Endress + hauser [india] offers liquiphant t, a universally applicable limit switch, for level detection of liquids in storage tanks, process tanks and piping. This low cost, limit switch designed to survive difficult conditions can also be used in systems where other measuring principles cannot be applied, eg, for paste build-up, turbulent liquid flow, liquids with gas bubbles and rapid temperature variations when cleaning. The limit switch from endress + hauser enables maximum and minimum detection in tanks and vessels containing liquids with temperatures between 40c and 150c, viscosity of 10,000 cst and minimum density of 0.5 g/cm . The patented piezo-drive for vibrating forks is insensitive to outside vibrations [eg, pumps]. The rugged, corrosion-resistant synthetic housing of the limit switch features ip 66 protection and the optional halar covering a sensor length up to 6000 mm, which ensures application in corrosive liquids. The limit switch can be used to prevent the dry run of pumps. This limit switch is maintainenance-free and has no moving parts. Thus the limit switch provides a universal solution for all types of level control in liquid and viscous products.
