LORD MicroStrain® World’s smallest displacement sensors

Ideal for precise micro-position measurements, our Displacement Variable Reluctance Transducers (DVRTs) provide accurate, repeatable measurement. Inductive contact, non-contact, slide, and spring-actuated sensors are available in various stroke lengths– ideal in spaces where traditional LVDTs are too large. Our sensors operate in harsh environments over millions of cycles without degradation in performanceLORD MicroStrain® wireless sensor nodes offer low-power, embedded monitoring without the need to install or maintain wires.
