Stainless Steel Level Switch
A stainless steel level switch is a compact switch in which a reed contact inside a stainless body is operated by a magnetic stainless float sliding outside it. It offers higher temperature, pressure and mechanical strength than plastic types.
The store range includes stainless switches with ½” threaded connection, in socket and cable versions. Body and float are AISI 304 as standard; AISI 316 or PTFE-coated options are available for aggressive liquids.
Main Applications
- Hydraulic and lubricating oil tanks
- Fuel day tanks
- Hot water and condensate tanks
- Machine coolant reservoirs
- Food and beverage process tanks (316 option)
