Dual Float Switch for tank level control.
Crydom Magnetics has extended its range of
vertical mount liquid level sensors, solving the
problem of controlling the filling and emptying
of tanks where no microprocessor is available.
The new RSF66 addition features two independent switches and
floats combined into one vertical stem, which can be easily wired
to control pump circuits via simple electromechanical relays.
Each float switch is rated at 25VA with maximum switching voltage
Versions are offered as standard with 50mm or 100mm separations
between floats, with either 2 make on rise or 2 break on rise contacts.
Custom variants to suit particular applications and tank sizes can
also be offered from this low-cost and flexible design.
Made from a tough blend of glass re-enforced polyphenylene
sulphide (PPS), the RSF66 range can withstand working
temperatures up to 120oC and offers excellent resistance to
many aggressive chemicals and moisture ingress. These devices
carry WRAS and UL approvals.
