The SB series LVDT displacement transducer features a large displacement range in a comparatively short and rugged stainless steel body. The robust construction makes the SB series ideal for applications where a short bodied, accurate, durable position feedback transducer is required. Electrical connections are made via a 2m length of integral cable or 4 pin connector. The rugged stainless steel body consists of a magnetically shielded linear variable differential transformer. These are designed for operation from low voltage AC supplies at frequencies between 50Hz and 5KHz. The transducer housing consists of a non-magnetic stainless steel body of 31.75mm diameter and in lengths according to the stroke length. An inner housing of magnetically permeable material shields the transformer from the effects of external fields. The 6.35mm diameter core extension shaft is guided by means of a PTFE bearing bush. On spring loaded versions the force required for full compression of the extension shaft varies from approximately 280 grms for the 25mm range to approximately 790 grms for the 150mm range. Various configurations are available to accommodate most industrial applications. The SB series can be supplied with a spring loaded core or captive core with rod end bearings. |
