发明名称 Centralizer apparatus
摘要 A centralizer for an instrument such as an in-place inclinometer is described. The centralizer has a clamp with an inner receptacle configured for coupling to the instrument housing, and a plurality of elongate fingers extending from the clamp that center the instrument in the casing. The fingers carry rollers that fit into grooves in the instrument casing. The fingers are arcuate and provide a spring-like contact force that causes the rollers to abut the instrument casing and stabilize the instrument.
