  • Sensing devices for mounting in chamber walls and a method of manufacture
    Patent number: 4548780
    Abstract: A sensing device incorporating a sensing element and terminals for making electrical connection to the device is manufactured by placing the sensing element and the terminals in a mould and injection moulding a plastics body around them. The integral plastics body firmly bonds the parts of the device together and is shaped outwardly with a screw thread and a hexagonal nut portion--for example--so that the device can be screwed into a threaded aperture in a chamber wall. One application is a temperature indicator screwed into an automobile engine block.
