- Free core LVDT used to measure displacement of thermostat valve
stem for diesel truck engine monitoring system.
- Free core LVDT used to measure the displacement of diaphragm in
automated whole blood processing equipment. (LVDT base pressure transducer)
- Free core LVDT provides Linear actuator feedback position used in
boiler systems.
- LVDT incorporated into proportional valve assembly providing position
feed back.
- Free core LVDT used for Blood-testing device measuring the displacement
of blood cells as they contract. Clinical usage, diagnosis of blood
disorders.
- Spring loaded LVDT used for brake pedal position for brake by wire
system.
- Spring loaded LVDT used in steer by wire system attached to rudder
assembly.
- Measuring with a free core LVDT for very small displacements for
high performance automotive drive and crankshaft shaft balancing machine.
- Special LVDT designed to measuring displacement of diamond tip to
determine material hardness.
- Use of special LVDT with SAE fitting welded to one end rated at
1500 PSI for measuring displacement of piston stoke in variable rate
pump assembly.
- Providing position feed back of seat movement for damping device
in agricultural equipment. (reducing operator fatigue)
- Position feed back in high speed injection molding machine (die
closure)
- Measurement of die wear, high speed injection molding equipment.
- Spring loaded LVDT used for position feed back for automated spot
welding control system.
- Special LVDT design used in linear actuator position feed back aircraft
ailerons.
