System generally comprises of one set of telescopic tubing of required height. The length of tubing generally depends on the
maximum convergence accepted in the cavity or a little more than the range of sensor. Both the tubing has anchoring flanges at one end for fixing it with roof and floor where as free end moves in each other in perfect alignment. The sensor is completely water proof and fixed outside on extended plate
assemblies for installation ease. Optional model with inbuilt sensor in the tubes is also available. Maximum convergence range up to 300 mm (500mm in case of resistance type sensor) is available in this model.
Top flange assembly is provided with height adjustment extension pipes to suit cavity height. Basic assembly height is 2 meters.
