Besides, it provides high repeatability and effect of shocks/vibrations is minimal. Construction & OperationSimple and sturdy construction, consisting of a float and guide tube, made of nonmagnetic material to achieve an undisturbed magnetic flux. The float has a magnetic system within it and moves freely along the guide tube, which contains glass encapsulated hermetically sealed switches, located at preset positions. Reliability of float movement is achieved through suitable clearance between it and the tube. Float follows the liquid level and magnetically actuates the contacts to give an electrical signal, which in turn can operate remote alarm or a relay to control auxiliary devices like solenoid/motorized valve or pump motor starters. Single/multiple switching is possible through a single float, however to suit specific applications, multiple floats can be employed. The Tube Type Liquid Level Controller is available in various materials and construction styles to suit wide variety of medias/applications. InstallationsMounted internally or externally through a chamber. External mounting adopted to overcome limited space within the tank or where mechanical devices like stirrers operate or where isolation tank is required for regular servicing. It can be installed vertically from top to bottom. Side installation is also possible with slight modification. Control UnitContains electronics and comes separate as an accessory to the sensor. To allow low power switches to control high amperage or voltage devices. Or To convert non-latching switch outputs into latching alarm outputs. The relay provided in the Controller is of 5 Amp. Capacity. On no account must a switch be used for the direct starting of burners, heaters, motor pumps, alarm, it is essential that the contacts are wired in series with the relay coil (N/V coil) in a contactor starter.
