| The SR-W and DRW series waterproof linear variable differential transformers are designed for applications requiring total submersion or for use in situations where high humidity or condensation may be expected. These waterproof LVDTs are available in two series, the SR-W (AC input — AC output) or DR-W (DC input - DC output). The units have a fully sealed body with the connecting cable brought out through a V* BSP compression fitting suitable for use with copper or plastic pipe. For submersion in liquids up to approximately 20m depth (or equivalent pressure of 30 PSI or 2 atmospheres), a suitable sealing compound should be used within the compression fitting. For higher pressures (or greater depths) the use of Araldite AY18 and Hz 18 hardener is recommended and the manufacturer's instructions on cleaning surfaces and mixing should be followed. These spring loaded and guided-core displacement transducers consist of a magnetically shielded linear variable differential transformer contained within an outer stainless steel body which is threaded at the probe end for mounting purposes. Within this threaded end is a bush bearing to support and guide the stainless steel probe shaft. |
