LVDT vs SMAC LCA6 Actuator




Output Force LVDTs require a spring or air. If a spring, it is a set force determined by the spring rate. If air pressure, the LVDT requires additional pneumatic components and manual adjustment of air pressure to change force. Force is programmable.
Extension to Part The LVDT or the part must be moved to each other. Contains motor - can program position and velocity.
Cost LVDT alone is under $1000 but other required components and amplifiers drive costs must higher. LCA6 is priced comparable to an LVDT alone.
Accuracy Accuracy can improve as window of distance decreases. For SMAC high resolution is constant through the entire stroke.
Direct Drive Touch on Surface Being Measured LVDTs require mechanical assembly, no direct drive touch. No need for mechanical assembly; uses direct drive touch on surface being measured, making the job 100% accurate.
Compressed Air LVDT pneumatic systems make linear movement possible only through mecahnical assembly. SMAC actuators are electric 24 and 48 VDC and do not require compressed air.
Mechanical Adjustments LVDTs mechanical assemblies require constant re-adjustment. No need for mechanical adjustments on assembly.
Recalibration LVDTs construction requires constant recalibration. No need for actuator recalibration.
Pneumatic Drop Installations LVDTs require mechanical and pneumatic assembly. No need for pneumatic drops from building.
Periodic Maintenance LVDTs need periodic maintenance, including lubrication. No need for periodic maintenance.
