A device is described whereby the accurate machining of a metallic barrel/cylinder and it's ability to form an interference fit into an accurate hole can provide for an easily attached/installed instrument into a body who's parameters are to be measured. On a housing, physically part of the barrel, and in the barrel itself are bonded/attached sensing components, which can measure electronically, the parameters to be measured. These parameters are seen as being force/strain, temperature, vibration and acceleration. These components are strain gauges, temperature sensors and accelerometers as shown in the accompanying drawings. The sensor also has an inbuilt electronic amplifier and other electronics to digitise and data reduce the outputs of the sensors. There is also capacity to carry a dry cell voltage power source. The unit can also transmit digitised data via a telemetry system. An alternative mechanical system involving the barrel, a sleeve made of more resilient material than the barrel, and the body is also described. The intention is to provide a more consistent electrical output from installation to installation and provide good thermal conductivity from the body to the barrel/temperature sensor.
