The SHI 'Short Heavy Industrial' LVDT displacement transducer consists of a standard linear variable differential transformer housed within a robust stainless steel body. The concentric tubes of the telescopic assembly are guided by means of a linear bearing and are retained by rigid end stops within the body. The fixed and moving ends of the transducer are fitted with rod end bearings for mounting purposes.
The version was introduced to provide long working strokes within minimum length bodies. The rugged and reliable construction of the series makes it particularly suited to Heavy Industrial applications and 'uncomfortable' environments. Of conventional LVDT principle these transducers are designed for use on low voltage AC supplies at frequencies between 50Hz and 5KHz.
The rod end bearings are screwed into the two body end sections and are fitted with lock nuts. The length of thread on one end bearing permits an adjustment of ± 6mm (± 0.25 inches) to provide a fine control of mechanical zero position.
