The inductive displacement measurement principle has penetrated many sectors of industry and research because it is both robust and maintenance-free. We import and distribute the following displacement transducers:-

L VDT General Purpose DC L VDTs

Potentiometer

Rectilinear Displacement Transducer

• Range: 50-900mm


• Linearity: + 0.05%


• Infinite Resolution

Rectilinear Displacement Transducer with Ball Tip

• Range: 10", 50mm


• Linearity: + 0.1%


• Infinite Resolution

Digital Output

• An incremental encoder as the sensor, the series position transducer provides a two-channel square wave current sinking output signal in quardrature.

Alternative outputs in the electrical outputs table are available to facilitate interfacing to a variety of different types of equipment,

The actual resolution of a transducers from unit to unit because associated with the wire rope diameter and the capstan upon which the wire rope winds.

Linearity and repeatability remain independent of resolution.

Application

• The output count is interpreted, as a percentage of total travel resolution differences from unit to unit are not critical.


• The digital output is to be interfaced to a digital display to give an output in engineering units, the calibration constant supplied with the transducer may be used to calculate a suitable scale multiplier to produce the correct engineering units.
