TD-2 series absolute expansion sensor for measurement of steam turbine

TD-2 Series absolute expansion sensor for measurement of steam turbine steam turbine industry absolute expansion displacement sensor is designed, it is local and remote two instructions.Local indication of large visual field, which adopts intermediate frequency displacement sensor as the sensing element; remote  indication of good linearity, strong interference resistance, simple structure, uneasy damage, good reliability, can be a long-term continuous use, for constant current output.Is the domestic large and medium-sized steam turbine manufacturing plant selection, other precision measuring range displacement situation can also be used .
