LEVEL SWITCHES - TOP-MOUNTED LEVEL SWITCHES ARE DESIGNED TO PROVIDE RELIABLE OPERATION IN SEVERE INDUSTRIAL APPLICATIONS. THE UNITS CONSIST OF A VERTICAL GUIDED TUBE WITHIN WHICH ARE LOCATED SENSOR SWITCHES; MAGNETIC FLOATING SLIDING OVER THE STERM ACCORDING TO THE LEVEL IN THE TANK; AND SWICH HOUSING AND NECESSARY MOUNTING CONNECTION. USED ARE REED SWITCHES HERMETICALLY-SEALED AND ENCAPSULATED IN THE STEM. BECAUSE THE SWITCHES OPERATE ON THE PRINCIPLE OF MAGNETIC-FLUX COUPLING WITH TO MECHANICAL CONNECTION, FLUID CONTAMINATION OF SWITCH COMPONENTS CANNOT OCCUR. OTHER TYPES LIKE SIDE-MOUNTED, EXTERNAL CAGE LEVEL SWITCHES ARE ALSO OFFERED.

Side mounted level switch - Cristal Instruments manufactures side mounted level switch that can be used for initiating high/low level audio/visual signals and automatic level control of liquids in tanks. Switch actuation is by micro-switch that possesses SPDT contacts of current rating 5 A at 240 V AC and it operates normally at 12 mm liquid level differential. Float and all wetted parts are of SS -304/316, PVC or Teflon and the switch is designed for maximum pressure rating of 40 kg/cm2 and temperature of 300 degree Celsius. It is suitable for mounting directly on the side of the tank and the mounting flange is of SS square type having 83 mm PCD with four boltholes of 9 mm diameter as standard. The other sizes are available on request. SS switch housing that is weather-proof is given as standard feature, flame-proof material as per IS-2148-1981 standards for grade I, II A and II B gases is offered on request and the type of switch is suitable for liquids with specific gravity ranging from 0.7 to 1.2. Low-cost miniature type switches are also offered for atmospheric pressure and ambient temperature applications.
