External Cage Level Switch : CLS8
Cirrus Engineering manufactures External cage switch model CLS8 which are designed for mounting externally at the side of tanks. The external cage is made in CS or SS construction with flange or socket weld connections & with different liquid inlet orientations.
The external cage encloses a top mounted Level switch (cirrus CLS7). Due to rise of liquid Level inside cage the float along with stroke rod of switch moves in upward direction, hence raising the attractor. Attractor thus on lifting operates a magnetic lever mounted inside the switch enclosure, resulting magnetic lever to come in contact with the attractor. Due to this movement of lever, a microswitch is actuated giving potential free contact output. On reverse, when liquid Level falls inside tank & cage, the stroke rod & attractor moves down thus breaking the magnetic field & releasing of the lever & deactuation of microswich. The switches are available in single & double acting mechanism. Cages are also available in IBR versions for Boilers
Application: High pressure/temperature liquids, oil, pressure vessels, HP / LP heaters, condensate tanks, oil tanks, boilers, chemicals etc.
