Abstract
A force transducer comprises a housing having a front and rear portions joined together by a platform, which platform is thinner than the housing portions. The platform contains at least one sensor which is operative to provide an output according to the extent of compression or expansion of the platform when a force is applied to the transducer housing. A compliant tubular member is secured at one end to the front portion of the housing and at the other end to the rear portion of the housing. The compliant tubular member surrounds the sensor to protect the sensor from the surrounding environment. The tubular member expands and contracts compliantly with the applied force so that the sensor which is mounted on the platform is substantially unimpeded by the tubular member and provides an output directly proportional to the force applied to the housing.
