 HTD Series Oil motive sensors 

 HTD series oil sensor is designed for measuring motivation for steam turbine valve opening stroke group designed, and HXW-Y-type oil-match motivation Monitor 

 Together with a remote valve position indication travel, alarm, constant current output function. 



 Medium frequency differential transformer displacement sensor as a sensing element, is a high reliability LVDT displacement sensors, anti-jamming 

 Ability, linear, simple structure, easy to damage, long-term continuous use. 

 Measuring principle: As shown, when the intermediate frequency signal in the spiral core moves within the coil, A and B and B and the impedance between 

 C produces changes in the impedance between, due to changes in impedance and core movement is proportional to the voltage change is linear with core displacement 

 Relationship, so remove the VAB, VBC can measure the voltage difference between the core displacement.
