Source holders offered by SENTINEL include a comprehensive choice of designs which match original equipment manufacturer specifications and are fully compatible with most current makes of gamma radiography projector.
The patent connector design is constructed from hardened steel and manufactured to critical dimensional tolerances. The force of the integral stainless steel sprung plunger is tensioned precisely to always provide a secure and positive connection to the control drive cable. The assembly, swaged to the teleflex cable, has an unmatched record of safety and wear resistance in the industrial radiographic industry.
The stop ball, made from stainless steel, is precision drilled, accurately positioned and secured in place with three point high pressure swaging. Precise positioning of the stop ball ensures that the source can be accurately and safely stored within the projector.
Sources capsules are constructed using either stainless steel or titanium alloy hermetically sealed by tungsten inert gas fusion welding and finished to exacting standards. Every capsule is subjected to a series of quality inspection tests to ensure weld integrity and uniform wall thickness.
The source capsule is securely attached to a distortion and fray resistant teleflex cable by swaging under high pressure. The resulting bond is tensile tested for optimum strength well beyond normal operational limits. The teleflex cabling, consisting of spiral wound flexible steel, has proven to be consistently durable and reliable over many years of use.
