LVDT sensor VMI
Heavy-duty inductive displacement transducer with measuring ranges from 20mm to 100mm for use in power plants for measuring the housing expansion of turbines. The robust meetaster in aluminium housing with internal spring and optical scale has a coil unit with fully symmetrical coil construction. The precision bearing of the probe rod allows high load cycles even in harsh environments. Variants with different connection versions of plugs and cables as well as for operation of elevated temperature are available. The integrated electronics can be designed in 2-, 3- and 4-wire technology with different Supply voltages and Output signals.
