Height sensor

Former Member

Hi

actually i want to sense the height of suspension car model after i pull it up and down continuously using cylinder and air pressure...which type of height sensor(position sensor) is recommended for such operation ....?

  • There are lots of great linear position sensing technologies for harsh environments such the LVDT mentioned above. Others include Positek inductive position, Honeywell Smart magnetoresistive, Micro-epsilon magneto-inductive, Penny&Giles contactless linear, SenseAble magnetostrictive, etc. However these are all pretty expensive. There are many others thjat are lower cost, but require some mechanism to adapt to this application such as Hall effect, optical encoders, ultrasonics. etc. One low cost sensor you might be able to use is an optical proximity sensor such as a Sharp GP2Y0A02YK0F.
