Side and Top Mount level switch
√ Corrosion-resistant plastic body; pivot pin in 316 stainless steel, HASTELLOY® C, titanium or PTFE (Teflon®).
√ 10 times less affected by deposits and build-up than sliding float switches.
√ Made-to-order 1¼″ × ¼″ × ½″ reducer bushing available for through-wall mounting.
√ Cable: 22-gauge twisted pair or two-core heavy-wall PVC instrument cable.
√ Standard SPST reed switch, 120/240 VAC, 50 W. Optional SPNC or SPDT, 3 W, 100 VAC/VDC.
√ Connects directly to controllers, or drives a small relay (coil 8 VA or less).
√ Switches at a level change of about 10 mm (3/8″).

Which version for which liquid
NORYL®: chlorinated, fresh, distilled and salt water; hydrochloric acid 20–37%; nitric acid 10–50%; phosphoric acid 40–100%; sulfuric acid 10%; sodium hydroxide (caustic soda) 20%; acetic acid; plating fluids and baths.
FORTRON®: fresh, distilled and salt water; phosphoric acid 40–100%; sulfuric acid 10%; sodium hydroxide (caustic soda) 20%; acetic acid; glycols; diesel, oils and lubricants; solvents such as benzene and xylene.
Please note: the switch works by a magnet. Iron or steel particles in the liquid can build up around it and affect how it works, so check the liquid for magnetic particles before installing.
