ABSTRACT:
Method for monitoring the electrical integrity of a heater and a novel heater for use in such a method. The heater includes an elongate heating member; an insulating jacket which encloses the heating member; a first electrically conductive member which surrounds the insulating jacket; a separating and insulating member which surrounds the first conductive member; and a second electrically conductive member which surrounds the first conductive member and is separated and insulated therefrom by the separating member. The method includes the step of testing the electrical relationship between the first and second electrically conductive members.
