String Potentiometers
(40 companies)
String Potentiometers are used to measure the movement and displacement of objects. A cable or wire is attached to an object, and as the object moves, the transducer produces an electrical signal proportional to the wire's linear extension.
Magnetostrictive Position Sensors
(32 companies)
Magnetostrictive position sensors are non-contact linear position sensors that use the momentary interaction of two magnetic fields to produce a strain pulse that moves along a waveguide. One field is from a magnet that moves along the outside of the waveguide. The other field is from the waveguide itself.

...or digital (serial, parallel, or other). Packaging can be a raw sensor element or a housed transducer. Self-contained instruments or meters display output at or near the device. Gauges/indicators have an analog display and no electronic output...
Impact Hammers
(57 companies)
Impact hammers are used in structural and modal analysis to determine component or system response to impacts of varying amplitude and duration. A hammer with a force transducer in its head is paired with an accelerometer on the component being tested to compare impact and response.
Linear Variable Differential Transformers (LVDT)
(99 companies)
Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core. These devices produce an electrical output proportional to the position of the core

Loop Powered Devices
(17 companies)
Loop powered devices are electronic devices that can be connected in a transmitter loop, normally a current loop, without the need to have a separate or independent power source. Typical loop powered devices include sensors, transducers, transmitters, isolators, monitors, PLCs, and many field instruments.
Vibration Measurement Instruments and Vibration Analyzers
(356 companies)
Vibration measurement instruments and vibration analyzers are used for measuring, displaying and analyzing vibration. Typically these instruments comprise a transducer, data acquisition and either a local display or some sort of output to a computer or another instrument.
