lift test mechanism allows the installed switch to be manually actuated to check its operation.
