Abstract
A transducer for diesel fuel injection for monitoring which has a strain detector mounted on the circumference of the fuel line tube such that expansion and contraction of the tube cause variations of the output of the detector, a plastic sleeve covering the resistance element at least in some part, a torpedo-shaped housing made of strong metal encompassing the tube and the resistance element mounted thereon and rigidly attached to the tube circumferentially at outer positions away from the resistance element, the housing defining an annular space between the housing and the tube and containing the resistance element and the sleeve, a strong adhesive material filling the said space, and electrical leads from the resistance element passing to the exterior through openings in the housing.
