Product Description

Description

Omega Gaging Transducers are high precision measurement probes intended

for all Gaging applications demanding high accuracy and a high degree of

repeatability. The one piece parallel body houses a precision linear ball sleeve

bearing assembly, anti-rotation guide and the choice of either a half bridge or a

L.V.D.T. winding, a combination which adds up to an extremely versatile,

accurate and cost effective measurement solution.

Installation Recommendations

Location & Clamping

L.V.D.T. Gaging transducers generally are a reliable and proven technology that

is well established in all areas of manufacturing and quality control. The majority

of the associated problems experienced with their application and use are totally

avoidable, particularly if sufficient thought is given during the initial design stages

of equipment, to the position and clamping methods employed for these

measuring elements.

L.V.D.T.’s being of inductive nature are susceptible to some degree to the

influence of magnetic fields and therefore should be positioned well away from

electric motors, relays and permanent magnets, where this is not possible then

magnetic shielding should be considered as an alternative.

Clamping of the probe body should be carefully considered, ideally the body of

the transducer should be clamped in a pinch or yoke type clamp, if this is not

possible then the introduction of a load spreading bush between body and clamp

is a preferred alternative.

Irrespective of clamping method care must be taken not to overtighten retaining

screws as distortion of the body may prove damaging to the integrity of the

transducer and adversely effect the geometry of the installation.

Where single point screw clamping is adopted then the tightening torque

employed should be limited to that which will give a maximum of 50Kg point load.

The typical maximum torque for an M5x0.8mm or a 10-32UNF screw would be

approximately 0.27Nm.
