Unguided version.
On our ACT unguided LVDTs the armature assembly is a separate component, to make a measurement the user must guide the armature inside the body without touching the sides. Our ACT unguided position measurement transducers are appropriate where external guidance is available and give truly non-contact operation
Captive guided version.
Our ACT captive guided displacement transducer has bearings to guide the armature inside the measurement sensor. Our ACT captive LVDTs are for position measurement applications where guidance may be poor and end bearings may be required.
Spring return version.
Our ACT spring displacement transducer has bearings to guide the armature inside the measurement sensor and a spring which pushes the armature to the fully out position. Our ACT spring return LVDTs are appropriate where it is not possible to connect the transducer armature to the moving component being measured.
