The device emits X-rays towards the metal strip, and detection unit (21) on the other side of the strip detects the out-going X-rays, which are treated (22) to measure strip thickness and the resultant reading transmitted to the operator. The detector and treater are mounted on a support plate (18), with a closure plate (19) at one end, carrying electrical (27) and fluid (25,26) connections. The support plate is inserted in an enclosure, with a flange fixing for the closure plate, with a seal between the joint. The enclosure has an X-ray permeable window adjacent to the detector unit, towards the product and a protective screen, absorbing X-rays, covering any susceptible circuit components. The closure plate fluid connections provide liquid coolant. |
