Linear Variable Differential Transformers (LVDT)

Brain surgery is something nobody wants to go through, but is often necessary to treat symptoms of Parkinson’s and other neurological diseases. A medical products company has developed a sophisticated modular probe drive to support streamlined implantation of deep brain stimulating electrodes. This device addresses the clinician’s need for precise placement of electrodes for... Read more...

The Series 350 DC-DC Gaging Transducers offer a convenient solution to position sensing with all supporting electronics located internally and packaged together with a durable spring-loaded spindle. Complete electronics provide DC-in/DC-out operation while the spring actuation feature allows for minimal contact to the tip of the transducer. Similar to a customary LVDT with a free-floatin...

LVDT stands for Linear Variable Differential Transformer. An LVDT is also referred to as a linear displacement transducer, or linear position transducer. This sensor device measures linear displacement (or linear position) very accurately. The basic technology behind an LVDT is described below. Technology: the typical LVDT sensor consists of a primary coil and two secondary coils... Read more...

Model MVL7 AC-AC Long Stroke Displacement Transducer with free unguided armature, ranges from ± 0.5 to ± 8.0 in and an accuracy of ± 0.25% of full scale. Outputs ranging from 2.4 V RMS @ 3 V RMS to 9.5 V RMS @ 3 V RMS depending on the stroke length. Supply that can operate from either a 5 vdc calibrated power supply or a 1 V to 7 V RMS acceptable power supply. Unit c... Read more...

Measurement Specialties (MEAS), a worldwide leading manufacturer and pioneer in the development of sensors and sensor based systems, has just released an informative application note on how subminiature LVDTs provide accurate flight control feedback for Unmanned Autonomous Vehicles (UAVs). Read the application note here. The complex systems employed on UAVs use a myriad of e... Read more...

The Series 200 Short Stroke DC LVDTs are available in ranges to 0.2" total travel. The short body length makes these transducers suitable for use where space is at a premium. For convenience, Trans-Tek also offers Power Supplies and a Transducer Indicator for use with these units. Main Features: Measurement Ranges ±0.05 to ±... Read more...

Gaging (spring-loaded) LVDTs are used in a wide variety of applications. Several of the more common methods of use have been documented in detailed articles. These articles have been converted to PDF format and are listed below for your review. Keeping Mt. Rushmore Stable (26 kbytes) A modified version of a DC Gaging unit withstands harsh conditions while monitoring this ro... Read more...

Transducers embodied in valves used for controlling oil flow in undersea pipelines have been developed by RDP to operate with high accuracy and high reliability. RDP’s LVDTs are supplied to several valve manufacturers for use with valves controlling the flow of oil from pipe networks on the bottom of the sea, close to the well head. The transducers are u...
