Abstract:
An environmentally sealed instrument circuit adapter, comprising:contact sockets configured to mate with contact pins inside a connector header on a process transmitter, the connector header having a sealing surface, and also configured to connect with conductors of an instrument circuit; a rigid insulating support that supports the contact sockets; a sleeve with threads configured to screw onto the connector header, the sleeve having a lip; an environmentally sealing elastomeric boot configured to seal the circuit conductors of the instrument circuit and having a elastomeric rim between the lip and the sealing surface; and at least one washer located between the lip and the elastomeric rim, the washer having a washer surface that slides relative to the lip as the sleeve is screwed on so that twisting of the elastomeric rim is limited as the sleeve is tightened on the connector header to form a liquid-proof seal between the elastomeric rim and the sealing surface.
