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 DVRTs run harsh environments over millions of cycles without degradation in performance.

Friction-free LVDT sensors

LVDT sensors from LORD Sensing-Stellar are used for many different types of applications-- from precision dimensional gauging to monitoring of fault-line movement. All our LVDTs are fully welded and constructed of stainless steel, and utilize free unguided, captive guided or captive guided spring return armatures to meet the needs of the application. They are available in with stroke ranges from ±0.01” to ±18.5” with accuracies of 0.25 to 0.5 percent FS.

Performance, cost, and communication options

Each DVRT system consists of a sensor, cable, and signal conditioning module that are calibrated as one unit to ensure accuracy is maintained through the entire sensing solution. They are calibrated using a linear fit, multi-segment fit, and a polynomial fit, so interpretation of the measurements can be scaled to best suit the application requirements. Choose from the analog or wireless series of signal conditioners. Analog signal conditioners are available in high and standard-performance models. Wireless signal conditioners have standard performance, and are available with USB, RS232, Ethernet, and analog data outputs.
